G1 screen and power issue after touch screen replacement - G1 Q&A, Help & Troubleshooting

I disassembled my G1 today to replace the touch screen. The touch screen glass was broken, I took the device apart removed the damaged screen and installed the new one. When I got everything back together, I get very little response. I press and hold the power button after a few seconds the device vibrates momentarily then nothing. The LCD doesn't light up, the power LED doesn't light up when the device is plugged in. Any ideas?? I'm thinking that the LCD flex cable might have been damaged, but I'm unsure if that would effect the power/charging LED when plugged in.
Any help here would be most appreciated.
Thanks!

HTC Diamond Power Button Broken

hi,
yesterday I disassembled my phone to fix a microp error that had occured when i had dropped my phone. i disconnected two cables (one for the keyboard, the other for the lcd screen). then i reconnected them both and then went about reassembling the phone. however I accidently ruined the power button of the phone when i was doing so. a little part of the power button came off (a black button with the black sticky tape).
when i connect my phone to a charger and the enter button shows a pulsing light indicating it is charging.
so i was wondering does anyone know how to fix the power button for the htc diamond, does it require any minor soldering? or is it possible to turn my phone on any other way so that i can assign a different key to act as the power button.
cheers.
You can turn the phone on by using the soft reset hole on the bottom with the stylus.

[Q] Massive Problems

Hey all,
I just installed a new digitzer on my Vivid. Everything went fine, and nothing broke as I was taking apart the phone, or putting it back together.
Now that the phone is back together, however, it is having some problems.
First off, When I try to power the phone on, it vibrates like usual, but then doesn't display anything. The phone then proceeds to enter in to a bootloop and keeps vibrating every couple moments. When plugged in to the computer, the orange light comes on for a few seconds, then turns off. Windows will not recognize the phone. All the while, the screen is completely black, and none of the lights come on for the buttons either.
The phone was working fine before replacing broken digitizer.
The phone is NOT rooted, nor has it ever been. I am running stock ICS.
have tried entering Hboot with no avail.
Any advice?
Thank you!
Can you get into any other modes? Try to get to hboot(hold down power button and volume down) while plugged into computer. Should take it to fastboot.
how long for? I tried holding down for a good 30 seconds...nothing happened other than my orange light turning off
I noticed with mine I had to go with:
Remove battery.
Replace battery
hold vol down + power
few seconds later release power
few seconds later in hboot
YMMV due to repair.
You can also try a knoppix boot disc and some tutorial to see if you can find any sign of life off the phone in dmesg.
hope this helps some.
Sounds like a loose connection. Make sure that you've correctly reconnected all internal connections. Especially the connection under the little door with the void sticker on the screw in the battery compartment. If after verifying all connections are made and proper, the problem persists, I'm sorry to say you may have physically damaged the connectors during disassembly. Please visually inspect all connections for damage. A powerful magnifying glass is recommended.
(I have successfully replaced my digitizer twice, and my LCD panel once on this phone...)
Sent from my HTC Dark Raider using XDA.
I have taken it apart twice, checked all connections, and everything is good. Phone cannot enter any boot mode, and computer still doesn't recognize it. The orange light still only stays on for a few seconds when plugged in, then turns off. The phone then proceeds to keep trying to restart itself, but the screen remains pitch black blank
idk.. get a replacement.?

Screen Not Working

The Mrs dropped the tablet and the touch function of the screen stopped working. No amount of cold boots helped so I decided to pop it open to see if I could see anything loose.
I could see that the cable towards the top left (by the power and volume buttons) was loose from the motherboard so I put everything back together.
Now the screen shows nothing... I can see the light come on but nothing is displayed

Dropped and broke

Well a couple of days ago I was being dumb and swinging on some a construction thing and my phone fell out of my pocket about 3 feet off the ground. Well it landed on it's face and I picked it up thanking god my screen didn't shatter but I clicked the power button and it was all white with some vertical green lines. After about 5 seconds the screen goes black and my phone is just dead. I have no idea what's wrong with it but when I hold the power button when it is plugged in the home and back arrow flashes and the phone vibrates. It also does this if I hold the Power and Volume button but nothing happens on the screen. I need help diagnosing this to see if it is an LCD problem so maybe i can just get that replaced instead of the whole phone. Also, the first time I plugged my phone in to the computer HTC manager popped up but now it just wouldn't detect it. Help please!

My Nexus One screen not working after changing upper motherboard

Hi! Hope all of you are well
My problem is that about the title, I had to change upper motherboard because dead Power and +/- Volume buttons. Between my brother and I did the job, we put all in the same way the old mobo was, the phone charges until charge LED goes green as normal, the new Power button works because when I press it the phone does the typical boot vibration, but screen dead, it doesn't show nothing, even after waiting a few minutes until it fully boots the OS the Home, Menu, Back and Search buttons doesn't vibrate after pressing them
Any help and suggestions will be well received and appreciated
Thanks in advance!
