[Q] Xperia T, same screen problem as X8, X10 and so on

Hi
Quick question. I don't know if anyone experienced that with Xperia T. I seem to have the same problem with it as with previous X8 and X10. Screen stays blank after switching on. Just backlight comes on but nothing else. Touch panel still responds as it should but no information visible phone is kinda useless. Just wondered if anyone knows how to fix this. Would it be hardware problem which seems to be going on for quite a while then in sonys mobiles or is it just software glitch? I would buy new screen but not sure if this will fix it.
Phone is updated to latest available firmaware. Done it yesterday with SUS.
Thanks

First I have heard of this probelm, so it sounds like just you.
Use PCCompanion to fix phone.
HAve you flashed anything to the phone, have you rooted it, have you unlocked bootloader.....

PC companion stops half way through the process. I've used the other standalone sonys update service to upgrade the phone which has done it no problem but still nothing visible on screen. Only brightens up slightly when switched on but nothing whatsoever visible.

Hi
Sorry, forgot to add earlier. No, nothing was done. No bootloader unlocking, no rooting, no other flashing. It just happened when I switched it on couple of days ago. I did have same/similar problem with X10 some time ago but along with just backlight on the screen (nothing else) but phone was in boot loop at the same time. This one just stays on for whatever time you want it and you can hear sounds and feel vibrating when using touch panel. Just trying to determine if it's something simple like faulty lcd (not cheap at all thoguh) or even if I splash out for a new lcd it will not help.

If you have not flashed anything, take it back to the shop for a new one

Hi
Yes I did. Fitted new screen! Only £160 pretty much the same as new phone now.
Was your phone damaged in any way (spilled water on it, dropped it)?

No man, she just was charging it up, then she plugged it out, and after that it was working but with the screen off , so is it a hardware problem and not software problem?

In my case was hardware. In yours might be not. I'm not that much of an expert so my only suggestion would be to do hard reset. Did you try that? Hold power button for about 15-20 sec.

I just have reinstalled JB Stock ROM and nothing, the Display is death, the weird thing is the Digitizer works, i can even hear when i touch the buttons, anyway thank you.

Would it be strange to suggest you should contact Sony for warranty?

[Q] Touch screen not responding in the middle

My Incredible S has a touch screen fault. There is a area in the middle of the screen that does not respond to touch - see attachment.
I have fitted a new digitizer screen thinking that would cure the fault, but unfortunately the problem still remains.
Does anyone know what causes this and is there a solution?

hey
i had the same problem except that my UNTOUCHABLE part was horizontal
anyways;
i read on several pages on net that digitizer needs to be fixed
but i asked an expert at service center and i was told that i need to replace a touchpad and screen both NOT the digitizer
i did it in INR2000 and now my INCs runs flawlessly and smoothly

Thank you prunzzz for your response. I was wondering if replacing the lcd/digitizer assembly was the answer and now you have confirmed it I will go ahead and order one. :good:

Hello!
I am having the exact same issue (middle portion of touch-screen not working - horizontally) I was looking for a solution, and found your helpful post. Thanks added, can you please tell me what all did you replace? Just the digitizer?

Same prob as yours

I am sorry if its a silly question

[Q] Unable to swipe down the statusbar

I've been having problems with the sensitivity of the top 2mm of my phone's screen. I don't remember when it started but I think it was around a couple of months ago.
Before, it was only difficult for me to swipe the notification bar down, but now, I can no longer swipe it down unless I rotate the screen.
I don't remember how or exactly when it started, but I remember that I was using ARHD 70.0, then I updated to 71.1 in attempt to fix it, but it only worked for a while but it came back again. I also tried other roms such as MaximusHD and Eragon but still the same. I also tried rebooting to safe mode but still the same. I also used both stock and elemental sense kernels.
I updated my firmware back then to 6.06 and now to 6.07 but still nothing. I haven't tried downgrading yet though.
I tried using the line draw test and the result is found below.
Does anyone know how to fix this? I already searched xda and google but i found no solution to my problem.

It could be a hardware related issue. If it's still under warranty revert it to stock and re-lock the bootloader and just send it back.

Has your device been dropped or been water damaged? The digitizer connection from the mb could have became a bit loose.
*Edit*
I have read on a forum for the HTC One X which seems to have a similar issue to yours where a part of the screen is unresponsive. Someone suggested to clean the connector.

I dropped it a few times while in a case and only around a feet at most. It never been water damaged, hopefully never will.
I see, I'll look for it there, though I'm not sure how to clean the connector. Thanks!

I did some more research about it and people are saying it is a digitizer issue. So replacing the digitizer should fix it, but you will need to buy the lcd and digitizer together as its nearly impossible to replace them separate from eachother.

It's definitely a hardware issue. I have been dealing with the same issue for about 6 months now. When I try to swipe down to bring up the notification bar I get absolutely no feedback . If I give it a smack with my palm near the top corners I can often times get it to start working again. However, it's usually short lived.

I see. Thank you very much for the help. I think I'll just send this to the service center when I get the chance. I will probably ask them to fix the red tinted camera as well. I just hope it won't be too expensive.

You have a dead spot. Sorry kid. If updating the OS still gives you the funk, you need a new screen.

not a solution, as I did it already twice, after a week or two you need to do the same. Probably the only option is to change the motherboard.

It was suddenly power off and didn't want to turn on. I put it on charger (before failure battery was around 70%), but it didn't power on and notification light for charging was very dim and blinking. Then i check my domestic forum and got solution from one user who had same problem.

How did you change the chip? I saw a video on Youtube that describes the procedure of changing a chip, and looks like it is definitely nothing for laymen.

Touchesceen isnt working anymore

Hi there,
so for a few weeks now my touchscreen hasn't been working anymore.
Power and Volume buttons are working fine.
At first i shut my screen off again and again until i the touchscreen responded.
But since today I couldn't get my touchscreen to work.
The touchscreen also doesn't respond in TWRP Recovery.
So does this mean that my touchscreen is defect?
It never fell down the glass is not broken. The problem occurred suddenly.
I am rooted and my bootloader is also unlocked.
I am on Resurrection Remix 5.8.0 N.
Fresh Rom installs didn't help sadly.
For now I am using my phone with a mouse via USB OTG..
I hope that someone can help me out.
Thanks in advance.
