[Q] [HELP] Xperia Mini Pro Broken Screen - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

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!!!

[Q] Brick or hardware failure?

Hi guys,
I bought a second hand mini pro, and flashed (rooted, unlocked bootloader)it with the help of one of the several guides. with Simplexity and MiniCM7
It seemed to work fine at first, but now something odd happens.
I can only turn the device on (working) when I keep the keyboard slided out. When I start up with it slided in, The screen is turned on but no image appears: It stays black.
When it is turned on (slided out) I can use the phone normally. But when I slide it back in, the screen is frozen and won't react to touches.
Putting the phone in and out of standby (slided out) will have two possible outcomes: Either its usable as normal. Or it simply won't come out of standby at all. The phone seems to react (sounds) to pressing the buttons on the keyboard though.
I used Seus and manual methods to reflash to stock, try other kernels, but the problems remain.
I think it's the hardware that's failing but maybe this can be caused by the flashing as well?
Are there any methods to rule out one or the other?

I'm responding to the thread's title : It's a hardware failure.Brick means you can't even power it on/flash mode.If I helped click the "Thanks" button.Also,try using nAa-11 my and x10man's ROM called XMP Rom and tell us if you still have this problem.I understand that you posted this here (If you post it in questions section almost no one will respond )so I won't tell about that.
(Oh, my bad. Mods feel free to move my thread)
I was afraid of that. I'll try your ROM as well, but I'm afraid its the hardware too.
Thankfully I only paid 30 euros for it
I think the flex cable is gone bad, i have the same problem here. My mobile doesnt respond to any touches. First it happened only when i would slide the keyboard. But now its dead as a whole

The XMP rom didn't fix it, so I guess you're right. Would a flex cable (those are the flat orange ones right?) be expensive?

I hope you fix it
This is the cable we are having a problem with, i have given my mobile for replacing this stuff as i couldnt get this locally. This board houses the LCD and the digitizer and the buttons connect to this. The black cable goes to the motherboard. Its pretty simple to take apart the phone, but take care while doing so. Another thing its that, when you are opening the display panel, its better to use a guitar pick instead of a screwdriver and open it at the latches, that would avoid damage to the outer plastics.

[Q] Screen COMA issue (xperia Ray) adreno 205

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!

Blank screen, only backlight ON

Hello everyone.
I have a problem with my smartphone Sony Xperia Z2. I dropped it and the display broke. I bought a new display. When I connect he went crazy. He began to open the application, clicking like 10 fingers working on it simultaneously. Because I thought that the display is faulty, I've exchanged for a new one. But now even bigger problem. When I turn on him, he does not show anything on the screen except the backlight. Do you know what the problem is and whether anyone had a similar problem? So, when the smartphone turns on, lights up only the backlight but nothing on the screen showing a. At first, there is a lot of vertical lines on display, and once he just fade out, and from that moment display is blank only backlight working. I try to update software, but nothing change. Restarting, and turning off also nothing.
Please help me solve this, for me very frustrating problem.
anyone?

Did you ever get this resolved?
I had this issue after a screen replacement for a shattered screen. I was sure I had damaged something in the process (ribbon flex cable, motherboard, etc). Turns out the replacement screen was faulty. A new working screen solved the issue.

Xperia z3. Lcd Back light on but screen black.Help !!!

I have Xperia z3. When I turning on phone Lcd light on but screen blank. I can heat sound and so on. Digitizer when pressing is working as I hear nose. But screen still blank. | tried few screens but still same. What it can be????
Please help.....
This is the Z3v forum not the Z3 forum.
I would say a screen failure though.
Verizon has open enrollment right now so you can enroll in a insurance plan and get another phone, if yours is out of warranty.
Your Display is dead - Had the same problem.
Everything worked fine just my screen wouldn't show me anything. Ultimately I replaced the display by myself because I didn't have any warranty and now it's working again.
You could try to send it back to your vendor or order a new screen (70-100€) from ebay and replace it yourself.
Good luck!
Hello,
I guess I have the same problem:
I got a Z3 one year ago.
But spontaneously the screen just stayed black.
I can boot the phone, the backlight is working. I wait a little bit but the screen is still black.
BUT I can touch and select camera and take a photo. I know, because I can hear the sound of camera. I can open the dial pad and dial a number, I can hear the different sounds.
The phone is original, have never been opened, no other software.
I already tried with "Xperia Companion" to install latest updates and repair the phone. Nothing worked.

Did a screen replacement solved your problem?
A feedback how the problem was solved would be great because I don't wanna buy an expensive screen if anything else is broken in phone.

LCD Backlight is on but there's no video output

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!
