Sporadic Touch Screen Failures? - Transformer TF300T Q&A, Help & Troubleshooting

So I got a refurb tf300 from Woot the other day and it looked and worked like brand new until the touch screen stopped working completely. Left it be for a couple hours and came back to find it working. This happens a couple times a day, it stops and then it starts working. I can occasionally get it to start working again if I flip the device around any which way but there is most certainly an issue with the hardware. I have a feeling it might be some sort of loose touch screen issue.
To make matters worse, I unlocked the bootloader and rooted it to run CleanRom (great ROM BTW!)
I've heard Asus's RMA service is a nightmare (especially with it unlocked) so I wanted to check in and see if anyone has heard of this or has any ideas of how to fix it. Since it's clearly hardware related I can probably have them fix it but don't want to be out a tablet for six weeks.
Have already tried a handful of cold boots per recommendations online.
Cheers

[Q] HTC HD2 Screen Not Working

I don't know if this was ever fixed but I just bought the HD2 off a friend and i saw it work for him but when i received it, it boots up normally, but then when i try to touch the screen, nothing responds except for the actual buttons. It seems to be running fine, just the screen doesnt respond to anything. No warranty. Is there a fix?
It sounds like the digitizer may be busted... You could consider trying to replace it yourself but it's a tricky business, especially when some models of the Leo require soldering to get the new one on
You could also try a different ROM. To be honest though, I would ask for your money back, as it's not in the condition you wanted.
I am wondering if this truly is a digitizer issue. This happened to me the other day. I reflashed my nand rom, and it eventually "woke up" and started working fine after about an hour.
Very strange, indeed. I'm hoping it is a software issue and that my digitizer is not failing...
love to hear some more thoughts on this!
I also have this issue, but when I press the screen very hard (very very hard) or when I press the end call button continuously then it works all again.
Same thing here. I got my HD2 since last March. It works really well until recently. If I let it sleep, the screen would not respond at all when if I wake it up. Luckily, it still under warrantee so T-mobile will replace a new one for me.

Portion of the touch screen is unresponsive sometimes!?

Hey Chaps,
Wondering if anyone has experienced this one before - my transformer is about 2 weeks old and I've just noticed in the last few days a funny 'unresponsiveness' of about 1 inch of the touch screen from the right hand side (this covers the "App, + , and Time " portion of the screen. no matter how many times I tap it just doesn't respond.
Heres the strange part, I flip the tablet 180 and i can close execute "Apps, +, and the Time" features no problems! Switching back also allows this to occur.
I'm totally baffled. At first I thought it may have been some software issue so I've tried the following:
- restart
- factory reset (twice),
- cold reboot
Still no go, I've downloaded a multitouch app and testing shows the same thing!
Cheers in advance for any assistance provided.
p.s firmware is 8.6.5.9 TW
Sent an email to ASUS to see if they will recommend anything.

excuse the heavy breathing & poor camera skills - i'm sick.
experienced the same thing. i bought my tf to an asus repair center, said there was another one with the same case as mine, making me the second. they said they fixed the first one by upgrading roms. i highly doubt that though, since i tried everything from reflashing stock to rooting to a custom rom.. everytime, there's still a weird unresponsiveness that randomly appears and disappears..
neilbantoc,
I think I nailed it down - I turned it off, and left it off last night. When I started it up this morning, it was all good - I was amazed as I thought it was gone. Then it came back after 5-10 mins after some surfing / games. What struck me that I never really put 2 and 2 together is the back plate of the affected area, it was hot!
I personally think it's an over heating issue and not a software issue. The seller said it was their first TF101 returned and they have sold many - guess we just lucky we got lousy ones?
I got an exchange today and no issues so far! Fingers crossed.
Got the same problem, tried different roms, kernals.etc, will send it back for exchange.
I had a similar thing - Try downloading a drawing app and drawing lines SLOWLY down the screen with a stylus (fingers are too fat).
This may reveal areas of touch screen which don't work at all.
For mine I had a line nearly an inch high level with the speakers running horizontally across the tablet.
If you have this, get an exchange - their repair of mine failed and made it worse, and it took a month, so IMO don't risk a repair.
Guys, I can confirm that the problem has gone away with the replacement. It was definitely a hardware related issue (I still think it's over heating )

[Q] Why do we put up with it?

Not sure where my previous thread went, I didn't think it broke any rules?
So we have the latest WW update now and it still doesn't fix the SOD issue, do we not have any legal rights against ASUS? Why are we just accepting it? Yes, we have custom ROMs which attempt to fix the issues that ASUS can't, but even those aren't successful.
Every time I come to use my tablet it's either in a SOD or the battery is completely drained, when I was on HC I was able to get 5 days standby pretty easily and not once do I recall it rebooting or having any other issues.
ASUS turn a deaf ear when I try to get an answer from them on their Facebook page, either ignoring me or deleting my posts entirely, I suppose the next step would be to start an RMA request to see where that gets me but I honestly don't think it's something their the RMA centre can resolve as it's affecting so many Transformers.
I'm really frustrated with the whole thing, my Android phone works flawlessly, an SGS on 4.0.3, but my tablet is such a nightmare! It's really soured the experience, so much so that I don't think I would want another, add to that, I don't think I will buy another ASUS product due to the lack of support they've given me (I'm only 6 months into a 12 months warranty as well).
I too an saddened by my transformer's performance as of late. Mine is getting worse I think, Not sure if it's because of the flashing different ROMS or not. I've only really flashed two different ROMS. EOS and AOKP.
Now after a fresh flash my tab just freezes with the screen on, touch inputs do nothing, the screen is frozen. I will force it to shut off and it will not turn back on, or it does turn on in some way but nothing on the screen appears, I have to leave it for a day to drain the battery.
Since ICS I do not even use it, I can't. Really saddened, it could be a great device but it is now just slightly better than useless. End of rant.

[Q] Asus Fonepad 7 K00E won't boot at all!

Hi everyone!
First of all I would like to thank everyone who took the time to read this.
So about a year ago, I bought an Asus Fonepad 7 Model:K00E. Of course that decision was heavily regretted due to the uncountable bugs and malfunctions due to low manufacturing cost and non existent support from Asus itself. Anyways, so I lived with it.
A month or so after buying it, it fell screen first on concrete floor. And as you expected, the touch screen broke. ONLY the touch screen though. So then I had it replaced.
From then on the real problems began, touch screen would suddenly freeze when connected to charger, keypad would type on its own occasionally, and SD card reader no longer worked. Basically they screwed it up even more. Oh and when I changed the screen and made a factory reset due to thinking they were software related, it booted and said android is upgrading (like when you wipe dalvik) but if literally upgraded to KitKat.
Anyways, so problems stopped after a while and and came back occasionally. It worked okay for months, then one day when I was restarting it..it didn't boot..literally. Nothing even showed on the screen, it never turned on. It would just vibrate then nothing would happen. When I took it for fix and repair, since there literally no support from Asus themselves, I took it to a third party shop. After a few days I realized that people who worked there didn't know **** and just said it needs a new software.. Then they said the mother board needs to be replaced (which is basically like buying a new one..even the prices are close)
So I want to ask if there is anyway of fixing it or if anyone experienced this and how they solved it.. Sorry for the long post, just wanted to give every detail so you'd see the full picture. Thanks in advance, any and all replies are appreciated!
my device also switched off yesterday and now won't boot up, did you found any solution???
I some problem, this no boot is a only startup on recovery mode

The service centre guys confirmed that the device's motherboard is dead, so I bought a new motherboard and my tab is now working good

broken touch screen fixed itself

A couple weeks into using my new nexus 5, half the touch screen stopped working (if you really had to, you could still press buttons by pressing the thing really hard). It seemed like it was a hardware issue so I unrooted and wiped the device with this guide
http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
with the intent of returning it. Part of this process involved TWRP (where there are touch controls), and the problem occurred even there. (to me, that seemed to confirm it must be a hardware issue).
Now after everything is factory-reset, the touch screen has magically started working again. I'm extremely confused how this could have happened. My best guess is that the issue was intermittent and i accidentally jiggled the phone in a certain way to make it start working again.
Does anyone have an idea what could have happened, or how I could stress-test things to find out? If it is indeed an intermittent issue and the phone needs to be replaced I'd like to do that ASAP because I'm leaving the country and dealing with warranty will be difficult from overseas.
