1) A new TF300 digitizer is just under $100.00 right now.. It is ONLY a slate of glass with a thin ribbon cable hanging from it.. It is just the Touchsensor.. No display at all.. If you have damaged your LCD - this is separate..

2) The digitizer is doublesided sticky taped to the bezel using a 1/2" or so wide tape (really thin) with real aggressive adhesive - highly recommend using heat gun or hair dryer to remove digitizer from bezel. Be careful not to get the plastic bezel too hot.. The digitizer is ALSO doublesided sticky taped to the LCD using 2mm or so wide foam tape. How to reassemble? Haven't got there successfully yet.

3) Backlight panel? I think you are referring to the LCD display itself.. Please refer to the original post.. Other than sticky tapes - the ONLY thing holding these assemblies in is their wiring.. eg: if you free the digitizer from the tape holding it to the bezel and the tape holding it to the LCD - remaining is only the ribbon cable.. Referring to the original post, note that the ribbon cable is the gold ribbon on the lower right next to the wiring with the masking tape on it.. There is a black foam sticky pad over the two connectors that have hinged latches holding the connections in.. No screws are ever necessary in any part of this process. The gold ribbon, once freed, will slip through the slot on the lower right that it is routed through.. Now, at this point, other than maybe a miscellaneous piece of tape somewhere on the back - there is nothing physically holding the LCD in place - it can potentially fall out through the front and hang by it's wiring. Again referring to the original post, top image, those 6-8 thin wires running from the copper heat sink on the top, run to the connector on the bottom that plugs into the LCD. Removing that tape that covers that connector and gently prying out the connector frees the LCD. Without the Digitizer protecting it, the front of the LCD is relatively soft and susceptible to damage - so be careful.

LCD is a unit and really easy to replace in my opinion.. Putting the digitizer on afterwards and sticking it in place and plugging it in without excessively flexing the ribbon cable presents the challenge in my opinion..

Good Luck..
[Transformer TF300T General] Stempanssi:
Thank you very much... But sorry if i`m asking too much: I still don`t get what you mean with the bezel? Do you mean the black "edge" surrounding the glass, which also says ASUS?

Cause that and the glass comes already together when buying a digitizer.
[Transformer TF300T General] graphdarnell:
The digitizer is one piece of glass entirely. It has "Asus" printed on it. The bezel is a separate piece of black plastic frame which surrounds the outer edge of the digitizer. Once you've removed the thing, you'd know what we're talking about here. Time permitting, I will post a pic later.

---------- Post added at 07:56 PM ---------- Previous post was at 07:50 PM ----------

What are you trying to replace anyway, Stempanssi? If your digitizer is intact you don't need to worry about the bezel. Just be extremely careful when scraping the lcd off the digitizer. It doesn't take much to crack. Removing the bezel is unnecessary in this case, and unwise.
[Transformer TF300T General] Stempanssi:
Ahaa. Now I got it... :)

I am trying to replace my cracked digitizer. (Touch not working).

How have other people on the internet done this so easily :confused:
[Transformer TF300T General] graphdarnell:
adhesive

Turns out that none of the tapes I was able to get my hands on would work. Not even that which would hold 10 lbs. Stronger tapes would be either too thick or too expensive. I'm experimenting with a gel glue that takes 24 hrs to cure. If it pans out, I'll post the results and the brand.
[Transformer TF300T General] Stempanssi:
Oh what a PITA that digitizer was. :mad:

But I got the bezel resting there and now I do see what you guys are talking about...

Does it have to be double sided tape? How about real sticky glass glue? I know it doesn´t cover all parts of the bezel...

And is it possible to test the LCD incase of damage without the digitizer?
[Transformer TF300T General] graphdarnell:
I don't think you need the digiizer to light up the lcd.
[Transformer TF300T General] mabretske:
Been there, done that.. The tablet will work just fine w/o touch-screen operation provided you didn't break it during the process.. Mine has taken quite a beating - trust me.. Still ticking so far..

** Note: After further examination, it appears that a better approach 2nd time around would be to use the doublesided foam tape to adhere the digitizer to the LCD and then insert the LCD/Digitizer into the tablet as one assembly; perhaps... I keep running across fleeting posts here and there that people are buying it this way - as an assembled unit.. The frame to the LCD matches pretty much perfectly with the embedded touchscreen connections in the glass; once the two are mated you can stop being concerned with anything getting dusty or smudged.

Alas, I may never get that far.. Getting a bit of pushback from the digitizer seller on Amazon at the moment re:RMA..

Stay Tuned..
[Transformer TF300T General] Stempanssi:
Why do everybody keep saying that they are adhering the digitizer to the lcd?

I was able to lift off the lcd completely from the frame without any adhesive...

I know it is different with the digitizer and frame(bezel).
[Transformer TF300T General] mabretske:
Because on ours, at least mine - the digitizer was fastened to both the bezel and the LCD.. Fastened to the bezel with thin doublesided sticky tape about a half inch wide and fastened to the LCD with doublesided sticky foam tape about 2mm wide but thicker..

Are you telling me/us yours was different?
[Transformer TF300T General] graphdarnell:
I think I know what Stempanssi is talking about. If you need not replace the Digitizer, one can just unclip the lcd's back frame from its front frame. That done, you can then carefully lift the lcd out; or you can flip the device on its back and the lcd would fall out. This, however, cannot be done if you have to replace just the Digitizer while keeping the old lcd. Then, one needs to remove its front frame and reuse it on the new Digitizer.
[Transformer TF300T General] Stempanssi:
That is just what I have done, but are you saying that I have to remove the front frame with the clips also from the old digitizer.

I am replacing digitizer only...
[Transformer TF300T General] graphdarnell:
The front frame is held onto the Digitizer by means of double-sided tape. You have to remove it from the old dig to reuse it on the new one. Basically you have to scrape it off the old dig. But once the lcd itself is out, you're safe as the front frame is metal and you can't damage it beyond salvage unless you use excessive and brute force. The front plastic bezel for the dig is another story altogether. It's soft so you might bend it out of shape, and finding the appropriate adhesive can be a challenge 'cause you don't want to bond it permanently.

Edit: If going about it turns out to be a challenge for you then, depending on where you are, I can send you both lcd frames that I took out on mine. I have no use for them anymore. It's a gift evidently, if you're willing to pay for shipping.
[Transformer TF300T General] Stempanssi:
There is my pieces. As for the metal frame on that digitizer, so I am supposed to remove that?

But you said you don't need your parts, why?

I live in Finland, but I don't know if it is necessary for me. But I'll see. Thanks anyways.
[Transformer TF300T General] graphdarnell:
How are you gonna hold the lcd in place without the frames? It's just a piece of glass in front and a soft display in the back. You apply any kind of force on it without the frames, you might damage or crack it. I bought a new lcd that came with frames. The old one is completely shot from impact. So I have the extra (old) frames for anybody who can use them. But since you're in Finland I assume it's more economical to try and remove the front frame carefully so you can reuse it. Good luck, and let us know how it turns out.
[Transformer TF300T General] Stempanssi:
Yea.

I was just thinking that it would have been the most convenient and logical solution if the digitizer had that frame already...

But I will post further info...
[Transformer TF300T General] mabretske:
LCD Frame

Wow guys - didn't even know the 'frame" came off of the LCD.. Went and looked at mine again after checking out your photos.. Would never even think of separating the two.. Thought it was fabricated that way. That would be where the double-sided sticky foam goes.. Between the frame and the digitizer (and the LCD snaps into the frame evidently).

Anyway, they appear pretty integral to one another. Taking brain surgery to a new level eh?

---------- Post added at 06:26 AM ---------- Previous post was at 06:13 AM ----------

Stempanssi, I pulled the LCD and Frame from the digitizer as one unit, and will be reassembling them onto the replacement digitizer as one unit (didn't even know they separated). As Graphdarnell stated, yer gonna need to pull that frame off the digitizer. Certainly less wait time than trying to get one shipped; would be surprised if you could even buy one separately.

Graphdarnell, looks like that frame would be wobbly w/o the LCD inside to stabilize it, no?

Perhaps Stempanssi should snap the LCD back into it prior to attempting removal from the digitizer?
[Transformer TF300T General] Stempanssi:
Removing the LCD from the frame before uninstalling digitizer made the work unrisky due to not having to be afraid is the LCD gonna break.

But as you stated I also started to think that the frame is REALLY "wobbly", it bends if I press it just too hard. Would this make it impossible to separate the frame from the dig without the LCD?

But Mabretske, what did you replace and have you succeeded?
[Transformer TF300T General] graphdarnell:
Theoretically, it can be done without the lcd in place. Actually I've seen someone do it that way. If you use an exacto knife with a thin blade

as I did, it should come off clean. The tape used on the lcd is not as bad as the one on the bezel. I didn't have to save the lcd, so I removed the whole thing that way, but I didn't see or feel further breakage while doing it. Just be careful with the force applied.
[Transformer TF300T General] mabretske:
Successful vs. Unsuccessful

Stempanssi, My new digitizer was bad (or I screwed up the ribbon cable). In other words - unsuccessful.. I have another on the way as of today under warranty RA. Now I'm faced with the problem of what to use for the two different types of tapes.

Graphdarnell, was your ribbon cable tempermental at all. Any trouble with insertion into the headers? Did you just get it the first time and were good to go?
[Transformer TF300T General] graphdarnell:
Ur question is kind of unclear to me. For the LCD, I used the 3M sticker 2mm sold on ebay for a couple of bucks. I still have plenty left. It's a pity you're way down under. On the bezel I used Loctite Stik'N Seal outdoor adhesive bought at Home Depot. They both seem to hold pretty well. Loctite is good in my opinion as it remains semi-flex after curing. As to the Dig's two-pronged ribbon, I found out the best way would be to unscrew (3 screws) the daughter board, hold it up at an angle while inserting the cables. That position gives you a leverage to push them in without bending them excessively. This is easily done when they go straight in. I can tell by the white markings that they fit all the way in without too much effort. Thereafter, just press down the latches.

As for the rest, I found out that the cable slot at the other end going to the Main Board was damaged. Thus, I can't get seat the silver flat cable properly. The sd slot works, but not the touchscreen. Not yet anyway. Still hunting for the daughter board.

BTW, does anybody know if the device can be used with a dock (keyboard) without a functional touchscreen? I don't have one so I don't know. Can someone enlighten me?
[Transformer TF300T General] mabretske:
tape

That answered my question.. Thanks..

Just got this for the LCD - http://www.amazon.com/Adhesive-Sticker-Digitizer-Supersonic-Incredible/dp/B004WIQW3U/ref=lh_ni_t

Seems like what you were describing.

Thinking of this for the bezel - http://solutions.3m.com/wps/portal/...3Cgs_6C8GSGCWB2_N2RL3FHWVK_GPD0K8BC31gv)&rt=d

What did any of you use to remove remaining adhesive from the bezel?
[Transformer TF300T General] graphdarnell:
Goo-gone, my man. Pay heed to this. The bezel adhesive is a plastic strip with adhesive on both sides, as you know. When you scrape the dig off it, most likely you'd be cutting through the stickies on the the dig's side. The other side (and the strip) still sticks to the bezel. If you can clean the adhesive just on the dig's side, do it without touching the adhesive on the other side. The reason I said this is that given your record (LOL), you might need to unglue the thing again. If you remove the plastic strip and apply the new adhesive directly onto the bezel, I figure it'd be a pain later on.

Smear the exposed surface of the plastic strip with a generous amount of goo-gone, let it soak for 1/2 hr, then clean it with a towel - something with grit, but not too abrasive. Then clean it again with alcohol of at least 91%, as Goo-gone would leave an oily film on the strip, which prevents the new adhesive from setting.
[Transformer TF300T General] Stempanssi:
Yes. My thoughts are that if I could fix this with approx. 70bucks i would get a working tablet.

But what comes to buying a new tablet I would like to have one now but on the other want to wait for a good price/quality tablet as for this time being android tablets aren't as shall we say good as an ipad. No I am not a apple fanboy, but you got to say that the ipad is more convenient in basic tasks such as gaming and browsing.

I don't want to buy a new one now. I will wait for newer inventions.

As for this pad, one could make it run without a dig. Using it with a mouse. I don't see any reason why it wouldn't work.
[Transformer TF300T General] tandynor:
Did you order one? I was able to order one ans im still waiting for it to come in the mail. hopefully it comes in today. I babied my tablet. its never dropped on the ground or anything, always in its leather case. I just went to use it and the touchscreen would not respond. Im hoping the TS board fixes the problem. if not im parting this POS out on ebay LOL! I dont think ill buy a tablet from Asus next time, and if I do ill be damn sure to get the warranty from where ever I buy it from LOL.

on youtube, there are a few vids where people are on their 2nd return from ASUS and the touch screen still does not work. So I dont know what the problem might be.
[Transformer TF300T General] Agred:
Wow. I always wanted to check what it is below the cover. Thanks chili_red for sharing the photos. Wasn't there any plugs that would break so ASUS would know that someone opened it? And does someone knows if I can replace RAM for bigger one? :)
[Transformer TF300T General] graphdarnell:
I left it with a friend to make sure it's the TS board that went bad. By the time I got it back they were all gone. Which means there's a big demand for them, e.g., they are failing in droves. As you say, 2 returns and the problem didn't get fixed. Even if the Asus technicians are too poorly trained to pinpoint the root cause, replacing a well constructed component should do. That a new board still exhibits old symptoms signifies either it's faulty by design, or there's a black hole in the manufacturing process - definitely something a consumer can't be burdened with. You know, the more I talk about this, the more I am tempted with a class action against Asus. It's looks trivial now, but we shouldn't set a bad precedent ever.

@Tandynor: Don't forget to share your progress with us once you receive the part from Ebay.

@Agred: When you open the device, do not break the yellow seal on the copper pad covering most of the mainboard. And use latex gloves so as not to leave fingerprints all over the place. Asus has no access to the government data base, so it wouldn't know they are yours (LOL) but the sight would be un-hygienic (chuckles). Otherwise, unless you have the precision skills of a robot, you can't increase the ram amount as the chips are soldered to the motherboard.
[Transformer TF300T General] tandynor:
Good news to report! the TS BOARD DID fix the problem :). Touch screen is working again. Im about to put the case back on and do some final testing, but I think that is the culprit. all is good! I repeat all is good! :cool::eek::highfive:
[Transformer TF300T General] milu_m:
Yes, the device may be used with unplugged digitizer. I'm using it that way while waiting for new digitizer. As th old one is broken, probably because of wrong insertion into dock or Asus mistake while designing the device.
[Transformer TF300T General] pendragon11:
i'm looking to swap out a cracked lcd, which hopefully is easier than the digitizer. got a few questions though:

is it possible to swap the lcd wthout messing with the digitizer, and double sided tape, at all? i can just pull it from the "frame" that the digi is glued/taped to?

if touch works perfectly but the lcd is visibly damaged is it worth opening the unit prematurely to inspect the digi?

also, does anyone know if these ones are legit?:

http://www.mylcdtouchscreen.com/asu...d-screen-display-panel-replacement_p1085.html or any other lcd recommendations?

thanks for the help, i've been distraught without my little tabby tabs
[Transformer TF300T General] graphdarnell:
If you look at earlier posts by stempanssi and me, we discussed that procedure at length. Short answer: yes. Snap the lcd back frame off, then lift or fish the lcd out with some kind of hook. Better yet, turn the tablet upside down, it will fall out.

Why do you have to inspect the digi if there's no visible damage to it?

As to the buying the replacement, I've never dealt with that store you provided the link to, but I know laptopscreen.com in Seattle/Vancouver is legit, except that they're out of stock right now and charge $17.00 for shipping. Just recently, I bought from chinaphoneaccessories on Ebay. Everything went smooth with these guys, LCD is about $72.00 with free shipping. You have to give it a week before it gets to the US. Don't know about other continents.

Let me know if any questions.

---------- Post added at 03:26 AM ---------- Previous post was at 03:06 AM ----------

Hey tandynor. :good: Now that you've accomplished the mission, I have a favor to ask. If your silver flat cable is not too messed up, would you care to sell it to me? Mine is totally twisted from numerous pullings. Though I am inclined to think it's the board, I don't want to leave any stone unturned, if anything, for the benefits of those who come after. Thanks. Ur located in the US right?
[Transformer TF300T General] tandynor:
sure ill send it to you for free for the Cause of figuring this crap out! :p I doubt its the cable though. cause my cable was perfect, as was your before you started messing with it, but you never know. I diddnt try with the old cable, but this board wast brand new. The Reset button on the TS board I got had pin holes on the button like someone must have been trying to reset their tablet before using a needle. PM me your address. im in texas. :cowboy:
[Transformer TF300T General] graphdarnell:
Just PM you. If you don't receive it, please let me know. Now onward to the intriguing part. You said yout TS board was brand new, yet someone poked a needle into some part? And this board has a friggin' Reset button!!?? I must have missed this part somehow. Could you elaborate, or better yet, illustrate with a pic of where on the board? This is getting interesting.

PS: my cable went bust at a couple of places the first time I yanked it out. Didn't know better. That's why.
[Transformer TF300T General] pendragon11:
Sweet. Yeah, I thought from reading your posts that that may be the case, but I just wanted to ask outright. This thread is great. Also. I considered popping the unit open to look at the digi because i just wanted to be certain damage was restricted to the lcd. Would a cracked digi work at all? as of now, i have a black chunk taken out of the bottom right of the screen with cracks of yellow radiating from it, but touch appears to be fine in that area. suppose i should get an app to test that. just would've expected a hit that could damage the lcd to also damage the digi.

As for buying, thanks for the tips. I actually live in seattle (queen anne) so maybe i can dodge a shipping fee. I have to wait until another paycheck before I can act though, no holiday pay really put me in a bind.

thanks again for the informative thread
[Transformer TF300T General] graphdarnell:
If the touchscreen is working, I'd suggest that you leave the device off for the time being. As I have observed, there's no telling how turning the unit on might affect the interacting between the lcd and the display circuitry on the mainboard. I've seen such circuitry get fried just because some silly user insisted on using a laptop (you guessed it: fruit company) with a broken lcd.

If you happen to have the device open, do not remove the copper pad and break the seal. All you have to do is disconnect (1) the lcd cable running across the battery at the lcd's end; and (2) the touchscreen two-pronged amber ribbon cable. Then remove all the tiny screws around the frame of the mainboard and battery. Take macro pictures so you know what goes where. Then gently lift the whole frame and slide it out at the amber cable area without pinching or twisting it. What's left is just the lcd and digi.

As to the touchscreen, it'd suffice to inspect it visually from the front side. If you're gonna replace the lcd anyway, once it's out, you can inspect from the back of the TS as well. I wouldn't turn it on right now. It doesn't help further diagnostics, only begs for hazards. Patience, my man. Good luck.
[Transformer TF300T General] tandynor:
I think these were taken out of used working tablets. they were not new. not advertised as new. but yeah right next to the mini sd card slot is the little Reset hole. you have to stick a pin in there to reset the tablet. the TS Board has the Sdcard slot and the reset button on the board aas well as the 2 connectors for the digitizer, and one connector that goes to the main motherboard. . :cyclops:
[Transformer TF300T General] graphdarnell:
reset button

Is that with the red circle the reset button?

Edit: Never mind. You were talking about the reset switch for the whole thing. I thought there was a separate reset for just the TS Board. I removed the pic.
[Transformer TF300T General] milu_m:
Thanks to this description I was able to replace my broken digitizer with much less problems than I thought. One thing to add. If you happen to replace just digitizer you may save existing digitizer tape. Just use some knife/blade to pry the tape from glass and slowly take away that plastic frame from digitizer. I couldn't save the lcd tape but there might be possibility to keep it.
[Transformer TF300T General] Stempanssi:
What is this "film" underneath the glass. I assume it is a part of the digitizer. You can see it popping up a bit in the pic.
[Transformer TF300T General] milu_m:
I think that this plastic is main part of the digitizer. It's just over the clear part of the screen and it's connected to the stripe which you connect into board.

[Transformer TF300T General] Stempanssi:
Yea, I took the shot and pryed it off. Now I got the frame separate and old dig in the trash.

So now only thing left is to order a new dig.

At which propability do you think my TS board may have broke? And do you think random touches is due to faulty TS board or dig, as I had random touches in the upper left corner every now and then?
