Hey guys, my LCD broke, It was a AMOLED not SLCD, I bought this piece off ebay:
http://www.ebay.com/itm/260900702599?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I put everything back for the second time now, first of all the device doesn't come on, but when I plug the AC power it shows charging light.
I'm pretty sure my old screen is AMOLED..
I made sure all the connectors where tight on the board. any help?
It wont power on, did I break something?
I'm pretty screwed guys, been at it for like 5 hours I'm done for tonight
Here is what I've conluded. I detached the digitizer from the lcd I made a mistake and removed the factory "tape"
Is and in the process the little power button came off.
So what are my chances now?
Can the digitizer be taped back to the lcd? or Do I need to get a new digitizer which includes an LCD? so as to preserve the factory tape?
As far as the power button goes, I'm not talking about the plastic bit, I'm talking about the actual button underneath. It seemed to be holding on my a little thread anything. Is that "thread" a connector or the button functions fine without it? I put iit back and sealed the phone up, it seems to be pressing. But of course the phone wont still come on
Not even 1 person?

So yesterday my toddler son was playing with my Sprint Diamond when I saw him drop it onto the carpeted ground. The phone probably fell maybe about a foot but I guess the angle it hit the ground caused the battery cover to pop off.
When I picked up the phone, I noticed the screen was off and assumed it was in sleep mode because the battery didn't dislodge or anything. But when I pressed the power button, the phone wouldn't come on. I tried pulling the battery, hard resetting, etc but the screen still won't turn on.
While I was playing around with it, holding down the volume down button, power button and enter button at the same time, I could see the screen come on for a bit, then go blank again.
Physically there's no visible damage, there isn't even a scuff or scratch on the corners where the phone probably hit the ground. However, by some freak chance I think the fall caused something to go wrong internally, maybe the LCD digitizer became loose?
When I pull the battery and restart the phone, it vibrates as if it were powering up. But the screen never comes on.
Considering I don't have insurance on the phone, taking it back to Sprint is not an option and I'm out of the warranty period. Has this happened to anyone before? Any advice? Anyone have experience disassembling a Diamond? How hard was it? Thanks in advance.
the diamond (sprint) is a layered device.
you will need some very small screwdrivers lots of light and patience.
the screen is glued to the digitizer and the front housing, removal from the housing WILL crack it.
the boards and lower button pad con be removed safely, for inspection/reseating of plugs.
if the problem is not a loose plug,than a new screen and digitizer is in order and available on ebay from china
So...I took apart my Nexus One to clean the dust from under the screen. I've done this before, but it back together and it worked. But this time, after putting it back together it wont power on. I sometimes get a vibrate after pressing the power button. One question though. This time I noticed that one end of the coax cable on the left of the phone is broken and there is no plug on it. Would this be the problem? I don't think it should though since I'm guessing it connects the GPS antenna to the rest, and I dont use GPS on my phone. Any help would be good.
EDIT: I think I didnt connect the LCD good enough.
The co ax cable must be connected to the logic board. If it won't click in connect it then secure in place with a small piece of tape.

As I said, the top plug of the coax has been ripped off.
Do you know if that's the problem?
Again, when I push the button it vibrates like it usually does on boot, but doesn't show anything on screen.
I pulled out the board again, trying to find the problem.
EDIT!!!! I just noticed on the LCD ribbon cable there are a few bent pins. I think that will be my problem. I'll get it back together in like 15 minutes and report back.
EDIT 2!!!! So yea...two of the pins came off, and are way to small to find. Guess I need to order a new LCD.
Crap, new LCDs are $60+
Hey guys,
The USB port of my HD2 broke off and I was forced to replace the motherboard. When I assembled the HD2 again, I could immediately see that there was something wrong with my screen. The screen couldn't display full color (only bright red/orange/white/dark green/cyan accents). Also, the 'hang-up button isn't responding anymore after I replaced the motherboard (and flexcable).
What happened? Is there something wrong with the lcd display or did something go wrong when I (dis)assembled the phone? I took the motherboard and the flexcable from another HD2 that had a broken display.
Thanks in advance.

So you completely voided your warranty through HTC and tried to fix the device yourself, then screwed it up. I'd still say send it to HTC and ask for a repair. I don't know if they'll do it or not, unless you used official parts. I know they do out-of-warranty repairs, but they'll charge you.....
Yep you screwed up the repair, those ribbon cables need a delicate touch & any handfisted moment ends up with what you have got now ...
Another careful strip & inspection of all ribbon connectors is needed ...
I bought it as a second-hand phone. The guy didn't give me a reseat and the HD2 was flashed a WP7 ROM.
For the button problem, how are you turning your phone on without that button? do you hear/feel it click when you press it? If not its just misaligned.the buttons are on a flex ribbon cable with two holes on each side. it fits on the plastic middle frame of the phone which has two small spikes coming out of it... it has to be perfectly placed for your buttons to actually click..
if the flex ribbon is broken however you can buy one off ebay for arround 10$ any will do, mine is not original works fine..
for the screen you could have messed up the lcd, did you separate from the glass-digitizer? if you did you probably screwed it up.. its not a easy thing to do.. also was not necessary for your repairs
the connection to the motherboard might not be all the in and clipped which might cause your problem... (being that two of the little pins provide voltage and ground while all the others provide data information if one of those pins is not in all the way a piece of data might not be displaying for example a color. Never seen that happen its theoretically possible thou)
well I have only opened my phone 3 times and dont claim to be a expert.. but this is my take on it... Good luck!
@pablow Thanks for the detailed response.
The HD2 is only turned on, after I place the battery. Otherwhise it won't start.
I hear a click on the (broken) 'off' button, everytime I press it. I also noticed that the inside of not all of the 'spikes' are empty. I can see a bit of the flexcable in the spike of the broken 'off' button. The spike of the (working) 'call' button is empty.
I think that the flexcable hasn't been connected securely to the motherboard. I'll try connecting everything again tonight.
not that it makes much difference but HTC wouldn't of fixed it through warranty because of usb damage anyway
I thought so, thanks for the heads-up anyways.
[Solved] Display is fixed
Update:
I disassembled the HD2 and reconnected everything (from coax to flexcable). Fortunately it worked! The display is how it should be.
I have another problem now. All of the buttons don't work now, exept for the dial button. Do these buttons break so fast? It's annoying as fuark, because I have to disassemble it another time in the future to fix the buttons.
I also couldn't re-attach the volume control tab when assembling the HD2.
Hello, guys!
Recently I bought an HTC One with cracked digitizer, but functional. It had a lot of scratches etc, but this is not important right now. I wanted to do a complete make-over so I bought replacement parts from the internet, I bought the front housing with the LCD screen and the back cover. I dissasembled the phone from the old housing (the one with the broken digitizer), and I assembled it back on the new housing. After all of that, I powered on the phone and it worked like a charm (the LCD and the touch-screen worked perfectly), but then I saw that the glass was a little out, I mean it was upper than the speakers cover, so I decided to take out the whole screen and to change the adhesive, because it was too loose and the screen wasn't staying properly. I succesfully did that, i put the screen back and everything was good, but when I wanted to start the phone, the screen remains black. And this is the problem I have. I mention that I worked very carefully with the screen, so I don't think the problem is at the screen. I disconnected and reconnected all the cables and still doesn't work. When I press the power button it vibrates and then it's making that sound like the phone is booting, but no image on the LCD. If I keep the power button pressed, the back and home buttons are blinking and then the same story as before, vibrates and then the sound. I really don't know what could be the problem.
I really need some help with this and I'm open to all of your suggestions. If you want more informations feel free to ask.
Thanks in anticipation!
To me it looks like you damaged one the flat flex cable.
When you took the screen out did it come like suddenly and maybe some tension was applied to the flat flex?
If I were you I would take it apart and verify the connection in the socket, maybe the socket was damaged or something and it doesn't make a good connection
I hope it works out for you
Thank you for your answer!
When I took out the screen, I took it out very carefully and there wasn't any tension applied to the flex cable, so I don't think this is the problem. I think it's more likely a problem with the socket on the motherboard, like you said, and it's not making a good contact. But what can I do about that?
long story but i was trying to fix my rear camera lights and opened the phone up. when i popped off the volume/power ribbon from the mobo, it popped the part of the mobo the ribbon was attached to as well. i don't if i had a dud of a phone but there was literally no way in hell it was going to stay on the mobo because it was on the ribbon TIGHT and like connected to the mobo by a drop of glue. zero resistance when it came off.
anyway can i hook up my phone to my computer and boot it that way? surely there has to be a way to do this without the power button working.

There is a YouTube video on how to replace the power button and when he removed the power assembly you can see there is a small silver pressure button which is what the plastic hits. If you can touch and hold that with a pin it should start up. If it doesn't power up by depressing the silver button then you are going to need to replace the assembly itself as shown in the video. Keep the buttons though, I don't think they come with the power and volume assembly.

i put it on my qi charger and it booted right up, if anyone is curious
