[Q] Xperia S no backlight - Sony Xperia S, Acro S, Ion

Yesterday I switched the battery on my Xperia S and after i assembled everything back the device powered up and the touch was working but i couldn't see anything. The screen doesn't display anything but the device is fully functional.
Can anybody here please help me with my problem? maybe i should turn up the brightness but i can't navigate there (because i can't really work when i don't see a thing). I have also tried restoring my device using the official Sony tool (Emma) but it didn't help me with the problem.

Take it to a repair shop, you may touched by mistake the screen leds.

[URGENT] Is my Play Dead? How do I fix it?

I've been having a problem with my xperia play screen over the last few days. Some times when I press the power button or the home key the screen stays black.
Today though I've rarely been able to get my phone screen on
I've got to the point now that my screen won't even come on. Even after flashing my phone again with a new firmware. Then when I tried to turn on my play the LED flashed 3 times but RED :O
I'm now charging it but when charging, the LED is permanently red.
Is my Play dead or is it something simple like my battery dying?

I just skimmed your post but is this problem linked to this problem at the main sony site...

If it is it maybe a software glitch which harmed your phone/device...

Sorry I'm new to this XDA Forum
Hey its me, the same guy from the official sony post,
I tried flashing new firmware, but that didn't work. so i ended up relocking my bootloader and trying an official update service, but that didn't work. I had to send it off to the sony repair centre.
one week later I got my phone back: fully working. they reprogrammed the phone with stock .42 FW
so send it off to the repair centre!
one note though. i flashed official .62 fw and installed doomkernel, but the next morning the screen went off whenever i tried to open settings. after 3 times it didn't com on again. after leaving the phone alone for 20 mins the screen would turn on again (after rebooting) but i'm sending it off to the repair centre again.
too bad the phone isn't fixed, still...
-this problem ( black screen or delay to turn the screen on ) is happening on some custom roms , which rom do you use ?
- sometimes when you change the cpu governor it happens , for example when you set the "powersave" profile for screen off , or when you use interactivex on your CPU .
i'm sure that related to your rom , your phone is alive mate
or according to 3raserNL information
- another way is : just flash a ftf .54 , .62 ...
good luck

[Q] HELP! Acro S blank display

Got a acro S 2 months back.. last week the screen went suddenly went BLANK. No display at all, only backlight.
Tried various method and updated using Sony PC companion to latest firmware.
I can turn on the phone. I can go into bootloader and go into flash mode. But screen is blank. When I plug in the usb to my PC, I can access the directory in the phone.
What can I do now?? Help me....
Have you tried hard reset yet??
Hold the Power button and Volume up button for few seconds. First you will feel one vibration then after a while 3 more vibration.
Then power on the device again.
If this doesn't help, then may be it could be a hardware issue.
Tried the hard reset. I even dismantled the whole phone to unplug the battery and check for any loose connection and water ingression...
I am suspecting it is hardware issue too
Anyone knows where to get cheap replacement screen?
Thank you.
Then it seems that it's a hardware fault. You may check here.

Or something may available in Ebay too.

[Q]Xperia Pro - Screen Issues

Hey guys,
My Xperia Pro has been running into some problems with the display as of late. What happens is after a short period of keeping the phone idle, it doesn't wake up. When the power button or the home button is pressed, it just shows a blueish-black screen and the lights between the physical buttons light up. Same thing happens when the keyboard is slid out. The backlight of the keys work but the screen still shows a blueish-black color. After trying again and again, the screen finally works, just to run into the same problem after locking the screen.
I tried changing the ROM and flashing a different kernel to no use. Then I finally flashed a stock Gingerbread firmware. Now the screen doesn't show any blueish-black shade or anything else at all!!!! I have currently just left my phone to charge because I don't want the battery to run out during this crisis. I have also re-booted many, many times by pulling out and re-inserting the battery.
Any suggestions and tips would be highly appreciated! Thanks in advance guys!
My Xperia Pro have the same issue . Like when unlock , no screen (black) ,
The issue I found out is having something to do with my back cover
ie. If I remove the cover and reboot , and then unlock /lock , no problem, As soon as i put the back cover , it unlocks with black screen , I was sure no kernel or fw was the reason , as i have been through diff kernels and fws /roms without an issue like this , and as soon as the black screen shows and you try to restart it wont even show the logo , so i was damn sure ,its no kernel issue , Please check this method , i will try to find the exact issue why the back cover is making this.
Update: Found out that the push made by back cover with the battery (which basically may be jamming the strip or something inside) is making the problem , It may have more to it than this ,anyway this is my phone's problem

That actually worked for me initially..removing the back cover and rebooting. But its not now, what ever I do I only see the dim lit LCD screen.
But yeah, I am able to unlock the phone in the blind and also hear the increase/ decrease in the volume by pressing the volume rocker and also touch and hold on the home screen to feel the vibration (guess for removing the widget or something that's already there).
So is there any solution for this, or any first aid before I get my Xperia Pro to the service centre ??

[PRO][TROUBLE] LEDs don't work.

Today all LEDs in my device stoped work without any visible reason. (notification LED, keyboard LED, nav-keys LED)
Super wipe and different ROMs (stock with flashtool too) dont help. I think it hardware issue. Maybe somebody encountered such problem.
thanks
i think you might have a hardware problem, if you already tried with other romĀ“s and nothing happen you need to repair the phone
Hey, i had the old xperia x10 mini pro, wich also had the slide out keybord. On that phone not working notification led ment that the ribbon connecting the screen to the phone was damaged, a week after the notification light stopped working my phone broke. I dont know if its the same issue but if it is from now on slide your keyboard out very gently, try avoidng it as much as possible

Touchscreen not working after locking the phone

Hey Guys!
I have a big problem!
2 Weeks ago, the display of my G3 (not rooted, original LG Android) broke and i sent it to repairmyphone.de (I'm from Germany) for repair. Today my G3 came back and the display was fine. So i think they changed the display and repaired my phone.
Sounds good right? Well not exactly, because now there is a problem:
The touchscreen is working fine, but when i lock my phone (With the DoubleKnock or the Button) and turn the display on again, the touchscreen isn't working and i can't unlock the phone.
Only after i pull the battery out and start the phone again, the touchscreen is working fine. But when i lock the phone the same thing happens again. Even when i turn off the lockscreen and turn the display, the touchscreen is not working.
The strange thing is, the KnockOn is recognized so it turns the display on when i double tap it, but nothing is recognized after that.
I did a factory reset but the same problem happens again.
So i don't really know if it's a hardware or software problem is and if any one of you can help me with my problem.
I wrote the repairservice an e-mail but i think it will be read on monday.
So if nothing works i have to send it back again, but maybe you guys have a solution for me.
Thanks in advance!
