Hehe, apparently, you're involved in the repair business, Vadim. Lots of people, myself included, are not. That's who I meant by "laypeople." Normally, when you're an insider to the repair industry, you'd have access to material sources like manufacturers or wholesale distributors who provide you with components unavailable to the general public. I'll look once more into the lcd to see if the backlight can be removed and reused without having to replace the whole assembly.

Technical question on the side: the board's ribbons are attached to the lcd itself by means of some adhesive, not solder, though I can't figure out what or how. Seems the touchscreen ribbon's also attached to the touchscreen the same way. It's not solder as it peels off too easily without tearing; and it's not glue since glue would inhibit continuity between the ribbon and the glass. It's certainly not conducive tracing that sticks as it dries out since that material would bridge parallel contact points. Now if you know and it's a trade secret then I wouldn't expect you to reveal it. Otherwise, please enlighten us. Thank you.

It's called "anisotropic conductive film" or ACF for short. Very expensive.

I'm not talking about reconnecting those connections. I mean to pull the lcd with the rebons and the electronics together.

Tearing or disconnecting that rebons result in dead lcd :(
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
I just took a closer look at the LCD assembly and found out that the backlight is separate from the lcd within the assembly. So I am restating what I said earlier: The backlight cannot be repaired, but a working one can be swapped onto a good lcd with a bad backlight to make it work again.

1. Picture 1 shows the row of leds (backlight). It is fused to the bottom (shiny) sheet of sheets stacked on top of the LCD back frame;

2. Picture 2 shows the back of the LCD assembly with the backlight connector, after the LCD itself and its board have been removed.

To remove the backlight, you need lay the LCD face down, and

1. Locate the connector shown in pic 2, at the lower left corner;

2. Use a flat, soft object to hold the connector down, then peel off the black plastic tape covering the electronic board to prevent it from pulling the connector up and tear it off;

3. Detach the connector from the electronic board;

4. Pry the electronic Board off the back by sliding a flat blade between them;

5. Remove the LCD front frame;

6. Remove the LCD with the attached electronic board;

7. Remove all the sheets underneath until you get to the bottom one;

8. Pry loose the white plastic frame lining the metal back frame and lift it off;

9. Remove the backlight sheet.

Personally, I don't think it's worth the effort. However, I have an extra backframe with the backlight working at the time I replaced the cracked LCD. Anyone in the US who has a backlight problem, doesn't want to spend $50 on a new LCD, and would like to try their hand at it, can have mine if they pay for shipping, unless it's no more than a couple of bucks. Just let me know.
[Transformer TF300T Q&A, Help & Troubleshooting] vadimbrk:
This is what I meant by saying that you don't need to pull the led stripe itself. You only need to pull the LCD.

Ok I had to order a new lcd because the backlight ribbon cable was GONE! I have no idea what happened to it. So I get the lcd install it and the dig and it comes on. I bought my daughter another tf300 so I was going to use that one to flash the ts pcb. As soon as I install everything my wife walks in and says "Are you ready for this" and hands me the tablet. Well you would know the screen is cracked. The best part was it was in a case. Well so much for that. So I had the 4.1 bootloader with cm10.1. Pc was recognizing tablet but I was getting unauthorized in adb. I tried everything and couldn't get it. I installed the stock rom its rooted and usb debugging is on. now I cant get adb to work. It is showing up as mtp. If I try to update driver with the adb driver it says not compatible. Am I doing something wrong?

So i got this TS pcb from asusparts 60-OK0GTC1001-C01 but once installed it shows up as ELAN 0000-0000 and ive tried to flash the 3011-4820.ekt both via adb on pc (got that setup) and terminal on android (tried on 4.1.1 & 4.2.1 both rooted) but doesn't work I get error's, ive also checked the coil but it seems fine and the battery's seen as 0% at all time and will not charge. I'm not sure what am missing here, Please help

PS: my original tf300t was a 5158n system but i replaced the digitizer with g01 and now TS pcb 60-OK0GTC1001-C01
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
You've got to give more details than the above. For instance, what kind of errors?

1. Why did you have to change the TS PCB?

2. Did you follow the outlined procedure when replacing it?

3. Does "ADB devices" command return device id?

4. What does the tab do when you try to charge it? Does the orange light by the power button come on at all?

Fastest way for help is to post the whole PC screen when you try to flash the firmware. Barring some hardware malfunction, there's no reason why the combo you currently have wouldn't work.
[Transformer TF300T Q&A, Help & Troubleshooting] uw07:
Hi Graphdarnell, Thanks for the reply, I uploaded a text log of all the error's i get from the cmd -> adb.exe

1 -> the original TS PCB has ELAN-3021-7038 in Touch Panel Version & does not work with my G01 digitizer

2 -> yes.

3 -> yes.

4 -> It stays the same, asking to connect the charger whether the charger is connected or not.

Hey All,

I replaced the digitizer for my in brother-in-law but i can't get the screen to work. I read thru these pages but I can't find info I'm looking for. (Or I might have missed it) :) anyways, digitizer doesn't respond to my touches then out of nowhere, it starts working. I can use it for a few. Could it be a defective digitizer? Then if the tablet goes stand by, then I can't get it to work. any help appreciated.

Part G01 for old and new digitizer.
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
You must have missed that part of the discussion. Replacing a broken digitizer with a new one of the same model still requires that you reflash the firmware if you encounter intermittent unresponsiveness. Most of the time, the symptom is that it'd work for a short time, then stops completely.
[Transformer TF300T Q&A, Help & Troubleshooting] NJ_RAMS_FAN:
ha. yes, I went back and re-read almost all the pages and found I had to reflash. I noticed this tablet had a latest firmware update message. I don't think he ever updated so would that work? Or should I try to flash the one that's currently on the tablet? thanks for the help.
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
I've flashed the TS firmware with both 4.1 and 4.2 bootloaders without problems, though I don't remember which version of the 4.2 bootloader. There's a claim somewhere else that the latest 4.2 bootloader is different from previous ones. I certainly did not flash with the latest since it's done a while ago. But if you go back to anything below that which is included in the Flatline Image for NVFlash, you should be ok.

Motherboard swap

Hello There!

I had a brick on my tablet, so I had to change the motherboard. I managed to do it, it is working, I was vrey carefully following the guide on swap.

However, my tablet recognises no touch screen module, the version is elan 0000-0000

I read all the thread.I tried to reflash it (page 14), but flashing cannot success, error in read and write Either. I triple checked the connections, I cleaned the connectors with alcohol. I think the connectors are fine, As I can use my SD card slot.

I have the latest 4.2 stock rom rooted, I have a dock, so I could manipulate If I could reach the PCB.

Please help me! Any Ideas??

thanks!

Hi, the pcb i had was faulty, so i got it replaced, but you could try checking the coil first to see if it looks burnt, if not then you might need a new pcb

---------- Post added at 02:08 PM ---------- Previous post was at 02:00 PM ----------

ELAN-0000-0000 means that the Touch Screen PCB is not detected by the motherboard (no connection) but that aside which motherboard model did you get?, is it the same as your previous one? & do you have a new TS pcb or is it the same one that was with the original tab before the replaced motherboard?
[Transformer TF300T Q&A, Help & Troubleshooting] dpeti:
I have only changed the motherboard, the touch PCB and the panel is the same. Both motherboards are REV 1.3G, however the part number is not the same, as I had 32 gigs and the new one is only 16 gig.

No parts of the motherboard looks or smells burned. I dunno what could be the problem...

Please help me! thanks!
[Transformer TF300T Q&A, Help & Troubleshooting] uw07:
assuming the cables are properly connected [the two digitizer one's white line all the way in & the big cable fully fitted] which i think they are, there shouldn't be any reason why it wouldn't work, but it could be because it was originally part of an 32gb model but that's only the internal storage and has nothing to do with the TS PCB, assuming all the cables are connected properly, all the parts are compatible and it still isn't detected then I'm really not sure, but I'll try to contact asus today or tomorrow and ill let you know what they say. :)

Thank you, thank you very much! Please help me! :)

Waiting for your answer!
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
Check post #119 on page 12 for a picture of the coil location. It's right above the TS connector on the motherboard. But it's tiny, so you'd need a magnifying glass to detect it. The TS PCB rarely goes bad, and given that it was working before, there's no reason, unless something is wrong with the motherboard. Now, if you force the cables into the slots, there's a chance you might bend the pins. I just try to cover the basics since there can be so many possibilities.

Thank you very much for asking! I will obviously try to solve on my own first, not RMA. I made a research and there is no difference for TS PCB's regarding the motherboard storage space. If this would be the cause, then there would be 16 and 32 gig type PCB....

As far as I can see, the coil looks allright. On the weekend I will have my hands on a multimeter I will check both the coil and the connectors. I did not force them, the connector looks allright. Maybe the lead is broken somewhere, I dont know. Will see on the weekend.

What is the purpose of this little coil? Surge damping? Can I simply "bridge" it with a piece of wire in case it is wrong or corrupted?
[Transformer TF300T Q&A, Help & Troubleshooting] dpeti:
Picture of the coil...

I did compare it to the original motherboard and does not look the same :S I dont know, maybe broken. Can I swap the or easier to bridge it?

Sorry for the quality, Nexus 4 is not the best in MACRO :)

Will do a better shot on the weekend!
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
I looked at the pics and the coil seems intact. If you want to test it, turn off the service switch, and measure continuity at both ends of the coil. Better yet, test at farther points connected to both ends. Best thing is to use a voltmeter that beeps.

The flat cable though, doesn't look so good. You might want to inspect the bottom side of it at both ends with a loupe 5x or higher. Look at the metal contact strips. Make sure they do not peel from the mylar base. While you're at it, look inside the connectors of the MB and the TS PCB too. I inadvertently bent one pin inside the TS PCB that could be seen only with a jewelry monocle, and that was enough to screw up the touch operation. I've yet to find a heat gun noozle as suggested by Vadim to replace it.
[Transformer TF300T Q&A, Help & Troubleshooting] dpeti:
Thanks for the quick answer!

The flat cable is not even disconnected on the picture. You can only see the reflection of the connector. :o

Ok, I will check the continuity of the coil. If it is ok, I will check the flat cable ends and the continuity of it.

In case it is broken, is it ok to bridge the coil, as I've read before?
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
I know the flat cable is not disconnected. From the look of it though, it doesn't seem in good health. Hope I'm wrong. If the coil is burned, then yes, you can bridge it with a solder blob or a fine strand of copper wire.
[Transformer TF300T Q&A, Help & Troubleshooting] dpeti:
Hey there!

The problem was the coil. As I've told you, It didn't look so good. I did override it with some soldering and now I have my touch back! Actually, I am posting this with the onscreen keyboard using my TF touchscreen! :)

Help I cracked my tf300!!!

Hey guys I need some help, I somehow cracked my tf300 glass and after reading through 30 plus pages of this forum, I AM SO CONFUSED!

If you guys could help me figure this out (Im sure I missed something) get my tablet fixed. MY TABLET DOESNT REGISTER TOUCH!!!

I have 1 hairline crack in the bottom left hand corner (not sure how it got there). The crack is just below where the lcd is so not actually interfering with the view. Is turned on the "show touches" in developer options. Here is where this gets interesting it shows and registers touches in the bottom inch all the way across, about a quarter inch up the right side all the way up, and a 3inch wide 2 inch tall box that works in the bottom right corner. Like what in the world the rest of the screen is unusable. So this leads me to believe I just need to replace the digitizer and not the SD PCB. Is that right??? I really need my tablet to function as I use it for work instead of a laptop!

Bored firmware 4820??? works will all digitizers?

I have the blank digitizer with the white sticker and no model number.

I am rooted stock 4.2.1 Do I need to be on 4.1???d

I the dock and can navigate with it.

I am running TWRP Recovery.

Right now my touch panel version is

I need the Android SDK and ADB Drivers???

If you dont understand something I can clarify just ask

Thanks in advance guys YOU RULE!
[Transformer TF300T Q&A, Help & Troubleshooting] graphdarnell:
If your broken digitizer is busy "playing with itself" (ghost touches), it naturally would ignore your inputs. You don't need to replace the PCB, just the glass. AFAIK, 4820 works well with blank digitizers; and you don't need to be on 4.1 to flash it, though I've come across reports of snags with some custom roms. Be careful with replacing the thing. Don't forget to turn off the service prior to messing with the rest of it.

You need the adb drivers to push the firmware and flash it. Get the latest ones. You also need to be rooted. After installing the drivers, try "adb devices" command. If it returns a serial number, you're good to go.

another cracked screen

Hi guys,

I posted my problems in the main Q&A list, because I thought I have multiple problems, but the more I read, the more I'm thinking it's all to do with the cracked screen....

the original post:

I bought a used TF300TG about 6 months ago and was quite happy with it. But last weekend it got bumped to the floor (less than 1 foot) on it's lower-right hand corner and cracked the screen. The lcd looks fine but I've lost the digitizer, except for the occasional ghost movements.

Also the trackpad is behaving weird, the same as with a BT-mouse or USB-mouse attached: no clicks are registered...

Navigating the tablet is down to cursos keys on the dock?!

Asus quotes me a repair price estimate of € 220 which makes that road a no-go.

Diving into this site, I am very glad to find that DIY repair of the digitizer is feasible and that even the problems surrounding the digi-version seems to have a workaround. So far I gather that adding the appropriate SW will sort that problem, only this requires (at least?) root access.

So I start researching that avenue. Downloaded and tried Motochopper and CWM-rootkit but these do not seem to work.

When going into fastboot I notice the left icon is not a USB-icon, but a green square with RCK on it.

Starting that app the machine starts to update but fails, giving me a "dead Android" with a red warning triangle. A while later the machine reboots normally.

I tried flashing a previous stock rom, but failed. After reflashing 4.2.1 I now have 4 icons: RCK, Android, USB and Wipe.....

By the way, unlocking with the tool (V8) also doesn't work: the app installs fine and opens but I can't click anything to accept the license (mouse (USB or BT) clicks do not register).

My problem is therefore a whole stack of problems:

* how to unlock, if I really need that,

* how to root a TF300TG on 4.2.1

* which screen to buy? Current version is ELAN-3011-4822 (have not opened tablet yet!)

* does USB-problem (mouse) relate to cracked screen?

My thoughts now:

Replace screen with appropriate new one.

But then: how to update SW, root and/or unlock?

Any help is greatly appreciated!

Hi all,

I just want to thank you all for all the great info on this website.

My son had an accident with my TF300T and I had to replace the digitizer (5158N FPC-1), so I got a cheap G01 digitizer, replaced the digitizer (not easy but doable if you have patience) and followed this awesome post (tablet was already rooted): http://xdaforums.com/showpost.php?p=39371862&postcount=104

The TF300T was up and running again.

After a couple of months there's was suddenly no backlight. I could see that the TF300T was working if I used a flashlight on the screen. So I got a cheap LCD screen HSD101PWW1-A00 Rev:4 from China and replaced the screen (replacing the LCD is quite easy). However now I had problems with permanent ghost touches so the tablet appeared unresponsive. Firmware had been updated to 4.2 in the meantime so no root, however the bootloader was still unlocked, so I put the TWRP recovery for 4.2 on the tablet and installed superSU. Then I reinstalled the firmware for the digitizer PCB and the ghost touches are now completely gone. I have been using it for a while now and the tablet looks (and acts) like it's brand new. :D

[Transformer TF300T Q&A, Help & Troubleshooting] Krinkle01:
Further to my entry from a few days ago:

I managed to root the TF300TG using Kingo. Quite simple to use, the app does it all for you.

After that I opened the tablet and found a G01 digi: makes life so much easier, right!

Removal from the frame wasquite involved and cost me a few cuts (the glass is really, really sharp!) but it came out.

Used a special cleaning fluid to remove all traces of glue/tape, but forgot to measure the thickness of the glue.

also, this thread never mentions that the LCD-frame is stuck on separately from the plastic digi-frame: no biggie, but still...

One question remains for now for me:

Having seen the pointers to 3M-tapes, it strikes me that these tapes are very thin. The stuff I removed from the frame looked like a foam-type tape that was a little bit thicker, like up to 1 mm. The 300LSE-tapes mentioned earlier in this thread is 'only' 0,1 mm thick....

It strikes me that using a thinner tape might result in 'interference' between digi and LCD (like hovering a finger just above the screen).

What do the 'experts' think?
