Hi all,
I wonder if anyone can help, I recently returned to the HTC scene. Someone gave me a HD2 with a smashed screen Digitiser, everything else worked fine.
I got a new digitiser/LCD, fitted it ok. Now, back together, although there are a few really strange problems. There is no sound at all, either through the speaker or the ear piece, the vibrate doesn't happen and the volume button doesn't work.
Is any of this connected, I can't work it out.
Thanks in advance for any help.
Cheers
Andy
All 3 mentioned are on main flexboard, therefore, IMO, you have a problem with main flexboard or its connection to motherboard: check carefully connector and related portion of flexboard.
Good luck!
Cheers pal, took it back apart and the main flex was slightly out!
I checked that as well, thanks anyway.
Glad you got back in business your hd2!:good:

Hey people, I think I have a great problem with my qtek 9000 or mda pro, I have bought from UK and it worked fine, my screen got extremely turned to right so looks like the wires got cut at the point where it turns. The sound didnt work, the touchscreen unsensitive and the screen where at black and white, I soldered the wires (only seven) and now the color is back again, but the sound and touch system remains disabled, Can some little device be damaged because some wire touched other? I think the problem is nearly the screen connectors, I have tried to use the jack stereo to try if earphones worked but they didnt.
I need help people, and now after buying the device I have no money enough to repair it, could you someone advice me how to repair it?
Thank you!
I just dropped my qtek S200. When I turn it on noe, I just see colored stripes, but the qtek seems to work normal, because if I use the camera button you can hear the "click" sound e.t.c.
What shall I do know? Please help me - I am quite in Panic know .-(
Please anyone?
Did the display cable come loose? You'll have to open the unit in order to rectify this. As I have just ordered a new case, I have searched for instructions how to do this and found
this step by step manual.
Good luck

Thank you very much for your help - I will try this out. I hope I can open it, because I am not very good in this.
How does the display cable look like?
I got stucked at this step: NOW CAREFULLY LIFT THE BACK COVER AWAY FROM THE FRONT AND NOTE THE SHORT SPEAKER CABLE, USE YOU TWEASERS TO CAREFULLY DISCONNECT IT
How do I disconnect it??
What exactly does the device do? Does it respond to charging? Does the screen have any response to being switched on?
The qtek works properly - that means I can use the com button and touch the screen where eg the bluetooth used to be and I can turn it on.
The camera button works too, because you can hear the click when taking a photo.
The only thing is, that you can only see vertical colored stripes on the screen that change their color after some minutes.
I just opened it now, but it did not help.
you have to buy a new one hahahaha
I got a htc 8525. i can see everything perfect excepct the fact that the lcd screen doesn't light up. so basically im looking like a owl trying to read text n whatnot. Any ideas?
Had the same problem, replaced the flywheel when repairing my hermes, IT WAS THAT!!!!!
I couldnt tell you why it caused the problem but it did. Used the mainboard of 2 Hermes to test and it WAS the scrollwheel that caused the no backlight problem. Was kinda relieved as the mainboard in my old jasjam was bloody brilliant and quick, the new one was kinda slow. So, back to the old mainboard.....YAY....
Cheers....
i can confirm this - got my hermes in pieces in front of me, trying to fix the white screen / dead d-pad problem. did a power-up test while it's still in pieces and forgot to re-attach the scroll wheel, backlight didn't come up. searched and found this thread, tested again with the scroll wheel in place, and it works fine.
I have the same problem with the screen, it doesn't light up. It is working fine except the back light. This happened after i dropped my hermes and since then no back light on the screen. The flash also doesn't work when i lunch the camera. It only blinks on start and then nothing. After reading the post i removed the scroll well and turned on the device but again no light. Should the screen work without the scroll well? Any ideas??
It won't work without the scroll wheel board removerd, it HAS to be replaced with a working one.
You need to find a working scroll wheel board.
Cheers...
Thanks for your answer. After reading the post i kept trying to find a solution since i knew what the problem was. Finally i used a spray to clean the contacts on the motherboard and the scroll wheel and all other contacts on the motherboard. Then re attached everything in place and the screen now works just fine. Thanks again!
Hello! I have recently installed CM9-20120319-NIGHTLY-jordan on my Defy and it seems there's a problem during calls. The proximity sensor is not working (when I'm taking the phone from next to my ear, the screen won't turn on, as it used to before in the CM7). Also, the screen remains black and won't turn on unless the other party hangs up the phone. I need some help about how should I fix this. Thank you!

Ok, I know this is really old, but I just had the same problem and want to document how I fixed it cause this is a top search result for me and I figure it must be for others too. I had observed this behavior just after installing Quarx's CM11 Nightly, and I had assumed that it was a software glitch.
Some months ago I actually managed to crack the glass on my phone, and I had ordered replacement parts. I thought I had just ordered glass, but I got a whole new case that was all shiny and new. So I swapped broken parts for new and went on my merry way. But I did notice that the volume down button was sticky, but I just dealt with it for a while. Recently when I was Rooting and installing CM11, I got frustrated with my volume down button trying to get into the recovery system, so I cracked my case open to take a look at the sticky button. I found a small plastic burr left from the molding process. I sliced it off with a razor and reassembled and thought nothing of it. Happy with my functioning volume down button I proceeded along my merry way.
Now, why was this detail in the story important? Because in between Froyo and CM11 I had inadvertently caused my proximity sensor to malfunction, by tightening the screws too tight when I put it back together. It wasn't CM11; it was me. The fix was easy. Pop off the battery cover and loosen one screw a half a turn at a time until the proximity sensor started working. Pro Tip: Dial into voice mail while trying this so you can have an active call without hassling your brother.
I only know this now because I found this video:

OK guys looking for community experience. My defy took a tumble and cracked the screen, the only thing holding the glass was a screen protector. I bought a screen from eBay and replaced it myself. All went well till I started getting complaints that callers to me just hear themselves back, now the complaints started first call after replacement screen and with every call since. Anyone got any ideas what might be wrong?
The only logical reason i can think for this is that somehow you managed to put something out of place when you assembly the phone back... did you try to disassemble and try again?
Sorry that a don't have technical skills to give a proper answer, but that looks logical!
Good luck!
It might be echo cancellation mic, maybe contacts aren't set properly on the board. Try to call with headset, it should be no echo.
When i'm holdnig my phone on my ear with my shoulder people are telling me that they hear themselves...didn't investigated that to find culprit, but it is surely because echo cancellation mic.
P.S. And don't call me Shirley
Hello,
I have exactly the same problem. This was my second replacement. The first time i just replaced the glass digitizer leaving my old cover along with the original buzzer. No problems there. The second time though i decided to order the whole thing all together (cover, digitizer, buzzer) in order to same myself the trouble of unsticking the glass and removing all that adhesive glue.
Unfortunately since my second replacement every time i make a call, the person i 'm calling complains about echo and hearing himself. I 'll try to replace the buzzer with the older original one i have and i hope everything turns out good.
Do you have any tips for me, have you solved your problem @rydroid?
any resolution
Hi, did anyone get a resolution to this problem? I have also replaced teh entire front cover and digitizer and am noww getting the same problem. I have double checked everything is installed properly which it seems to be. i think that maybe the noise cancellation mic is being pushed too hard onto the back cover or something.
Anyoen get it sorted?
Cheers
Chris
Guys,
Here comes the solution for my particular echo problem:
I got the same trouble with my girlfriend's phone. Few days ago I replaced the digitizer and since then when I was calling her phone I heard my own voice in my phone back with a nice echo effect. I took the phone apart again to separate the voice of the speaker from the microphone somehow and in the meantime I accidentally lost one of the yellow rubber rings. It fall down to the floor. When I was looking for it on the floor I just found it and I also found another yellow part that I was most probably lost few days ago at the first round. When I put back all the yellow parts and tested the phone again this time the problem just gone. So the solution for me was putting back the yellow part that is located around the bottom of the phone that seems to be isolating the voice that is coming from the speaker. This part is only visible if you take the phone apart in a way the only the LCD and the screen is together in your hand. The mentioned yellow rubber can be seen on this picture (which I just picked by google-ing some random picture): LINK. It is the one seen on the part that is on the bottom left corner, under the LCD, on the left side.
I hope this helps other to resolve the echo issue.
Cheers,
Adam
end of my woes.
I had the same thing as adam in the end. its the little orange silicon bit that shields the microphone. it fits into the fornt cover near the microphone hole. I accidentally threw it away with the old cover and then had the problem. I had to buy a complete new casing in the edn but it is working fine now.

Hello,
I had the same echo issue.
I have to thank you very much Adam, because I also lost mic seal when I changed touch screen. And I had a big luck, because I found it on the floor after 1 week!
Once again thank you
I am happy to read that it helped you, Hark33. That was the exact reason why I wrote it down. :good:
Cheers,
Adam
