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!!!
Hi,
Trying to fix a Z2 for a friend. She dropped it, smashed the screen. You could still see the LCD, but the digitizer was fubar. Ordered a new screen assembly, but after the replacement only the LED backlights work - no LCD at all. To test, I reinstalled what was left of the old screen, and no LCD, just backlight, so I don't think it's the new screen. So then I ordered a new main ribbon cable and replaced it. Same result: no LCD, just backlight. You can hear the phone on when it's on, the phone "responds" when you touch the screen, you just can't see anything. I upgraded to the latest software update tonight using PC Companion, but no change.
So, the only thing left is the motherboard, right? I know there is a fuse on the motherboard that, when it fails, it kills the backlight and leaves you with only the LCD. I have the opposite problem. I'm hoping maybe there is something like that for the LCD??
Thanks in advance,
Heath
I have same issues with you and also try ten new lcd all show backlight only..what your solution??
Have you tried to connect it via a MHL cable to TV ?
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
Hi there - I am wondering if I can get some help here.
I had an old working HTC Evo 3D and I use it as a spare phone during travel to use prepaid SIM cards. I wanted to change the complete housing of Evo 3d and purchased a front, middle & back frame from online OEM vendors. As a newbie, I was so excited and started to disassemble the phone and to put into the new housing. All went well till I started to take the LCD and digitizer from the old housing. I made a mistake and ripped the flex cable of the digitizer. I felt very bad and then I decided that I need to order a new digitizer online.
I continued to reassemble the phone with the new housing till I receive my new digitizer. I made sure that I kept the sticky tape in the front housing intact so its easy to take it again. I completed the assembling and when I turned on the phone the LCD was displaying white and black dots like grains. However, I could hear the HTC boot sound the “Quietly Brilliant” sound. At this point, I thought I have damaged the LCD too.
Today, I tired to switch again, I dont see the phone booting-up or hear the boot-up sound or see the white and black grain screen. When I charge the phone, I see the red LED light and then after some time it turns green. I tried all type of resets like power+volume buttons, power+camera button, long press power button. However, I dont think anything is happening.
Now, I am worried if the problem is now with the display or I damaged the motherboard. Does anyone know if the phone wont start if there is a damage to the LCD/digitzer? I am just waiting to know what might be the problem before ordering LCD/digitizer. I am unable to check which part is damaged now.
Thanks in advance!
Hi everyone,
for the past few weeks I've been having this problem with my p20 lite (ANE L21): basically sound randomly stops coming out of the speaker, but what's strange is that if I press somewhere in the middle of phone's back side (let's say at about the center of the back cover) the speaker starts working again, and then randomly stops working until I press on the back again.
The back cover is actually cracked, it's been broken for several months but never had an issue, I don't know if it's related. The phone is out of warranty. Any idea what it could be? Maybe some faulty contacts?
maybe just speaker or flex broken? uncover and try gentle move flex from sound board to main board, if sound apear, mean flex broken or maybe just push it in socked
