My friend dropped his phone and everything but the buttons at the bottom of the screen is working, I've taken it apart and messed around with the ribbon cable for the digitizer but to no avail, any help?
If you try touch test apps and touch the area between buttons, does it react?

This is possibly a common thing, but the screen on my dopod has stopped being a touchscreen. Seemed to work sometimes, then stop, then start working again if i left it in the sun for a few minutes to warm up.. Have striped it down to see if it was a loose connector, but everything seems fine. D-pad and all the other front-cover buttons work. Is this more likely to be a screen issue or a ribbon cable issue?
Yesterday I was working on my HTC HD2, flashed WP7 Mango on it, and opened it again to align the plastic keys with the hardware keys undeneath. It didn’t really work out, so I carefully seperated the digitizer from the display to realign theglass abovethe keys. Now The keys work perfectly, but the screen doesn’t react anymore. I have no clue what could’ve went wrong, the digitzer flex cable is still perfect, aswell are the others which connect the screen to the motherboard. Anyone have a clue what could’ve went wrong? I hope it can get fixed easily
I’ll try to hold the ‘end call key’ while using the display. Seems like that will help to entight the connection.
Fix: So I took the Display out again and checked the connection of the digitizer at the back of the screen. It was loose. So i've put it in place and fixed the connection with some extra tape.
Hi my friend gave me her HTC wildfire to fix the digitiser as another friend dropped the phone in olive oil and well oil doesn't go well with the capacitive screen.
While trying to clean the capacitive part (which failed I'm going to have to buy a new screen) I managed to break the connector going to the front buttons the small ribbon cable the opposite side of the display and capacitive cable attachments.
So my question what does this cable do I assume that this only powers the lights behind them or does it also run the buttons?
Thanks.
It's just the lights, I broke mine when fitting a new screen. The buttons still work i just have no backlight.

Thanks that's what I thought, the buttons still work on occasion and are part of the capacitive screen.
Well to fix the screen now.
Thanks for your reply.
I replaced the keypad flex of my hd2 today after it was damaged while replacing the lcd/digitizer. Everything went very smoothly but now I have a problem. I was pretty certain when I was placing the new flex into the chassis that I did everything correctly but after I assembled the phone the buttons didn't work / I couldn't feel the "click" when I pressed the buttons, so I assumed I didn't put it right. I disassembled the phone again but nothing seemed wrong with the flex, it was perfectly in position.
When I try to press the buttons on the flex cable with a screwdriver, they work, and the phone boots up with no apparent problem. When I put the keypad on, they don't. Keypad was working fine with the old/broken flex cable.
I've been trying for an hour as to figure out what i'm doing wrong, but i'm at a loss now.
Any ideas?

replace also the keypad or you miss some part between the domesheet and keypad.
I've searched a good bit and wasn't able to find any information regarding the exact problem I'm having.
Bought a used G6 for starters
No water damage indicated by the sticker
The phone works great on the home screen and app drawer
I turned on dev mode to show touches
When you're in the camera it will stop responding to touches, you can still take pictures using the side buttons. The screen will become responsive again after a couple minutes. This whole time you can take pictures and the screen is functioning just not responding to touch
This happens also when you're loading web pages, even a Google search the screen will stop responding to touch and then eventually start responding again for a short while till you load another page or start moving around the page too quickly it seems. However again the screen is functioning, video previews are playing, just no response to touch.
Loading a game like Asphalt 8 the phone doesn't respond to touches until a couple minutes after the game has been fully loaded.
Even after a hard reset/factory reset the screen will sometimes be unresponsive upon the initial welcome/setup screen and then it will become responsive and you can go through the whole setup without an issue.
Any insight? Any suggestions? If I can't figure it out I'll just get rid of it but it's in great condition a shame it just doesn't function properly.
Thanks in advance!
Looks like some sort of hardware issue...
But before you start to worry...
This might sound like a stupid question but have you tried cleaning your screen with some cleaning solutions?
Sometimes dust mixed with dried sweat can cause severe touch responsiveness issues even if the screen looks like it's clean.
This is an older thread, but maybe I can help someone.
I replaced a touchscreen on a LG G6 and saw that the touchscreen did not work if the back cover was not mounted correctly and the data transfer between the phone and the fingerprint sensor was interrupted. This may be a common problem for users because the connector is small and the back cover is attached with a double-sided tape nearby this connector. It seems that the touch screen is disabled by the phone software without the back cover.

Thank you so much for this comment!
My gf phone had problems lagging and becoming insensitive to touch, the problem got worse and worse, almost never responding anymore. Performed a factory reset etc, didn't help.
After reading your comment I tried pushing on the back cover while swiping. Now I'm able to revive the phone after pushing hard on the top and bottom left corners, of the back cover.
Thanks a mille !
Lg g6 has back panel from glass and under it you have contact for fingerprint sensor.Somehow if the back panel is loose it can cause touch fail,and you cant use the device touch function!
--->FIX:
So you will have to turn screen off using back button,and then try to press back glass on left and right side of the camera lens !
Then simultaneously press the power button and try to use the touch .
If it does not work tru again around camera lens and turn off screen each time you press the back glass!
For me it worked !
