I've had my TF for about 4 months now and all of a sudden this morning I adjusted my brightness to a little over 50% and the screen went blank. Im running stock and not even rooted. The only way to get the display back on is to wipe and reboot. Even after wiping i tried turning up the brightness again and the same thing happened. Ive came to a conclusion that it only blacks out with the brightness turned up. I was wondering if you guys could help or it might be a hardware issue.
Thanks.
Probably a late reply but I had the exact same issue and I just RMAed my Transformer. They picked it up and returned it repaired.

My OWN ADJUSTMENT/PERMISSION, and I don't even HAVE ON Auto Adjust BACKLIGHT. I SHUT THAT GARBAGE OFF. I read on this phone PDFs so I need the screen brightness on.
So it's been happening for like 3 days now, since I got the phone 4-5 days ago.
Anyone else having this problem?
This is getting stupid, I hard resetted it and and soft resetted it and I'm on my 3rd ROM now. WTF? WTF? WTF? WTF? Man, this problem needs to get socked.
i still have the same issue after flashing with a new rom, soft resetting it and hard resetting it too, can anyone please help?
thank you so much.
Anyway I haven't been using the fuze for like a year now so if you guys can't fix it then no problem. So, the display does not show at all. When I turn it on you feel the vibration, however the screen does not light up at all, you get no display. How it happened was that I had slept on it by accident (which makes me think it be fix unless I do something physically like take it apart), when I woke up a realized that I was laying on it I immediately got up and the display was not showing.
I've tried leaving it plugged in for 8 hours and it didn't work......that's all I tried.
Thanks for all the answers.
I sleep on mine all the time...
Have you attempted to get into bootloader; to see the multi-color screen?
no display
i think its about time you opened the device up and seen whats going on inside
if you break it, no biggie = can't fix it then no problem
So, I've rooted my TF and been running the latest Revolver ROM for about a week. Everything ran awesome with very few flaws. I also recently RMA'd my dock for the sleep issue and just got it back yesterday.
I hooked up the dock to my TF and it ran great all last night and this morning. Everything charged just fine. I packed it up to take to work, took it out at work and...nothing.
My TF would not wake from sleep. I thought maybe I had suddenly encountered the sleep of death issue that I had heard about but never experienced, so I held in the power button and restarted.
The TF restarted just fine. Booted past the first screen and the custom animation screen. But as soon as it was supposed to boot into the homescreen, it goes blank. The TF is on as I can hear email notifications and stuff, but there is nothing on the screen. I tried booting and re-booting with the same result.
So I wiped cache. Same result.
After getting an MD5 Checksum error from the one backup I had of my system through CWM, I wiped data/factory reset. I actually got past the boot animation and started setting up my TF again. However, the screen was set to auto-bright (I like it at fairly bright) so I started to adjust it. As soon as I touched the brightness controls, the screen went black. TF still on, just no screen.
I booted back into recovery again, wiped data/factory reset again and again it booted up just fine and took me to setup. Went to adjust brightness in the actual settings menu and as soon as my finger touched the brightness bar, the entire screen went black.
WTF? Has anyone else gotten similar experience with your TF, either rooted with a new ROM or not? Not a whole lot I can do with a tablet with no screen.
Here are the things it is not based on my observations:
1. It is not a dead screen. On boot up, the screen works. Animation plays well. I can access the CWM recovery menu.
2. It's not a dead touch screen. I can factory reset and go into the setup using the touchscreen.
Here are the things I suspect it COULD be:
1. Something up with the Revolver ROM. I had refrained from applying the 2.1.1 update as the update immediately after that just reverts it back to the version before the 2.1.1. update. However, I did apply the update after the second time of factory resetting.
2. Something up with my dock/dock software? I didn't have any of this issue before I received my dock back.
Please, can anyone help me out here? Sorry for the long post, but wanted to include as many details as possible.
Does the issue occur not docked? Can you use the dock brightness buttons to bring back the screen?
It happens both docked and undocked . Dock brightness buttons do nothing.
I left the tablet alone for about twenty minutes and when I came back the screen was on. Brightness was at max. But again as soon as I touched the brightness controls no screen.

Actually (after wiping and restarting yet again) I found that even the dock brightness buttons cause the screen ti go blank.

Okay so after searching high and low for others with this issue i found two unresolved threads. It seems to be a software problem that will not allow the backlight to go beyond 50% brightness when not plugged into the charger. I'm at work now so I can't test this for sure until I go home later this evening. If this is the case, then it could be a problem with my root and ROM installation. I will try the following things in order.
1. Restore from backup done right after I gained root access. This is basically my system with the original software. After gaining root, I did delete some things through Titanium Backup that I felt were bloatware. This might have had something to do with it so restoring the original backup should return these things to their normal state. The only problem with this is that when I tried to restore from recovery, the MD5 checksum gave me an error. I have found a thread that allows you to override using ADB and will try once I get home.
2. Unroot completely and flash back to stock. It worked when I was unrooted and stock, so theoretically it should work again.
3. If the above two methods don't work, I'll just RMA it back to ASUS. I already called in and got an RMA number for the issue. At least by doing the above two things I can ready the tablet to be within warrany specs in case it's just a dud and needs to be replaced.
Will update with results.
Results
1. When plugged into the charger (with or without the dock) I can up my tablet to full brightness just as the other couple of threads I read stated. Even with brightness up at full and running on battery (blank screen) there is still HDMI out. Wish I had realized this BEFORE I did a complete data wipe.
2. Had to use terminal emulator and the following link to recover the CWM backup with the checksum error: http://forums.androidcentral.com/epic-4g-rooting-roms-hacks/70519-md5-sum-mismatch.html
It worked awesomely to bring my precious tablet back to stock with all applications I ran previously. Still no change in the brightness issue though
Now on to try to unroot and see what I get...
sounds like you're taking the right steps.
I hope so Malandro2011.
Looks like I will have to RMA after all. I unrooted, went back to stock recovery and a completely new install of the most current firmware. No dice. The issue is still there.
My tablet's all packed up and ready to ship off to the god awful Texas facility for repair/replacement. Since they sent my dock back with a bend in the metal near the adapter port, I made sure to take pictures of the entire tablet before replacement as well as leaving a note to them under the RMA slip about the condition of the tablet when I shipped.
My biggest question is what triggered this to happen. Was it rooting and installing a new ROM? So many people have done this without incident it is hard to believe this was the problem. Was it whatever changes they made to my dock? I was running smoothly for a week before charging it in the dock overnight.
many people have rooted and your the first I've heard with this particular issue so i doubt these roms caused it...but could be wrong.
Seems power related since adjusting the brightness sends more power to the screen or less then the screen fails.
I reckon its just faulty...
I wonder if they'll replace it with the newer models that cant be rooted yet..
Yeah, I agree it seems power related. My unsubstantiated theory is that when they adjusted the I/O board in the dock, perhaps it changed some of the power settings and caused some sort of overload/short in my tablet when I used the dock.
Such a shame to send it back. It was one of the earliest models and beyond this was one with the fewest problems. No light bleed, no stuck pixels, no sleep of death, good QC on the hardware. Here's hoping that what I receive back will be just as good (and hopefully not one of the unrootable new models).
Update for anyone following this thread. Received my repaired TF two days ago. Total away time was around 2weeks. It looks like hey had to replace the entire screen. Looks nice with even less lightbleed than before but the screen has a faint yellow tint that I have heard is common with later model TFs. Not sure if I should send back again as I really don't want it gone for any longer time...
Hi,
Got my TF700T one week ago, and the back light seems to be stuck in full IPS+ mode. I can change the settings related, the slider, etc, but the back light is just on, with a intensity like a little sun.
Battery goes away in about 3-4 hours when it runs like that. Have tried factory default, and anything else I could think off, including installing the new update.
Any suggestions? Fixable, or a DOA unit?
Thanks,

If you've restarted and factory reset..there isn't much else you can do but return it. Sorry man.
Hello everyone,
I am an owner of an LG Nexus 4 for a few months now.
The device worked well for the first few months, than one day I dropped it and the screen shattered
The touch sensors stopped working, although the LCD display didn't,
So I had the screen replaced and everything went back to normal.
Then, after the 4.3 update I think, I started having problems with the mobile connections, it died all of a sudden and didn't came back, and the device went off, and when I turned it back on, the battery indicator showed a lower percentage than before, than the device went off again.
Mostly, after the first shutdown the device wouldnt come back unless i charged it.
I also had the battery changed because it turnes out it got inflated (turnes out that happens), and it didn't help either.
I thought the 4.4 update will help, but it didn't.
What could the problem be? Is it hardware or software?
As the title says, I'm very frustrated. It could be from the hit he got when the glass broke, some interior parts could have got hurt,
Or from when the battery inflated.
or that I just got a crappy device in the first place, who knows.
Thank you and sorry for the long post.
Yours,
Yarin.
