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.
Ok I need help from the gods of xda
I dropped my tilt the other day. When I picked it up everything seemed fine, yet the screen was completely white. No signs of cracks or a broken lcd. So I've tried the following: Soft reset, Hard reset, took out the battery, took apart the phone and disconnected the lcd and then re connected it. Still the same problem. WHITE SCREEN!
I can still receive/make calls, when i touch the screen in places where i remember the menus to be it still responds due to the noise, also the open and close noise still sounds.
The phone was bought new on Ebay, so i don't have a warranty through them or AT&T. After much research I hear people saying the same has happened to their phones as well and that there is a ribbon or flex cable problem. Something about still giving power to the LCD but not data, thus the white screen.
Now what I dont understand is do I need a new LCD because it has that ribbon/flex cable on it???? (link)
or
Do I need this product?(link)
Both contain a "flex cable" so im confused and frustrated, someone please help! any ideas would help

hi there, would it be possible to post the link to ebay item? i also need a new touch-screen.tnanks
I am curious about this as well. I have a friend who has a hermes and he mentioned to me that that his screen was starting to go white like explained here. I look at his phone and I also noticed that the bottom hardware keys were not working at all.
I am wondering if this same ribbon cable for the LCD would also be the same one for the bottom keypad and if I fix the screen the keys will become active again.
Anyone have any experience with this?
Thanks,

Tuck in for a long read and perhaps no single answer for all cases:

In short, yes the d/pad cable and LCD screen connections are linked which is why it is not uncommon for the white screen to show up when the d/pad is not working.
To the OP - I would just point out that if you get the white screen after a fall it may just be a loose connection at the d/pad and no need for new parts.

But let's not start discussing the white screen here, please use the first link I gave above if you need to post.

I have SPV M3100 and few months ago I broke my display so I bought new one from ebay
(http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&Item=300256442884&Category=20336&_trksid=p3907.m29&_trkparms=algo%3DLVI%26its%3DI%26otn%3D1)
and there is not working touch panel after I replaced it.
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.

There are many cables... Which one is for touch functiron?

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?
