Screen unresponsive to slide-out keyboard - XPERIA X1 Q&A, Help & Troubleshooting

Hi all!
Yesterday, my X1 started behaving weirdly for no apparent reason. It simply stopped responding when I slid out the hardware-keyboard (i.e the screen didn`t "flip").
Secondly, when I write with the hardware-keyboard there doesn`t seem to be any response until I slide the keyboard back in, and everything I wrote appears on the screen. It started happening spontaniously, and did several hard-resets and ROM flashes to no avail.
Anyone else experienced this?
Thanks in advance.

Yup, I did
It is a hardware problem (flex cable)

Touch screen problem

Quite a few times during the last week, my Diamond's touch screen has stopped responding for no apparent reason. The hardware buttons work just fine, but the screen gets me nowhere. It works fine after a soft reset, but I've had to soft reset it several times some days, which is seriously annoying.
Is this a familiar problem for anyone? If it is, does anyone know of a solution? I tried searching around the forum, but couldn't find anyone with a similar problem..

Touch not working.

I recently upgraded my kaiser with a cooked ROM (shifu 10) radio 3.34 i guess. It worked good. After some days it started giving problem with touch. The right soft key was working continuously without even pressing it. When this happens the power button also stops responding , so i have to pull out the battery to turn of the phone. Then i loaded it with original HTC ROM WM 6.1 radio 3.28/3.29. it worked fine for some hours then the problem re appeared. then after some hours the lcd stopped responding to touch , it responds sometimes.. The keyboard worked fine. Then i went to HTC customer care center. They said LCD needs to be replaced. After getting the LCD replaced the problem persisted. what could be the problem???? Please help...
Have you tried...
Have you tried realigning the screen found in setting/ screen/ align screen?
I had an issue similiar at one time, my stylus really wasnt working well at all i was having to push hard with my fat fingers for touch to work. realigning solved my problem. Worth a try.
When i re installed ROM, i couldn't align the screen properly as it was not responding to touch. I'm sure it's not screen alignment problem. Why didn't touch work properly even after LCD REPLACEMENT?
Check this out. I believe this is your problem.

Touch screen problem.

My kaiser's touch screen suddenly has aquired an attitude. Some time it works, some it doesn't. When I touch nothing happens. Also when I slide open the keyboard, it works, but as soon as I close the keyboard, it stops working again. When I reboot, the screen works, but it stops after some time. Then it works if I open the keyboard. I have done hard reset, but that hasn't solved the problem.
Is there any thing I can do to fix it.
Now the touch works only if keyboard is open and doesn't work when closed. Any tips (already did hard reset twice).
With more research, the touch screen works but only when pressed very tightly at the point shown in figure (See red circle). Is there any solution to this ?
Will this get fixed if Change LCD ? Or can it be fixed by tightening some screws ?

It's a hardware problem, your flex cable is worn out.
Dear harveydent,
Keybord is working but not showing in display. after opening keypad screen gets stuck & not rotating, & after closing keypad screen shows exactly what I typed on it.

I didn't say your keyboard or screen was broken. I said the flex cable was.
The hardware problem is the cable that connects your keyboard/main unit and lcd screen together (the flex cable). So your keyboard 100% works. Your screen 100% works. But when you slide open the phone, the flex cable stretches. Since it's worn out, some connections break when it stretches the main board can no longer send signals to the screen, so it appears to freeze. But the keyboard (and everything else) still work, so you can still type, only YOU CAN'T SEE IT since screen can't get any signals from the board. When you slide the phone back, the connection is restored and you can see what you typed.

[Q] HELP!!! very weird problem!

i have this very weird problem that happened to me a couple hours ago. i was checking a GV text and when i closed the keyboard, it seemed like the screen just died. i thought it bricked, but fastboot worked. i found out that it would do the "screen death" when i closed the keyboard. so basically, it only works when it is landscape; keyboard open so to speak. when i go back to portrait it "dies". can anyone help? is maybe because the lines inside are messed up? HELP!!!
*****solved. BAD SCREEN RIBBON*******
