I wanted to run my cracked screen phone as an emergency phone, so I purchased the whole front and this is the situation:
VIDEO
Every time I start the phone with the old display and then while it's working I replace it with a new one, it works fine until I restart it. Conversely, it works the same, every time I start the phone with a new display, the halves of the screen are swapped until I restart the phone with the old display.
hello. looks like the controller ic is broken.

The digitizer on my HTC One X+ seems to be unresponsive on some strips of the screen.
This problem occurred after I replaced the lcd+digitizer module because the original one was cracked.
First 1 strip of the digitizer didn't work but 1 week later there were 3 unresponsive strips.
Today I reopened the phone to check if the new screen was the problem but after putting the old cracked screen back, it showed the same unresponsiveness but on different strips. I added a screenshot of a draw test in the attachment (since I can't post images from outside links).
On this screenshot, all 5 strips of the bottom half of the screen are unresponsive but sometimes only 2 or 3 strips don't work.
I notice that the screen freezes sometimes while trying to unlock the phone (which is a pain currently). Also the phone gets really slow and sometimes it randomly registers touch all over screen while I don't even hold it.
So my question: Is this a hardware or software problem? and does anyone have an idea how to fix this?
On the side, another problem: when I try to update the phone's firmware I get a notification that a new update is available (this is a very old update from months ago) but when I try to update it, the phone reboots, tries to install the software and then a red question mark appears on the screen. I haven't been able to update the phone for about 4 months now. Don't know if that has anything to do with my current problem but I thought maybe I should mention it.
Thanks in advance.
This may be because of the bad connection between mainboard and the touch module.
If you can , pull apart your phone and check the cable that connects the digitizer. Also, clean out cable's jack and cable's fingers.
As i am new, i cannot post imgs/ links.Search on youtube for "one x screen/ digitizer replacement" and follow step by step instructions.
My phone's LCD was broken, and I wanted to change it. I ordered a new LCD with assembly and connected phone to this one (changed old front with this one). First of them worked well, but was broken after one month, I was my fault. But it already works, touch works very good. In second and third one, after installing touch not worked. But I put it some minutes, then it started recognizing touches. Worked for more than a week, and yesterday night my phone turned off because of battery. Today I charged it, turned on and now touch not works again. When I press to screen hardly or press in somewhere from the back it recognizes touches. What can be problem? I searched about it but all results were about problems with broken glass, but my problem is different.
Thanks...
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!!!
hello, this it's the first time i write an entry in a forum, but i have a problem with my s2, the problem it's that i buyed sometime ago a screen replacement for my phone because i accidentally broke the lcd, and when it arrived, i changed it because i have some experience with this phone because i have already changed it's screen once, now, while changing the screen, i broked two things, the flex cable of the call speaker and the volume flex that goes onto the motherboard, but with that damaged, my phone turned on once, i didn't see that the volume flex wasn't there so i opened my phone again and now, it doesn't turn on, it's like only the leds of the screen turn on when i touch them, i don't know what to do, i have gone to a mobile center and the guy telled my that to repair that i have to change the flexs i broke, i have changed the call speaker but the volume one it's broken, i just want my phone back.
Sorry for my bad english
Hello XDA.
The screen on my LG G3 Verizon (vs985) has been acting weird and I really would like a second opinion about if I have a screen issue on my hands or if it is a motherboard problem. I included pictures below.
Screen responds to double-tap-to-wake, and buttons still work. I'm able to turn phone off by pressing power button (as long as it normally takes to display Power Menu), then tapping on where the Switch Off button ought to have been displayed. Apparently, motherboard sends stuff to screen, but screen unable to visibly display it.
I've been using motherboard since it was bought new 6 months ago so I really doubt it's the motherboard, but I could be wrong. Screen is over 4 years old. The best way would have been to try another trusted motherboard (if screen is still not normal, then it's DEFINITELY screen's fault). So in the absence of such a conclusive test, I would appreciate opinions.
Thanks.
Pictures (L-R): When booting (picture taken with flash), when booting (picture taken without flash), after booting into Android, phone charging with screen switched off.
SOLUTION: It turned out to be a screen problem (screen was replaced and voila!).
