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!

A few months ago the screen on my SPV M600 took a knock which cracked it pretty badly, to the point it couldn't be used. I've rebuilt two other HTC phones in the past so felt fairly happy buying and fitting a replacement screen myself, along with the fact Orange wanted well over £100 for repairing it!
I dismantled the phone back to the screen to find it had a gold LCD cable and bought a new one on eBay.
I've now tried fitting the screen which works perfectly when the phone is still appart, but when I put the casing back together the screen goes blank. The exact point it happens is when I'm clipping the side of the phone with the volume control into place. The screen gets very bright as if the backlight is either getting too much power from somewhere or the backlight setting isn't taking effect. If I set the backlight to minimum it's most noticable as it goes from dull to full brightness when I apply pressure between the screen and board on that side of the phone.
I've tried sliding a piece of card between the screen and board to see if there was something touching that shouldn't be, but it doesn't seem to make much difference.
If anyone could offer me any advice on how to solve this I'd appreciate it.
Thanks.
I think I've solved it, I hadn't put a layer of the copper from the back of the old LCD onto the new one. It seems to be working fine now.
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
Hey guys,
I know this problem has been addressed before but none really leading to any resolve so I wanted to bring it to the surface to find anyone who actually has a solution.
I recently purchased a second-hand unit and found that it was working fine for a week until suddenly I couldnt hear voice in my calls. So I opened the unit and found that the contacts were off and fixed that but when the unit was reassembled, the screen turned white. Now I tried moving the ribbon connector of the LCD screen around and got different results: a black screen, a half black/white screen, a scrambled color screen. I hear that some say you can just dab some contact cleaner onto the contacts and it may work fine. Has this worked for anyone? If so where can I pick up a bottle? Are there other alternatives?
Please let me know.
Thank you.
just hit and trial may work for you as it did in my case.(i got a scrambled color screen)
just disconnect the ribbon wire and connect it again being exactly parallel to the slot.
ensure that it is pushed inside properly.
do it till your screen is tired of being messed up with colors.
tried that for an hour and I can't seem to get it right.
Does anyone know of a solution that can increase the connectors sensitivity?
Personally, I use rubbing alcohol on the very tip of a tooth-pick, then dry it off with a soft cotton swab.
I'll describe everything from scratch so you'll know what the problem is. So, I had 2 MDA Vario II, both developed a fault (on one when I pressed the button on na hardware keyboard it showed two letters on the screen instead, on the other the backlight under a couple of letters stopped working) so I dissasembled them and out of two faulty, I had one working and one working so-so.
As I wanted the other one to be sorted (the connector to the hardware keyboard was burned in some places on the mainboard and the keyboard tape connector as well), I was shopping for some faulty ones on eBay and yesterday I bought an original TyTN with LCD screen not working. I dissasembled both of them and connected the full LCD fascia with the screen to the mainboard of the TyTN (so that now I've got the LCD housing from T-Mobile, but the rest from HTC) and everything is working perfectly... however I'd like to use TyTN only housing and possibly buy a new one on eBay (but keys on the bottom are different for Vario II and TyTN).
I do know that LCD screens are incompatible, in the TyTN I have the HITACHI and in Vario I got the TOPPOLI (however the whole thing works with the mainboard, as both of them have the same product codes)...
But does someone know if I put the whole LCD from the Vario including the tape and top buttons in the fascia of the TyTN and connect it to the bottom buttons circuit, it will actually work. I will do it anyway, but if someone was doing it in the past that would motivate me to fiddle with it tomorrow
Sorted.
For all those with NOT working LCD screens/keyboards/mainboards...
As I the LCD screens are not compatible and we often do not know what we are going to get off eBay, lots of people face the problem of buying something that may not work with their version.
I needed the mainboard and the keyboard in my Vario II (HERM300) and I bought HTC TyTN (the original one, HERM200) with not working LCD (backlight working but nothing could be seen on the screen). As you may be aware that TyTN has got an extra button for 3G and Vario II not, I was wondering whether the whole thing would work. I replaced the full LCD screen with the tape including the two top buttons and connected it to the bottom circuit of the original TyTN. After assembling everything back, I switched it on and it's working without any problems. So if you have the same problem and can get hold of a cheap Hermes for spares on eBay, as long as you replace the whole lcd with tape it'll work regardless of your version...
Useful info thanks. That question was asked before and I don't think anyone gave an answer. Good to know it will work despite the different button layout.
cheers

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:
