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...
My screen recently broke and I got a new one. I installed it and when I turned on the phone the colors appear washed and I have to keep the phone on High brightness because on auto or low/med the phone flickers when I pan or when the screen changes from Black to White like when I go into email from the home screen. Any ideas? Is it a damaged screen or is there any settings I can try to correct this problem? Any ideas or solutions will be appreciated. Thanks
Send the phone back? My HD7 volume up button got stuck and I got a replacement. It crashed on me like 50 times in one hour and it was on the way back to T-Mobile within 2 hours.
Don't try to fix issues in replacement phones. You send them back and keep sending them back until you get a replacement that just works correctly.
TL;DR: Send the phone back ASAP and get another one. It's not worth the trouble...
Any chance of posting any pics of the problem?
Hi,
A few days ago my 1 month old (got the phone and service back on June 8 so just a small bit over 1 month old) Samsung Galaxy Q stopped working. I had to turn it off and then decided to turn it back on and the 1st screen I saw was the normal screen (Black background, white text) that said Samsung Galaxy-Q SGH-T589. The next screen was the regular animated thing that shows stuff from my provider (Fido - Canada) after that it would normally go to the home screen, but in this case it went to a black screen that had Samsung written at the top and would glow white and blue. It never got off that screen no matter how long I waited.
So I first tried to pull the battery out and put it back in and restart the phone.. Same issue. I then tried to do a hard reset. Same issue. (It didn't clear the cache during the rest. got an "unknown error")
Does anyone know what the problem can be or how to fix this?
And yes, I am planning to take it in to get sent back to get myself a new one assuming I can't actually fix this.
Thanx
Al
hmm.. maybe I should have put this in one of the Android forum.
since a few days,on my screen kept coming a light ,gray flickering on the down half of the screen that lasted just a few seconds,and then disappeared.
then,yesterday even the upper side of the screen got affected.
Since I noticed some improvements through unlocking and locking the screen,I thought it was a software problem (I have trickdroid 6.0 installed,so I reflashed the rom)
after full wipe and rom reflashing,the problem was still there,it keeps coming out after a couple of hours,but it was still present.
today I did a factory reset from the bootloader(deleting everything)and reflashed the rom.still there.
anyone got the solution???would help a lot,thanks!!!!:fingers-crossed::fingers-crossed::fingers-crossed:

Well, the only thing that comes into my mind is to full wipe, download a different rom, flash it's own kernel and try it...
If it's still there, I am afraid it's a hardware problem.
since the problem keept being there,I sent it to htc...the motherboard was faulty so they replaced it
I bought a Samsung Galaxy s6 last month. After a week of use I noticed few problems. Firstly, my phone used to turn off by itself (it was on the stock rom ) the problems appeared when I update to the latest android version ( 5.1.1 ). After one week every problem has disappeared and it was perfect.
But now, one month after buying it, new problems came. Color lines appears sometimes on the screen ( not everytime ) and then all the screen has changing colors and showing lines everywhere. To resolve that, i've just to turn off the screen and turn it on and everything goes alright but... after minutes, the phone turns off by itself and its very complicated to make it turns on. When I finally turns it on, I see again these lines and I can't turn on wifi and the camera.
It has never felt in the ground or in the water, so I don't think it's an hardware issue.. So I tried to flash a custom rom on it " XtreStolite-2.0 Odex.. " And the problems are still here.. I don't know what to do since I used all my small knowledge..
Hope someone will help me.
Thank you everyone.
