Screen Will not turn on. - One (M7) Q&A, Help & Troubleshooting

EDIT: FIXED
i know this has been posted many times and i have yet to find a solution that has worked for me
I put my phone to charge before going to sleep and everything was fine, but when i woke up and tried to check the time my screen would not turn on
i noticed the light was a static green with blinking orange and even when the charger was disconnected the green was still there and still blinking orange
ive held the power and volume buttons and tried charging it more but nothing the notification light is still green and orange the soft keys are black
i also tried hooking the phone up to my pc and preform adb commands to get it to reboot :crying:
im on the VZW HTC One rooted with custom rom
Any help or diagnosis would be appreciated

try...
I would try cooling the phone down by placing it in an air tight bag then leaving it in the freezer switched off for about 15 mins
Then try switching it on.....
With my phone i had the same issue.... when i opened up the phone to look at the problem. I realised that there was some moisture corrosion on the LCD Screen cable.... easy fix - just clean cable ends with circuit board cleaner.
Try it and see what happens.

Tytn II possibly dead HELP!!!

It looks like my Tytn II might be bricked... I have searched and searched and can not find any info on this. The phone will not turn on. I know the battery is dead, but it should have the power to try to boot. In fact, I have not used it in a while and I just tryed to boot it, it got to the starting screen, then the windows loading screen, and then I walked away for a few minutes and came back it and it was a black screen. Tried to turn on again and it did not power up. Upon plugging it into the charger, I get a solid red light on the top. When I remove the battery from the phone as the charger is connected the LED immediately changes to solid orange, and the blue led next to it comes on as well. When I disconnect the charger all the LEDs go off (obviously because theres no battery) and when i put the battery back in the phone i get a dim red light.
is the phone bricked? im thinking it might have slight water damage but it has been like 2 weeks since then so it should have dryed up i assume. tried to reset a few times with the little reset button next to the charger port, nothing. is it possible the battery may just be done for? any help or suggestions would be great. thanks.
I had that isue but i just leaved the phone on charger and everything came back to normal It's still working very well. But, i cant remember how i get into that situation but i surely know that i saw red light on top .
thanks, now that its been on the charger for a while i now get an orange LED. i will let it charge for a while and see if it awakens after almost 3 weeks of utter deadness.
Try waking it while on charge itslef.
Regards.

just tried and it got to the very first boot screen and then went black and the orange and blue LEDs stayed on. tried to reset, no luck. unplugged charger, still LEDs stayed on. so then I took the battery out, all LEDs went out, plugged it back in and now i get the same red LED again.
update: now i get a orange LED as its plugged into the charger, but when i try to turn it on it gives the first boot screen for like 3 or 4 seconds then turns off...
I am getting exactly the same problem?
I tried to install android - got it working, came on a few times - then just totally died - It showt he HTC boot logo, but then just turns off.
Does anyone have any ideas.
does your computer see it when plugged in via usb?
perhaps this will help? http://forum.xda-developers.com/showthread.php?t=358136
oh and also you have tried to enter the bootloader mode right?
I've had this issue, millions of times. What I do when I have problems like this (and problems like when I turn it on, it says the battery is low when it isnt, and when you connect your charger/USB, it dies on you)
Try removing and putting the battery back on.
so in simple words
charge the battery first (dont bother trying to turn it on)
and then remove the charger (this plays a big role)
take out the battery, put it back in, hope it works.
The same thing just happened to me, I thought it was toast. I would get the red light when I plugged into the charger, and after a few minutes it would turn to orange. I tried to turn it on then, and it would start to boot up, then shut off a few seconds later. This happened a few times. I just left it plugged in overnight, and when I woke up it was on! Only problem I've noticed is the orange LED is always on, but I can live with that

Xperia Z without LCD

Hello, I cracked digitizer of my Xperia.
So I took it apart and wanted to fix it.
I heated, took LCD and digitizer off, tried to separate them nicely, but I'm pretty sure I made a little bit of damage to LCD.
Anyway, now I wanted to try phone without screen before ordering parts (you know, maybe I damaged motherboard or something... )
So... I plug all the cables, make everything back except digitizer is off now, but LCD is on.
I try to turn it on, it vibrates and that's it. Nothing more and after waiting over 10 minutes it still doesn't show any signs of life. Plugging USB cable from PC or ac does not show any signs. I can't do anything until I unplug battery and plug it back.
If I try to stick USB cable before turning it on, red led flashes brightly and that's it. What's even more interesting, if I unplug the cable, led keeps flashing and I have to unplug battery again.
I can see green led flash for a second when holding volume up and plugging to PC and blue led keeps for long time if I plug to PC while holding volume down.
So now you know my situation, does it have to be like that or no?
Maybe there's a back signal from LCD I mean if it's not connected, phone does not work or something.
Before everything phone was working perfectly.
Hope to hear some advice, thank you.

Its looks like a mo-bo issue for USB and LED issue. Check whether all connectors are in place.Also for digitizer issue i thing either the connector is not properly attached or the flex cable is damage.
Any more opinions?

[HELP] Xperia Z brick?

hi,
sorry for my bad English,
I bought Xperia With a damaged touch. The phone is normally turn on. the touch did not work. I decided to take himself for the replacement of touch (glued to the LCD). I disassembly phone . before removing the motherboard still plugged in the battery to see if the battery will not hurt the dismantling of the display, the phone is turned saw the Sony logo and disconnected the battery (do not know if it was a good idea). After removing all nicely warmed the screen and slowly removing pieces touch. Unfortunately, at the end it turned out that a little too much it warmed, because the screen began to appear discolored, so were pissed, I ordered a new display and in the meantime, as I wait for the touch I wanted to see if it works. I have connected to the display board, tape, buttons and battery. Turned on, the phone vibrated and enough black screen. So I stitched it to "poop" and I wanted to run, but it was all the same. Computer can not detect, etc.. After some time, as it was plugged into usb turn on the red light. Ive loaded software program SUS, and after you press the power button flashing red LED 3 times. I left the phone on the charger overnight from nokia (1200mA), but it does not improve, after that, that when you try to turn the vibration and again, so much. The phone is detected in fastboot mode (blue LED) and flash (theoretically green), because as I press the phone turned off and hold down my Vol- is a second red LED will flash immediately changes to green and then turns off the computer recognizes the phone as SOMC Flash Device (SEMC not SOMC) and in this mode for the update service is normally upload the software to the end, in the Flashtool the same situation. I do not know if it's important, but after every uploading the software when you try to turn this unfortunate flashes red LED 3 times as if the battery is discharged. Could this be a defective battery? Phone before you got in my hands was lying unused for some time. How it got it it plugged into the car charger (840mA) for around 40min +/- and normally work. I do not remember whether if it was on some LED.
Why could you buy a Xperia Z with damaged touch? And why you try to repair it yourself?
Tapatalk'ed from my Xperia™ Z (C6602) running Dirty Unicorns ROM!

If battery was working properly before the experiment that you did there must be something wrong that you must have did.
Try a different battery and see whether it solves issue or else you must have damage the mo-bo

Stuck in flash mode.
Fastboot and flash mode works. (Blue and green led)

Note 3 failed to charge while the phone is off

The power button broke on my Note 3, i reassemble the phone hopping to fix the problem, i found out the small dome shape piece of metal is out of its place and there is no way to put it back, also there is a tiny piece of clear reddish plastic to cover that metal dome, i found the whole circuit in amazon and i ordered one.
i closed the phone back after connecting all connectors back, i did that very carefully.
when i connect the charger (the phone is off) a gray battery icon shows for a couple of seconds then the phone screen become bright white for few seconds then turned off, the charging LED indicator is off. usually the battery icon changes to green with 5 green dots underneath it indicating the phone is charging.
if i disconnect the charging cable and put it back nothing happened, if i disconnect and connect the battery then plug the charger, the gray icon an white screen scenario above happened again.
I remove the battery overnight and tried it this morning, i got the same behavior again.
any help is really appreciated.
Phone: unlock ATT note 3 with custom ROM.
WOW, am I the only lucky one with this problem???
I found out that the battery is really charging, but neither led nor the screen are indicating anything, I figured it out when i noticed the battery is worm,
Also i was able to manage to boot my device by connecting the charger while pressing the Volume down and home button, i was able to go to download mode then restart the phone using volume up.
the phone is charging fine when it is on.
Not sure about the main issue if it caused by the Power button or something else.
Update:
I have a bad ROM causing too many problem, I flashed to NC2 4.4.2 and every thing is working, no wonder why nobody has this issue.
Thanks,

Blinking Sensorbuttons after disassembly

Hy, a friend of mine brought me his Htc one m7 to fix various things.
I changed:
Display
Middleframe
backcover
daughterboard
earpiece
speaker
Atfer i was finished i tryed to power the phone on but only got blinking sensorbuttons.
I checked all the connections between the boards in the phone.
I checked the Proxymity sensor - it is connected and was working before.
I tryed to start it with Power + Voldown
the battery level was at about 50%
i tryed the trick with shining light on the prox sensor
After trying to power it on the mainboard got slightly warm (it was barely noticeable without the Backcover) and stayed warm until i unplugged the Battery. after that i have not tryed to power it on and it didnt get warm until i tryed to power it on again.
Anything else i can check?
Edit: phone was charging over night. No charge led and no powering on
EDIT2:
Found the fault - the new display is broken. it does boot but shows no picture. Because the phone is silent it didnt vibrate or make a sopund on boot.
