Display is working fine, but when I tried to use stylus, touch panel didn´t response.
Could you please help me, where should be problem?
Check the connections of the flex cable, found out the hard way that it has to be just right or it may not work.
Test it before putting all back together so you can experiment.
Cheers...
There are many cables... Which one is for touch functiron?

Hi
I have a Qtek 9000 and recently I broked the display. As I had the service manual I thought I coud replace the display by myself. I bought a new LCD + touch screen on ebay and the replacing of the LCD was easy and went quite well. The lcd works fine but the touch screen don't. I cheked and clean all the contacts but couldn't make the touch screen work.
So I wrote de seller and we agree to send back de display and receive a new one that he will test bofore posting.
I placed this new display and the problem remais the same. The lcd works fine but the touch screen don't, so I think the problem could not be here.
I made a hard reset and even downgraded to the original ROM but the touch screen still not working.
Can anyone help me with this
Thanks
Have you tried the touchscreen side of things before re-asembling the casing?
I have had problems with the seal on the casing around the screen activating the touch screen permanently - so that it runs really slow (if at all) when using the keypad.
damn, did you get the touch screen to work at all?
which LCD + touch did you buy from ebay? hopefully we can avoid this seller and get something that works.
ever thought of buying the touch screen separately and putting that on?
Let us know how it goes.
whitemoo.
after disasembling/asembling device had the same ussie with touch,after a cup of hours using it.
armandoramos try to open,when UNI works,only a part of UNI with LCD(look page 21 in service manual-bottom picture,page 22 & page 23-middle picture),then try how works your touch.If it works-you just had pinch the LCD coaxial cable module.
i had a problem with my touch screen, i was lucky enough to find a second hand uni in a local market with a busted lcd but working TS.
i swopped over the TS and re-assembled my uni, one thing i did have to add was a tiny piece of foam between the ribbon cable assembly and the case, this was to push the two ribbon cable sections (TS and LCD) together, for a better connection, relying on the sticky bits alone was not enough.
hope this helps.

Hi all, my Hermes/JasJam LCD screen and front panel stopped working a while back with the whiting out issue, funny artifacts and non working buttons. I have pulled it apart quite a few times to make temporary solutions but none have lasted enough.
So now I'm looking to buy a used Hermes and jack the screen part off it and place it on mine. Now I know how to do this but what came to my mind was:
Buy the newer version of the Hermes and place it's front part on my old jasjam which would be like a mixed/modded Hermes.
So I saw the O2 Zinc and the TyTN II and i really like the front panels better than the original hermes ones. So, before I buy one of them, does someone know if the ribbon cable is the same as the original one that connects to the phone's mainboard?
Any help much appreciated!
Today, when I was switched on my Nike and tried to write my SIM cards password, I realised that touchscreen is not working. I tried to press various places of the screen but with no luck I made some reboots but again the same luck... so propably is not software problem. It's very difficult to use it only with it's keyboard and it looses its usability :S Is there anything I can do to fix it up???
Recently I came onto the same problem, at first the screen didn't work and then the screen just became black.
I opened up the phone and saw the flex cable had been scratched, so I bought a new one at ebay, replaced the old one, and wolah... worked like charm. Got my old phone back, installed a new 6.5.3 ROM and I'm LUVIN my "old" HTC.

I bought mine in Iceland, (Europe) but I think that all the flex cables are the same in all versions of the phone.
Thank you for your advice
Thank you for your advice,
I didn't manage to change the flex cable yet, because the touchscreen started to response again, but just for 3 hours... Now it does not response again. The screen now displays everything fine, but if I touch nothing happens. I can only use it by the keyboard. I heard that in most chases, scratched flex cable turns screen white or black, it doesn't affects the touch(screen). But I'll give it a go
So I bought a HD2 with bad touch screen. The issue was the very common one that every one knows, red button that was poking into the touch screen flex cable. I opened up the phone and fixed the issue and touch screen was working perfectly fine. In the process, unfortunately, I chipped a little edge of the front glass/digitizer. It was not a big deal as phone was still working fine. But I decided to buy a new front glass.
When my new front glass arrived, I separated the digitizer/front glass from LCD, but then half of my LCD got corrupted. So I ended up buying an LCD too!!!
Now comes the issue: when I put the phone together, touch screen doesn't work at all. I have tried all combinations of NEW / OLD digitizer and NEW / OLD lcd. Nothing works. I wonder if anyone can help me figure out why?
P.S. When testing, I happened to connect the phone to my 5w wall charger directly connecting it to power pins (without battery installed). Would that be why I lost touch? Is the touch issue now because of motherboard that was directly connected to adapter, not getting power from its designated battery?
have you tried the old lcd with old digitizer (which was working)?
tried it before replacing?
did you made some change to the software before replacing?
I currently have this problem too while trying to revive my old- almost 3 years inactive- HD2 with new touchscreen, and still trying to figure out where is the problem

Yes I had tried the old LCD, and that didn't work either.
I installed a WiFi Keyboard on it.
Did you resolve this issue?
