My phone lcd and digitizer seem to work with no problems, but the backlight for the lcd got some problems, It won´t turn on when i press the power button. Sometimes it turns on by pressing hard on the left side of the sreen and edge or it will stay on till the phone locks. Its very weird.
I will possibly upload a video if i find a camera.I already opened the phone a bit but the flex cables seemed ok. Does anone has an idea?
Ps: My left thumb hurts .

Ok... I apolagize in advance if this has been muted before, but I really dont know what to search for.
My problem is, that when i make a call the screen turns off, ( As it should ) but when Im asked to tap in an extention number or 'press 1' etc I cant turn the screen back on, all the soft keys light up but the screen refuses to come back on untill I end the call.
If I dial in the number and the screen goes blank on connection, some times im able to turn on the screen if I move quickly enough and press the sta key.
Im running a htc hd2 with an the latest energy rom.
ditto
have the same problem, would love to find a solution...
Same problem here so I D/Ld Phonex from Iconsoft. Really like this a lot better and is so much more user friendly.
I'm not sure if you're having the same problem I was, but it sounds very similar...
What I discovered is that at the upper left of my screen protector, there are two round cutouts for the proximity sensor. The screen protector has never adhered very well at this point, and it was pulled away from the glass, causing the phone to belive that it was constantly near a face, and blacking out the screen.
I discovered this after being so frustrated that I removed the screen protector, and *voila!* the telephone worked as advertised. I used a hair dryer to warm the screen protector to re-adhere it, and the phone still works properly, but I don't know for how long.
I understand that there is a registry setting to disable the proximity function for the phone, but I haven't gone to this length.
I hope this helped!
I had the same problem till i change te Radio version to 2.10 or above then it disappeared
I have the same problem, screen protector causes this problem for me....
Hello! So my Xperia Mini pro has been broken, it doesn't show any image anymore, I think there is a problem with the screen but I want a confirmation or recommendation to find out what the problem is.
First the screen "touch" capability stopped working, and then two weeks after that, the back and option buttons stopped working too. And a week after that ,there was like a screen "flickering" (I tried to recreate the problem in the attached image) when I tried to either open or close the slider.
Finally the screen stopped working anymore. I tried to connect the phone to the PC but says that windows cannot recognize the hardware. And there's one more thing: I can turn on the phone, it vibrates, but the keyboard lights seems that are not working, they are permanently off.. and when I try to Increase the volume it doesn't sound either... There is only the black screen and a backlight.
Please Help me to find out what is the problem, I'm thinking to buy a screen replacement on eBay, but some people told me that is the "flex" cable. I'm not sure if there is a fix for my phone's problem.
Thanks!
Hey there.
Based on my experience, yes, your problem is most likey a flex ribbon issue. Your flex has been ripping apart lately, causing many of its wires to break. This can cause a lot of unpredictable problems, such as a misbeheaving notification LED, inactive ambient light sensor, or "dead" display/touch digitizer. Your problems have gotten worse over time, which is clearly a symptom of a broken flex.
You phone is no longer booting up to android because the kernel no longer detects a proper "response" from the display driver and halts the bootup. This is why you can feel the phone vibrating when pressing the power button, but nothing else happens. Your screen assembly is fine, I can assure you that, unless your glass is broken, of course.
Here's one hell of a good teardown guide: http://www.ifixit.com/Teardown/Sony+Ericsson+Xperia+Mini+Pro+SK17i+Teardown/7275
I used that very same guide when I repaired my own xmp. I regret messing with my screen assembly because I destroyed it and had to buy a new one, which is costly
Thank You so much for the advice ! Now I'll try to repair it, It doesn't seem too difficult. Thank You Again!!!
Xperia Ray user:
I think my ray has sporadic display coma issues.
it seems to happen when phone comes out of deep sleep (standby for a minute or longer) and i press home or power button to play with it. The backlight lits up, but the GPU doesn't seem to come out of its sleep (=coma?) and screen stays black with backlight on. The phone is then fully functional, also touchscreen works well....but without display output.
Only way to wake the screen up is to press the power button repeatedly (press twice fast (=off/on)...nothing..wait a second press twice fast...repeat until screen is on)
I tried "every rom/kernel" out here (incl. factory resets), no simm, no sdcard etc. , also added wakelocks to keep the device out of deep sleep..and the only thing which works best for me is to use cyanogenmod 7.2 (GB). It smells like a hardware problem on the qualcomm chip with its embedded GPU.
Somehow cyanogenmod has a different approach on switching on the screen?
Still when making phonecalls with CM 7.2 and screen goes off by proximity sensor...the coma issue comes back (black screen) and i cannot put the call on hook as i dont see anything on screen.
If anybody knows a low-level tweak (deeper than kernel goes), please PM me and write a reply.
Sorry... i refuse to accept that out of nothing this screen coma issue pops up...and when i finally have the display on...everything works fine.
Thanks in advance

My 2 friends have xperia ray and both of them are facing the same issue, this issue started to show up after disassembling the phone
for changing the housing.
Did you disassembled your phone or gave it for reapir where they disassembled it?
sometimes the touch screen also stops working but its happens rarely.
I don't think its an hardware problem because it only showed up after disassembling the phone, i think the housing or the touchscreen
cable becomes loose after disassembling because i kept some packing of paper over the touchscreen cable and its sometimes solves the problem but still happens!
I went to sony care they disassembled the phone and found nothing bad inside and told me it may be a software problem but ever since they
disassembled and reassembled the phone the issue magically disappeared!!!! but one of my friend is still facing the issue.
So its can be a loose screws or housing!
Hello!
My phone fell from a high place some weeks ago and the screen shattered. Touch was unresponsive, clicking everywehere, but LCD was fine, i could see everything on screen normally.
Ordered a new screen. Changed it, but when I turned it on, only backlight of the LCD was visible, but it was displaying nothing. I thought it was a defective screen (either way, it was, lots of stuck pixels), sent it back and bought another from the same seller. When I changed it and turned it on, again, no video output, lcd would light on but woundn't display nothing on screen. Googled a bit, found out it could be a defective fuse on the motherboard, and that soldering it again would solve. I know nothing about this kind of stuff, so I picked up a tweezers and apllied a little force on every fuse, because I thougth that way I could try to solve it. Well, it worked, kinda. I put the screen above that blue plastic glue only for testing, and it worked, I felt reliefed for seeing sony boot logo again. Figuring out it had worked, i took out the screen, took out the blue plastic, and glued the screen back on. For my surprise, it had the same problem as before, and it doesn't matter what I do now, it wont work anymore, only displays a black backlight with no video.
Could anyone help me out with this? Give me a hint of why it worked once but not anymore. Could it be there's really a defective fuse, or it was just a coincidence that it worked after it had force apllied? Also, the Screen flex is kinda loose, it keeps coming off all the time, and it's really hard to plug it to the LCD sometimes, is it supposed to be like that, or could it be the culprit? Also, touch is working normally, i can't see nothing on screen but i can click and feel it vibrating.
It's kind of a big text, but that's the way I could explain it. Sorry for the bad english, it's not my native language.
And thanks in advance if anyone can help!
Hello, last week I had to replace my phone's digitizer. I bought one that included its frame to make sure I don't break the flex cable, I hooked up everything and I'm sure as hell there's nothing wrong. Randomly when Im going to unlock the screen doesn't respond, also noticed that when it happens the menu button is always "pressed" even if you don't touch the display, is there a way to fix it, my brother has a redmi 3 too and after he replaced screen same things happen. He has lineage OS and he can reboot because screen doesn' turn unresponsive
