I had random touches too. They made me to open the back cover and disconnect digitizer to just use keyboard as my screen was fine. After replacing digitizer everything is finally as it should be. So until you connect new digitizer to the board you have 50% chance that ts board is fine ;) From mine case I can say that it should be ok and just put your new digitizer screen and will be OK.

50% :eek:

Okay but I figured out that because of the crack, the screen pressed randomly everywhere on the screen and therefore I think the TS board is not faulty as otherwise it would not have registered those touches, OR?
[Transformer TF300T General] milu_m:
I don't know the internals of the ts board but I suspect that it's fine. As I wrote before I had the same problems with random touches and at the end it was just broken digitizer. So in your case out should be similar.

[Transformer TF300T General] graphdarnell:
"They made me open the back cover..." Who's they exactly milu? And did they explain to you why you'd have to disconnect the digitizer? Something like, "it would damage the TS board if you keep on using the fragmented digitizer...etc.", perhaps?
[Transformer TF300T General] milu_m:
No, no, they == random touches. :)

Tablet was in keyboard dock and it was unusable because of that. After disconnecting digitizer I could use keyboard dock without a problem.
[Transformer TF300T General] Stempanssi:
Hey guys do you think this seems legit? (I know it is finnish but...).

It says free shipping... Which of the digitizers did you buy? I assume you bought from ebay...

[Transformer TF300T General] pendragon11:
just a quick note: be sure to remove the back from around the screen (including the sides), not the back with the etchings on it. nothing a little glue and determination can't fix but my back is now in two pieces and one has some broken connectors... facepalm. anyone have an extra?

sometimes, strangely, when you do something embarrassing that no one witnesses, you get the urge to tell everyone
[Transformer TF300T General] graphdarnell:
Have no idea what you're talking about. What etchings? A picture would be worth a thousand words. Is it the touch screen itself, because AFAIK only the LCD and the TS would have connectors.
[Transformer TF300T General] pendragon11:
Simple (like a moron) messed up opening my 300. Rather than properly remove the entire back cover, I removed the, shall we say, second back cover. This is the area with the rounded design on the back of your tablet. It can be separated from the back mount .U

Unfortunately, on my tablet, the are with the design was loose, rather than the whole mount, so I messed up.

Again, when taking off the back of the tablet (1st step to any repair) , make sure you remove the bezel including the volume and power switches. Also, as stated in the op, remove any micro sd beforehand

There's my thousand words. Unfortunately I already glued it back together. Wasn't hard, really I just followed asus's glue lines.

I'm going to swap out my LCD in the coming days, I'll make a photo guide as best I can.
[Transformer TF300T General] MadBastard:
Im waiting for my LCD too,but iam little bit scared to change it by myself ..:D .any photo or video guide will make me and other users happy :) .

Nie pękaj ;P

Don't be scared use graphdarnell's instructions: http://xdaforums.com/showthread.php?p=36346639

1. Remove plastic bezel with back cover not just back cover.

2. Unplug digitizer(look thoroughly how to do it: gently pry right side of the connector. It's opposite to inserting cable) and unplug LCD display cable.

3. Remove screws that keeps magnesium frame+mainboard with LCD and digitizer frame. Mainly silver tiny screws and one little larger black in my case. Remove black battery screws(I'm not sure if that was necessary) Don't remove dock connector and dock metal details(not necessary - 6 screws less to unscrew)

4. If you removed all screws that are keeping magnesium frame with front frame then it should be easy to separate them. Keep eye on digitizer stripe and LCD cable.

5. Do the rest then assemble and remember to take cold beer or drink at the end ;P

[Transformer TF300T General] pendragon11:
I was under the impression that the LCD could be replaced without unplugging the digi and by simply pulling the digi lcd from the frame. Could be mistaken. LCD arrives today so I'm going to attempt a repair tonight
[Transformer TF300T General] pendragon11:
installing the lcd was a failure. the procedure went well (opened the lcd frame, swapped them out), but the replacement screen was cracked. after much dillydaddling, now no screen will work on it at all. and after keeping the digi wire in for so long while swapping lcds, that has finally worn out, so i am out 2 screens and one digitizer.... aka, bye guys, it's been nice doing this. I'll be back in a year or two. in the meantime, i'm being laid off and can't play this game any more. such a bummer, i treasured my tf...

That all being said: I think my method of installation was solid, and I will upload pics of what I did shortly (without my 300 I don't have an SD reader)
[Transformer TF300T General] MadBastard:

How many of you turned the on/off switch to off before doing anything?

Does it matter as I didn't? :rolleyes:
[Transformer TF300T General] milu_m:
This guide is OK. Though I have one doubt. This guy removes LCD from metal frame but I haven't seen if he dismounts it from old digitizer to put it back to LCD and then assemble it together with the display.

So have you ever found out what caused this problem? Hopefully it's just loose solder. Otherwise a jack can certainly be replaced, but where do you go for new parts?
[Transformer TF300T General] Tamaskan:
Does anyone knows how many mAh the battery is?
[Transformer TF300T General] graphdarnell:
WTH guy! We all cautioned you to go about it gingerly. What a waste. Had I guessed, I could've helped you with it for a beer, seriously! It must be a loose or incorrect connection somewhere with the lcd, 'cause as you said before, it would show something even when broken. Mine for instance displayed garbage on the right half of the screen that had two or three crack lines across its width before replacement.

So don't lose faith people. Sometimes it takes a few tries before you get it right.

Hopefully, everything is not lost, Pendragon. There are still good parts in that machine, so when you have the means again, you can give it another try. Or if you decide to part it out, you know lots of people would need those good parts right here. Sort of salvage what you can while helping others. Sorry to hear.
[Transformer TF300T General] pendragon11:
I'm going to try for money back on the bust lcd, but I'm reluctant to put anymore money into this... Lcd and digi combined cost a pretty penny and wouldn't guarantee success... Might as well wait a generation and buy a next generation model

[Transformer TF300T General] milu_m:
I turned it off before doing anything but haven't disconnected the battery. I don't know what impact would be not turning off.
[Transformer TF300T General] tandynor:
well you could short something out by accident by having the battery plugged in. I have experienced shorting Laptops out while working with the battery plugged in even though its not powered on.
[Transformer TF300T General] NJ_RAMS_FAN:
How easy is it to remove the gold plate covering the charging flex cable? One of my sis-in-laws ask me to replace her since the whole port was ripped part when her daughter pull the tablet while charging.. does it bend easily? I don't have the tablet with me to try. :)
[Transformer TF300T General] mabretske:
2nd Digitizer

Recap: Dropped and shattered digitizer.. System charges, has video, sound, G-sense, wifi, everything works as far as I can tell - no touch response.

Replaced Digitizer - no go.. Pulled the digitizer out while still connected and hovering over the system and it responded once, briefly. Assumed that digi cable was bad or digi DOA. Razzed vendor for a replacement.

Just replaced 2nd digi.. It went so really really smooth.. No problems. Nothing to even think might be an issue.. Reassembled unit; looks and feels brand new.. Still nothing!!! Mothur F*#^$@ !!!!

Opened back again to try to handle connections while powered up for some hope based on the history - and the battery died.. Charging - will check it out again in the morning..

So, Hey you guys.. I have heard some of you talk about this daughter board, that the digi plugs into.. How do you undo the cable that comes out of that to the main board? Would like to reseat it, but it doesn't seem to want to come out..
[Transformer TF300T General] mabretske:
Follow

So, now I guess I've got/had the same problem.. One item of note.. The 1st replacement digi was a 69.10I21.G01, this 2nd one is a .G03.. The seller did want to know what my original was prior to shipping out the 2nd.. But I told them it was in shards and had been tossed some time ago.

Curious now if there is a compatibility issue?

Regarding your TS board; does the unit sense the SD card? If so, the cable is probably good.. I can't test mine because it has been factory reset and wants to go through initial setup before it will do anything..

---------- Post added at 11:17 PM ---------- Previous post was at 10:40 PM ----------

And another thing.. Has anyone who replaced the digitizer only to find that it doesn't work attempted to use the unit with a keyboard?? Thinking of buying one just so the thing isn't a freaking door stop..

Don't see any reason why it wouldn't - but apprehensive as to whether or not you can get through the original setup after a factory reset with a keyboard..

Thoughts???
[Transformer TF300T General] graphdarnell:
The SD card in mine works fine which, as you said, indicates the cable is seated correctly. But if you want to reseat it on the daughter board, use a thin flat-blade knife to gently lift the black tab opposite the white connector (where the cable is inserted) to 90% (rear edge pointing up), then pull the cable straight out. I always do this with the board unscrewed so I can pull out without stressing the cable. Be careful when you reinsert it as too much force wrongly applied will bend the pins of the connector or shave the metal ends off the cable. If you do it at the right angle, it should go in without problem.

I borrow a keyboard and everything goes ok except for the touchscreen. Thus you don't need a functional digi. As I said, one might be inclined to fault the new digitizer, reading from the "expert's" experience quoted above, but I seriously question that statement - 33% failure rate??? Especially in your case where you have replaced the thing twice. What are the chances of 2 in a row?!

Additional inf

o: While you're without a keyboard, one way to check the SD card slot if you have CWM installed is to have a file, any file, on an SD card, boot into recovery and select "install from sd card"/"select file from sd card". If the file shows, it means the card is being recognized and read. If it sees the card but returns "the folder is empty" then it's not.
[Transformer TF300T General] mabretske:
CWM

I don't have cwm.. But there might be some sd card access from the OEM version of bios/bootloader.. I'll check that.. Good thinking. I really don't expect there to be a problem. Everything else in this unit has been so solid considering what it has been through. The video connector, audio connector, volume and power buttons, charge connector.. Except for the fact that the digi can't take a hit, its all been pretty solid.

Here's my current line of thinking - and perhaps you could validate with your borrowed keyboard..

If there is different hardware (ie: different part numbers on the digi's) perhaps upgraded firmware will be necessary in order for the touch scanning for the digi to properly operate with the new hardware. Compensation for different latency, etc,,.. Something that might be easy enough for you to investigate since you have a keyboard handy.
[Transformer TF300T General] graphdarnell:
If that's your theory, then you should flash the latest android OS available for the TF300. Kaputt digi don't obstruct that. I really believe it's hardware stuff, though not the digi. Otherwise, the newest firmware should always be backwardly compatible to accommodate all versions of hardware up to its release time. Mine is just that and it doesn't solve ze probleme!
[Transformer TF300T General] Stempanssi:
Just ordered a dig from ebay.

We'll see the result after max (was it) 16 days, I don't remember but anyways...
[Transformer TF300T General] mabretske:
Asus seems to be making a killing on digitizers............ :eek:
[Transformer TF300T General] mabretske:
I would be interested in knowing what the part number is on the ribbon cable of your current digitizer if it's not too much trouble.. :D
[Transformer TF300T General] Stempanssi:
Ok. I looked at my old ribbon cable but it did not say anything like GO1 or 2 or 3. But we'll see. I will report back...
[Transformer TF300T General] graphdarnell:
Quick question for all of us: you successfully installed a new TS board. Did you have to disconnect the battery and/or wait for the MB to discharge before connecting the TS board? It's true as I said before that a broken LCD could screw up the circuitry if you leave a laptop powered on, but I have no personal experience regarding the Dig doing the same thing on a tablet.
[Transformer TF300T General] rickavers42:
Simple

It's actually very easy to lift the heat sink. Just be careful not to rip your warranty void sticker there. It's a nice little chip with Nvidia printed on it. I couldn't believe such a thin piece of copper could be so thermally efficient for heat dissipation.
[Transformer TF300T General] tandynor:
I probably didnt have too, but I did it just in case. Only cause I noticed that when I was messing around with the Old TS board before finding this thread, was that if you unscrew the TS board and have it powered on and then try to put the TS board back in to place to screw it back down, the Tablet will Turn off. like its shorting out touching the frame or whatever.
[Transformer TF300T General] graphdarnell:
I can't pinpoint anything definite between the connected battery and the dismantling of the touchscreen - including the touchscreen, the TS board and the cables. But given the high rate of failure after people try to replace the touchscreen and reconnect the TS board with the battery connected, I'd surmise that this whole thing is sensitive to any current fed to it. You could have inadvertently damaged the TS board when you first "messed around" with it while the battery was plugged in, tandynor.

Thus, to err on the safe side, disconnect the battery FIRST before doing anything! After replacing the screen(s), when everything else is in place, it should be the LAST thing you reconnect before putting back the copper pad. If you're still under warranty, find a way to totally discharge the damn thing before touching anything related to the touchscreen. I say "find the way" 'cause it's not safe if the LCD is broken to leave it lit up as it might screw the display circuitry. Perhaps you should have it off, open the back and disconnect the LCD cable at the LCD's end, then turn it on until the battery runs dry.

I did what I preach here with a loaned TS board, and when it's finished, the first thing the tablet did was updating the firmware for the touchscreen. Had I had the battery plugged in, it could have done that while I was doing something, and the off-and-on contact could have screwed the whole thing, not unlike what happens when the current is cut off (battery gets drained) in the middle of flashing roms.
[Transformer TF300T General] Stempanssi:
I reaaaally do hope my TS is not broken. I have only disconnected everything, not connected. I neither had it turned off from the switch nor removed battery. I now have i turned off but do you think I should disconnect battery?
[Transformer TF300T General] Stempanssi:
Picked up my dig from the post office, but I'm now at our cabin so installing will go to sunday. BTW. It says GO1.

One thing that bothers me is the fact that this doesn't look much like the original. No such text on the ribbon cable and the Asus logo seems smaller ( don't have the original over here).
[Transformer TF300T General] graphdarnell:
I personally don't think what version of the digi should matter. And I don't believe that red herring about new digs failing en masse. Except that the ribbon is fragile in the green area (between the amber part and the dig itself). You can easily rend it with a slight motion in the wrong direction. It has some flexibility but don't take abuse well. Hold the TS board at an angle to insert the ribbon straight in, outside prong first.

Back to the battery. I think we should disconnect it before doing anything, just to be safe. You can risk it, but it would be unnecessary. If your tablet is still under warranty and you don't want to break the seal, then somehow drain it completely first. If your dig is cracked, perhaps you should disconnect the amber ribbon before powering the device on to discharge the battery. Being deprived of the tablet's use for a couple of days is much better than having to fork out more dough for the boards, not to mention its unavailability.

Technically, you're not hoodwinking, since the TS board lies outside the copper pad. I'd say the part covered by the pad is not meant to be tampered with as evidenced by the seal; but everything else is touchable.

BTW, I found out what went wrong with the headphone jack too. Mine was only working on the right side. Now it's stereo again. If anyone has the same problem, I'd be glad to share what I know.
[Transformer TF300T General] Stempanssi:
I have already broke the seal but if I remove the plate, where do I get that glue or sticker which holds it in place? Or is it sturdy enough to handle a second glueing
[Transformer TF300T General] graphdarnell:
What I did was I cleaned the copper spot and top of the CPU with acetone and 91% alcohol. Then I applied crushed diamond thermal paste to both surfaces, the ram above the CPU, put quality double-sided tape at spots where they used to have stickers (at inside left and right edges of the pad), and press the pad back. When you snap the cover in, it would hold the pad in place. If you feel insecure, stick a few patches of aluminum foil tape around the copper pad. Alternatively, you can use sticky thermal pads.
[Transformer TF300T General] graphdarnell:
Pendragon11 if you're reading this, I have a suggestion for you: you should test your device to determine what's still good and what not. You can leave the LCD and Dig cables unplugged, use a micro HDMI cable or adapter (can be bought on Ebay for a couple of bucks) to hook the thing to a tv. If you power it on and the tv shows booting, then the MB and display circuit obviously are still intact.

The touchscreen, on the other hand, requires a working dig which you don't have. I know a person down here who has an extra dig for around 60. So if you ever head this way for a vacation or something, we can find out. Heck, we can even try it on my machine. If your board's dead, it must have happened sometime during the replacement process. Should that confirm my guess earlier, then it's not Asus's fault. We just have to be more cautious in the future. Steep price, but at least those who come after get to learn from our mistake.
[Transformer TF300T General] godutch:
my gf broke the the LCD and digitizer, does anyone know how much Asus charges for repair because from what I understand few people have been succesful in replacing them themselves, or do I stand a better chance with a digitizer LCD combo? the warranty seal already seems to have broken in the fall.
[Transformer TF300T General] mabretske:
So you got your touchscreen working with the borrowed T/S board? Because I'm there... Got the keyboard, setup the unit from scratch, updated all the firmware as well as lastest OS and everything that I couldn't test before works EXCEPT for the freaking touchscreen still! If the T/S Board is the fix at this point - I suppose I'd like to know where to get one, because even with a keyboard, this thing is severly handicapped without a touch function.
[Transformer TF300T General] graphdarnell:
You'd be better off buying a used one. I don't anticipate anything below $200.00. But with a little patience, you should be able to do it following all the advices in this thread. I did it, no big deal. Though to me, the fun is more in doing it, not in getting the end result. A combo would be hard to come by. I haven't seen one anywhere, except one place in Washington State but they were out of stock at the time. Try "laptopscreen.com". Putting the screens together is not that hard unless you're really clumsy. Just handle it the way you do your girlfriend. But you should follow the steps in strict order. Good luck.

---------- Post added at 08:43 PM ---------- Previous post was at 08:37 PM ----------

Yes M8t. You can get one here while they still have them:

http://www.ebay.com/itm/190784972545?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

Or you can wait a little. I might have a member send me one card to test. If it works, maybe you can convince the person to sell it to you. Either way, just remember to black it out before replacing the board.
[Transformer TF300T General] mabretske:
Awful nice of you to be testing stuff out for folks.. Sounds like you are putting your unit at risk everytime you do something like that? Also sounds like I have an extra digitizer.. I'll have to test it out once I get this thing working..
[Transformer TF300T General] graphdarnell:
I volunteered to test that board because I was looking for a working one when we talked. Also, I was curious whether having the unit plugged in while replacing the screens might trigger something negative. Doesn't appear coincidental lots of units going through replacement would go belly up afterwards. Seems not a lot of people think about detaching the battery when working on it. But apparently, the person hasn't gotten around to it. I would post the result if and when ascertained.
[Transformer TF300T General] Stempanssi:
I just put everything together but no!

It does NOT work. Fu*k.

I am now downloading latest asus firmware but what do you guys suggest me to do? My sdcard still works...
