I have recently replaced the screen in the Jade after dropping and cracking the previous screen.
After replacing the screen it turns and and all looks fine but the digistiser does not work?
I had some problems with the white clip (see photo) and removing/replacing the ribbon. Is this the ribbon that controls the digitiser? if so i guess this may be my problem.
Any ideas would be appreciated
Did you flip the cable after you placed the digitizer in the casing?
like this:
click
otherwise, the cable is upside down in the connector.
i had the same issue.

Hi
Forgive me if this has been posted before, but this is my 1st post here & need a little 1to1
My touch screen on my Qtek 9100 stopped working a few days ago, the phone is ok, i can make calls & use the manual keypad.
The phone was left uncharged for a few days & when i went to use it again the touch screen was not working.
There is a dent in the screen that i did not notice before, its only about 1cm, actually its more of a scratch than a dent.
The screen looks fine, no cracks or black spots visable.
No life from the screen, whatever part i touch.
Can someone advise me on what to do to get back up & running.... I have already done this.....
Hard & soft resets
Installed latest ROM.
Phone is currently stuck on the the "touch screen to setup your mobile device screen"
I have already ordered a new touch screen from the net,
should i just change the touch screen or are there other things to try first?
Any advice welcome like

Cheers
any luck? im having the same proble but with my atom exec and everyone seems slightly blank on this
When the touchscreen went bad on mine, it turned out the cause was a tiny, almost invisible hairline crack in the touchscreen's ribbon cable which severed one of the wires. I had to use a magnifying lens to see it.
It was possible to test with a multimeter. On the back of the LCD is a piece of clear tape covering where the touchscreen ribbon is soldered to the LCD. You will need to lift the tape to expose 4 wires from the touchscreen. With pressure on the screen, there should be a resistance around 1.2kohms between pins 1&2 and the same between pins 3&4. On mine, pins 3&4 were open circuit.
To fix mine, I didn't change the screen. I removed the touchscreen ribbon from the main LCD (accidentally tearing the solder pads off the ribbon - I wasn't sure how it was attached). Then I used an X-acto knife and scraped off some plastic from each side of the break. Then I soldered a TINY piece of copper wire no thicker than a hair across the break (a single strand from a stranded wire). Since I accidentally tore the solder pads off the ribbon, I scraped off some plastic from the copper traces there and soldered some wire to them and soldered that to the LCD. That did the trick, it's all working now!
i have this same problem.. i was using the qtek with the cracked digitizer but when i did the hard reset it took me to this screen. is there anyway we can get off this screen? help plz!!
Hello all,
My Touch HD slipped from my hands and ended-up flat on the screen... the screen does not have a scratch, the digitizer still works perfect, but the LCD underneath is broken, so I get a black screen. I can still access the Touch HD via my PC thanks to MyMobilier, though (so why do I complain, huh?!!)!
I ordered a replacement LCD in Hong-Kong (thanks ebay!), got the HTC Service Guide, managed to remove the antenna cover (tough!) and dismantle the whole thing. But NOW I AM STUCK with the 'bezel', i.e. the cover, screen, digitizer, LCD, and metal plate with bolts all apparently glued together.
Anyone faced the same problem? Anyone knows how to separate the LCD from the screen and digitizer?
Cheers,

Anyone can help with this???
Hi, I have G1 with touch screen not working. On the back of the LCD, the small clip down connector for touch screen ribbon cable doesn't seem to grip tight. Even when closed, cable can be pulled from connector quite easily. Any suggestions please?
i cracked my digitizer a while back, and ordered a replacement. i used double sided tape to install. the first digitizer worked great, except only the top 10% of the screen was not responsive (pretty much the width of the task bar) so i contacted the people i ordered the new screen from, and they just sent me a replacement. i installed the second digitizer, and this time none of the screen works.
i tried to make sure both times not to put the tape to wide so it doesn't overlap into the clear screen part, only the black, but could this be a tape issue? anyone else have trouble with installing where parts or entire screen didn't respond?
thanks for your help.
Are you sure you have the digitizer/lcd ribbon in all the way to the connector on the motherboard? When I first put everything back together when I changed a digitizer, touch didn't work at all for me initially. At first I thought I had a bad digitizer. Then I looked closely at the ribbon and connector, and there's some flaps that stick out to the side on the ribbon cable. Make sure you push the ribbon in until the flaps stop you from going any further.
Hello,
I replaced the digitizer and LCD on my 1st generation Nexus 7 with an apparently identical Hydis LCD/digitizer assembly. Now I am experiencing erratic behavior of the touch screen, some dead spots, scrolling registering as touch, etc.
Could this be a grounding issue that happens now because I did not properly put the unit back together? If so, which areas should I focuse on / cover with electrical tape to try and get rid of the issue?
Could this also be a software issue if the lcd/digitizer model is not exactly the same? The numbers below the "Hydis" markings are the same as on the original unit, but the numbers below the code bars are different. If so, is there a solution? Drivers? Calibration?
Thanks in advance for any insight.

Turns out I had not fully reinserted the digitizer ribbon connector into the mobo clip connectors. The white lines on the ribbon connector should be exactly flush and parallel with the black part of the clip connectors, and you should hear/feel a light click when they get fully inserted. Works fine now!
