Broken Display?

ok so here is the rundown
Device: HTC one on vzw
Rom: Slimbean 2.x
Gapps: Slim AIO gapps
had a weird problem with the display today if anyone has had this or know someone who has i would greatly appreciate the help. I just flashed Slimbean 2.x last night and all was good. no problems what so ever, got everything setup and was working fine. this morning around 10am i opened snapchat to view a video. i clicked on the video and as soon as it started the screen went blank and would not turn on. i tried holding the power button down for at least a minute and nothing. also tried power and volume down, power and both volume buttons, power and volume up and still nothing seems to work. when i plug it into the wall charger the red LED light does not turn on and screen does not wake. when i plug it into the computer the computer does not ever read the device and noting pops up letting me browse the files on the phone. i have no clue why this happened it has been working fine for the 3 months that i've had it. took it to verizon about an hour ago and they didn't know either but they are sending me a replacement htc one. all i really want now are my photos that i have on the phone.
does anyone have any ideas about what i could do?
thanks

I had something similar and think it was conflict related. After installing the "advanced power menu" with xposed, I had an issue when trying to use it to boot into recovery. Basically it had timed out and then went away without rebooting. The next time I tried it locked up and my screen went black. My keys would light up if I clicked on the power button (it was dark in the room so the sensor was still working), but nothing else. Nothing I did would make the screen turn on at all and holding down the power key to reboot did not work. I just planned on letting the battery die out. After about 45 minutes, the phone just rebooted and everything was back to normal. I really think it locked up due to a conflict similar to what a PC might do.

Help: G3 doesn't power on - Only blue/green notification light blinks :(

The G3 just dropped down on the floor with the circle case. Then It was working some minutes apparently with no problem, until I myself turn the phone off and restart it. Then the device just didn't turn on. The only thing is that the screen is black and the led notification blinking green and blue
when i connect the charger, the red led blinks once and then disappears, then after 30 seconds the red led appears which apparently shows that the phone is charging the battery. Also When I connect the phone to the PC, a sound of connection is heard from PC but the PC doesn't complete the device recognition process as no new device is found.
I tried to make a hard reset, but nothing happens when I press the power and volume down keys. Tried some other tricks with the battery and the hard keys on the phone but no result at all, as the same story just repeats. Does anybody have a solution for the problem? This devise is the only android device I have

Help
Please Help :crying:

Did you do anything else after/during the time that the phone was off? And is there no possibility that you cracked the LCD digitizer? I mean it might sound strange but this is what I had with my old phone. I dropped it, nothing serious but then I put it in my pocket and upon taking it out I noticed the screen not turning on. As stated above, my digitizer was broken and multiple people told me that the digitizer had a small crack which I didn't notice, then when I put it in my pocket I put too much pressure on the digitizer cracking it. The LED-light did work though, and this sounds very similar so my advise going to the store and asking wether they know what the problem might be.
(Hopefully this was helpfull hehe)

If you Don't see the LG splash screen when pressing the power button it seems like a screen or digitizer problem for sure.
BUT;
after you try turning it "on" let it sit a few minutes and see if you can call your self or send a text to see if it makes noise vibrates etc. to confirm a screen problem.
OR
Also you can try putting it into download mode.
Battery pull (don't turn on)
plug USB into phone but not computer
Hold volume down AND then plug usb into computer
if this comes up to a pic of something on the phone it will be software related. to get out of this mode you can do a battery pull.
Remember to always read up on topics and things you are doing. There are guides here on XDA to help you out.
Hope you get your phone working

I didn't do anything special after/during the time the phone was off. I checked the screen very carefully under a lamp. No particular sign of crack. Thank you very much for sharing ur experience.:good:

I tried to put it into download mode, but no result at all as no connection could also be made between the phone and PC. Moreover, I tried to make a text/call, but nothing is received by the phone. Thank you very much for ur suggestions.

Seems like the drop damaged the memory and the phone can't reload it, you will have to bring it in

Yeah that's plausible ! I'd bring it in too
Hope you fix your phone fast

Yeah... Probably it's a hardware problem. Someone who checked the phone in order to fix it, said that the problem had been with the device board. Even though I was satisfied with the phone, I have found out that the G3 is a sensitive device, as the height of the table from which it dropped down wasn't too much. So always take care of your G3 phone.

[Q] Display and touch screen major issues following lollipop update.

Problems with my Samsung Galaxy Tab S 8.4 SM-T705:
1st: October 2014
2 weeks after buying, my tablet's battery drained overnight from 45% to zero. Next morning, I turned my tab on after charging to find out that the Tab starts but without any Samsung GAlaxy Tab S logo or Samsung Logo and the Screen has turned green, rendering it difficult to read in auto brightness mode or low brightness mode.
I restarted the device 2-3times and the device started working normally. This was my 1st device restart. I never used to power off the device before.
In 1st 6months, this greenish display problem n logo problem occured 2-3times, and i ignored it, because, it used to get resolved by itself with restart and I had no service centre in and around 50km to my work place.
2nd: January 2014
My device all of a sudden stopped working.. actually hanged.. I managed to turn it off but failed to restart it.
Later I realised that the device has restarted, but the screen was not responding when the screen blinked for a moment with the opening of book cover.. and the back cover of device was warm..
Googling taught me the way to access recovery screen n I opened recovery mode with "power+vol down+home key" and pressing vol down in recovery screen to restart tab.. again the tab started working fine..
3rd: Lollipop update: May 2015
I did Lollipop update. The device was smooth to operate at first. But gradually, i noticed that unlocking the tab failed to light up the display everytime, just the soft keys lighted up. But one day, the device freezed with no response from touch screen. I was unable to switch off the device also.. I had to drain the battery by playing music using S voice to turn the device off. "power+vol down+home key" too was not working.
On googling, I learned to reset device with "power+vol up+vol down" keys pressed together. finally the device restarted, but the device used to hang occassionally.
Googling let me know that i need to factory reset device upon firmware update for normal functioning, which i didn't do after update. so, I backed up my device, uninstalled many apps to make the device run a bit smooth and did a factory reset.. Resetting didn't improve the situation much, but now, the device display failed to light up on a regular basis on unlocking most of the time..
Now the situation is that, the device turns on, finger print scanner works, all apps n everything working, but display remains black, and touch screen is not responding.. using sidesync, everything on Tab can be accessed via laptop.
Tricks tried:
1) Factory reset
2) power+ vol up+vol down
3) power+ vol up+home key
4) power+ vol down + home key
5) Power off using sidesync and then restart
Results: All failure. Everything works but the display never lights up normally..
Plzz help....:crying::crying:

Bump. I'm starting to have similar problems with my SM-T800 running 5.0.2. I open the cover and the device fails to turn on. I press the power button and the screen stays black but the notification bar turns on. I can shake the crap out of the device and the screen stays black but I can see the notification bar flicker. Driving me batty.

If i had any problems like you guys, I would just return it to the place i bought it, for a refund or replacement or even a repair, post it to the service centre if it`s too far to travel too.
You problems sound like battery and or loose connector inside your tablet, it happens frequently on Samsung tablet for the connectors to come loose, if the tablet is dropped or twisted, no outside damage might be seen.

Screen stays black until the device is restarted

Hi guys, having some trouble with my tablet. Started out of nowhere, but the screen doesn't light up until the device has been fully restarted, in which case once you lock the screen, the problem starts all over again and I have to restart it again. It also lights up when the device is off and the power cord is plugged in, but only briefly. Once it goes away, I can't use the power button or anything else to check the status of charging, only thing that works is unplugging it and plugging back in. It's still sensitive to the touch, there's haptic feedback, capacitive buttons work, it just stays black most of the time. Has anybody else had this issue and knows how to fix it? It came out of nowhere, the device is not rooted, haven't dropped it or anything. Thanks in advance
