[Q] Screen Replacement Leads to Unbootable Phone - One (M7) Q&A, Help & Troubleshooting

So I recently cracked the screen on my HTC One m7. I bought a replacement screen and front housing. The screen was so far beyond repair that I couldn't shut off the phone prior to starting the replacement. I tried waiting for the phone to die but after two days I became impatient and did it anyway (essentially the phone lost power when I disconnected the battery). After transferring all parts into the new housing and being what I though as diligent putting all parts and connections back in their place, tried to power the phone back on. all that happens is that the back and home buttons flash and then I hear what sounds like the audio for when the phone powers on. The screen stays black and then phone doesn't technically turn on. I know this because I have missed messages and the green led light would be flashing if it was. Therefore, at this point I'm not certain that the new screen works or if I've connected it right. I've tried the numerous boot tricks with the volume buttons, nadda. I have had the phone on a charger for a full day and the same problems. (Disclaimer: I don't have the original charger, but I have been using this one for a long time). I do see the red charging led if I wiggle the charger in the input, but also just recently I saw a green led when doing this, which when the phone was working was a sign that it was fully charged. If anyone has a solution to my problem that would be great. I'm also interested on what's wrong, why this is happening, what might have caused this behavior? What do the flashing home and back buttons mean?

Howdy,
I've had the same problem, but my phone was shutdown allready. When I replaced the front screen, the phone won't boot. I would like to know if its anyway to get the files from sdcard down?
Thanks for the support!

WTF: LED light constantly on/won't turn off

My camera led light just started acting funny an hour ago. It turned on and it si now impossible to turn the damn thing off. It still stays on when the phone is turned off. I've tried removing the battery and then put it back again. As soon as the battery is in, the light turns on again. I've tried a soft reset and ultimately a hard reset. Light remains on.
Don't want to have to go to Sony for this because I bought the phone off the bay a month ago and therefore don't have a receipt so it won't fall under warranty. Anyone have any ideas? What a pisser.
hi,same here
I think its a hardware issue where the cables have been short and are giving direct connection. I dont know if this will work but try to tap the phone a little hard on your palm. If its just a loose contact it might get sorted. This is a very crude way.
You guys want help or just venting air?
Great story.... so ?!
If you guys want venting off air, that was it! If you are looking for help however, then KINDLY state some info, like:
what the frak is the phone model, firmware, recently flashed, if so to what. Branded or unbranded, built date, etc.!
After that, perhaps a few answers can be expected
MichaeltheImage: I doubt that in this case this had anything to do with software because of the fact that it remained on after a boot or when the phone is off.
Moleculez: Yesterday it ended up fading by itself after 2 or 3 hours. This morning it started again as I removed the battery. Tapped the led side of the phone on my palm a few times; and it worked. Thanks.
"Anything mechanical, give it a good bash."
Incase someone is still looking for a way to fix this problem:
I managed to pry the plastic covering off of the camera lense/ LED with a needle.
All it took was a slight nudge on the LED cluster to reposition it. It was situated slightly off to one side, causing the short circuit which lead to the LED being constantly lit.
Problem is, in my initial frustration I poked the LED and broke it which, as a result of the short, meant that although the LED was no longer lit it still drew power from the battery.
The only way I know that the later fix worked was by using a power consumption monitoring tool to verify that the LED (and the short circuit) was no longer drawing power.
Awesome.

Time for a new phone?

So in the middle of the day, I pulled my phone out of my pocket to check the time. I was faced with a black, backlit screen. It'd turn off and back on every 5 seconds or so. I pulled the battery, attempted to turn it on, but I was faced with the same black, backlit screen. It continued the cycle.
I tried powering it on in bootloader mode. This caused the backlight to stay on continuously, but again, nothing on the screen. No M logo, not even a faint hint of text.
Is this phone done for?
It may be possible that it is just the screen, however I do not have the phone to look at it. If you plug it in when it is powered on do you get a recognized device on windows/linux?
The wires connecting the LCD screen could also be loose. If you are at all tech savy you might try taking it apart and looking at it.
The Droid is an amazing phone, but it is getting outdated pretty fast. I still use the Moto Droid and have no problems.
Do you have the insurance with Asurion? if so you can send it in and they charge like $50 to replace the phone.

I would contact the manufacturer/carrier if there is still a warranty. If not, I would still contact to see if there is anything they can recommend, or if they will fix it for a minimal fee. Otherwise, look up how to take apart your milestone/droid on these forums and check for a loose connection or something. If all else fails, you may be able to buy a replacement screen. Those are the steps I would follow, but contact motorola/carrier first no matter what.
Good luck.

[Q] Galaxy S I9000 Problem turning on...

Here's what is going on...
My Galaxy S I9000 (Bell Canada) was water damaged, after being dried for many days it turned on, but the battery almost immediately drained. I left the phone and forgot about it. Bought a new cheap phone without a SIM.
More recently I got a new battery for it and it turned on and was working great, staying charged and everything. When I went to the service provider to get a new SIM for it, we powered down the phone, pulled the battery and SIM card and put the new SIM in followed by the battery. Afterwards the phone would not power on, but the two face buttons on either side of the 'Home' button lit up and would react to touch. I tried removing the battery and SIM a few times and would get the same result.
After bringing my phone home and leaving it with the battery out for a few days, I thought I would try it again. It powered up again as if nothing was wrong. To test it again, I pulled the battery and SIM, replaced them, and my black screen/won't turn on problem returned.
Every so often it will power on and be useable. It is recognized by Kies, I've flashed it to firmware 2.3.4.
I'm looking for any helpful suggestions for what might solve my problem. I'm wondering if it's a hardware problem and short of isolating the part of the phone that is faulty and replacing it, the phone is toast.
Thanks for your time, and I apologize for the length of my post.
My friend has dropped the SGS into a pool before. Problem was fix after buying a new battery.
Either: Damaged screen + Contact. Or the reaction with water and the battery. hydrogen gas prevents screen from connecting to main-board.
It still turns on occasionally, and when it powers up, it's as if nothing is wrong. Screen works, displays everything fine, colour is crisp, screen reacts to touch. The big problem is it won't turn on all the time. Would what you said still explain this?

The only thing I know (assuming the screen or motherboard is 100% functioning) is hydrogen gas being present. You might know TV remote with old battery casually respond to presses. After cleaning contacts it should work again.
I disassembled the phone and cleaned all the contacts on the main board with rubbing alcohol, I did not do anything to the screen though. Should I try taking it apart again and breaking it down further? (ie. separate the screen?)

No, I am starting to think it's a hardware fault if that didn't work

[Q] HTC One Is Completely Dead [Closed]

This is the first time I have ever posted to the fourm so please don't tear me apart.
Anyways I have a HTC one that I bought refurbished back in September and it has been great until tonight. I had it plugged in charging, watching a YouTube video when static went through my headphones and the screen got really fuzzy and then the phone shut down, but left the notification light on and the capacitive illuminated. I held down some combination of buttons and managed to get it turned off. It will now not show any signs of life, the notification light dosen't turn on when I plug it in to the charger. I have tried different chargers and holding down every combination of buttons I can think of and it still wont boot.
Any help would be really appreciated!
EDIT:
This morning I casually took my phone out of my pocket and pushed the power button and it just started up like normal. I have no idea what changed but it works now.

My phone was in the same situation, try lots of method.
I just installed Ubantu and do what dexter93 advised in the above topic.
It's charging now.

black screen after replacing.

I was replacing LCD in my Xperia. Tested the new screen with phone opened, everything was fine. Started assembly, one last test to make sure everything is working and the phone won't torn on. So I plug it in. Everything as usual. Red led. After some time I try to turn in on and it just won't. When I hold power button there is this short vibration like it is turning on just fine, but screen is black and I can keep turning it on ( single vibration over and over).
I tried both resets.
LED light is now green. So battery should be full.
Any idea what I could done wrong?
Old screen wont work either. It worked before.
The screen is broken. when i plug the phone to the computer it makes a sound. Any idea how to reapair this? i did not damage the screen.
