My start menu keeps blinking. Like its being touched but im not doing it. I can't use the phone at all. Its not the button itself and theres nothing on the screen. I think somethings wrong with the actual board. Not the mother board but board that belongs to the lcd screen and buttons. Is there any way I can buy just that board?

Hey all, I'm new to the forums but I can't wait to get my 8125 working. I bought a replacement screen on ebay and a broken 8125.. on receipt all I got was a white screen, then last night I replaced with the new screen and got the cingular logo and the windows mobile "touch anywhere to set up.." message.
Well, touching it did nothing, and the keyboard didn't work, so i opened it up again.
Somehow when I opened it up, the power switch button circuit thing detached from the mainboard (and it looks like the owner before me had actually crazy glued it on!!) .. and now the thing won't power up, won't show a charge light... nothing at all when plugged in or attached to my PC. So I hope that detached power button is the culprit. Upon further inspection I saw that yet another had detached but I can't seem to find where it landed... this one for the little button next to the slider, I don't really know what it does yet.. .
.. so I guess first step is to solder that power button back on and see what happens. Does it sound like a missing power button circuit thing would cause the unit to no longer power on at all (even when soft reset when connected to PC, which used to power it on?)

Argh.. well, i'll give it a go with the power switch.... do you think it will affect the phone to be missing the comm manager switch off the mainboard too... or will the phone still function without this piece soldered on?

Yes, the power on/off button being broken is the reason why you had a white screen, and only getting the splash screen after replacing the touch screen. If you're a good assembly man, I'd suggest try to solder the button back ln place or replace the device. As for the button by the volume slider, that's the comm manager button. If you can ever get to the homescreen, the comm manager icon to activate the comm manager (bluetooth, WiFi, etc. is in the system tray at the bottom of the homescreen.
It sounds to me the new screen was replaced improperly, accounting for nothing happening when you tap it.Try re-installing the replacement screen.

My son broke my LCD, so I took the device appart to replace it, but realized they sent me the wrong one. I put it back together with the damaged LCD, but now my red power button isn't working, and there is now a thin red verticle line aligned directly above the red button (slightly off center of the button to the right).
Is the red line a coincidence, or is it an indicator that my button is damaged?

Hello!
I have strange problem with my HTC HD2.
I doesn't power on without charger. It only powers on with charger plugged in to PC or wall and when soft reset button (under battery cover) is pressed. So it doesn't power on with power key.
When phone is powered on it shows only black screen with screen lights and key lights turned on. I can hear the boot sound from HD2's speaker so I think it boots into Windows Mobile correctly.
When plugged to PC and phone powered on, PC can recognize it. I have tried flashing newest ROM from HTC website but no change. Still black screen whole time.
Problem came after I installed new touch screen digitizer+LCD assembly. LCD ribbon looks OK and its plugged to motherboard correctly.
Could this be software issue?
I would be very happy if someone could help me with this strange problem.

It's not software, sounds like your digitizer to motherboard is messed up somehow. Worst case is dissemble and try again.

I have assembled and disassembled it again and again few times with official htc hd2 videos but no change.
Could this be radio issue?
sounds to me like the "front" face of the phone isn't properly connected with the motherboard and rest of the stuff.
FACT 1: the front power (or end call) button isn't working
FACT 2: the screen is blank, probably not powering on and/or receiving a data signal
FACT 3: the device appears to boot for all other intents and purposes
disassemble...reassemble...pay attention to the button strip and the LCD ribbons...maybe you might see something wrong.
Also, no radio or ROM would cause this issue, I don't see how this could possibly be software in any respect.
Disassembled and assembled again but still no luck. I contacted to ebay seller who sold lcd for me. He said that he will send me new lcd + digitizer assembly.
I am attempting to replace my Nexus 7 digitizer and LCD screen with one I purchased from gadgetfix on eBay, and I can't get the replacement screen to power on. Can someone advise me on things I can try to get it working?
I used a guide on Android Authority and understand that there's two ribbon cables that need to be re-connected (one that feeds through the body of the tablet, and one dual-connector that wraps around the side), as well as the power connector.
I can tell that the Nexus does power up when everything is re-assembled and I press the power on button. Plug it into my Mac, and Android File Transfer boots up. I think the digitizer is responding because when I touch the screen, it says stuff like "Welcome" and "English United Kingdom" (I'm guessing this is the Welcome language selection screen).
If I press the power button while it's turned on, it says "Screen off." Also, at one point it said "1:30am ringer 70 percent."
This is my second attempt at this - after returning/replacing the first one, I encountered the same issue. So I'm starting to think it's either my tablet or something I'm doing.
Any ideas? Thanks in advance!
have the same problem here... and many more out there...
bought new screen & digitizer from china phone accessories as recommended from you tube user... specifically requested for 3G model since it seems that different version has different screen...
fixed today, already checked the connection multiple times, but the screen wont show anything... there's power for the screen... is there anyway to workaround it... tried the power + volume button press but still no respond... since there's no respond on this thread for more than a year, it must be very bad issue...
would try to swap screen with my other unit but afraid the worst could happen, both unit wont show anything...
When I turn the phone on the screen lights up for about a half a second and show the logo. The phone fully boots and all buttons work. When I push the power button to turn the screen on it does the same thing. I can see that its at the home screen. There is no water damage and the phone hasn't been dropped. Sometimes I can get it to boot up with the screen working right. Is this a common problem? What is the cause of this, bad screen, mainboard, software?
Thanks
