This is my second Cricket smartphone in 6 months and both have developed the same issue:
The screen glows with no visible image rather than displaying anything. The touchscreen still works while this is going on as I can answer phone calls. I found that by inserting the usb plug, with some light jiggling, the screen will sometimes briefly appear. To begin troubleshooting, I opened the phone and re-soldered the usb contacts. This was of no noticeable affect. I believe the problem lies with the ribbon that is seated right beside the usb port and seems to run under the screen. Can anyone tell me what the proper name of this is, whether it can be replaced, where to find a replacement, or give any suggestions as to a quick fix?

Hello gurus,
I have spent a few hours first looking around in the wiki for help. None found yet. Please diagnose and help me get my display working so it does not fade when I release finger pressure from the tmobile logo area. To operate the unit constant pressure need be applied to that spot for the display to bleed through. Otherwise it fades to white. Please advise. Thanks. G
I have the same problem, I have to keep it squeezed on the left hand side.. I read a thread about it before and everyone was saying that its a loose/crap connection for the screen..
It sounds like a loose connection in your upper slide. I would recommend finding locating the Wizard Service Manual and following it to dis-assemble your device and "tighten" up that loose connection.
KEEP IN MIND TAKING APART YOUR DEVICE WILL VOID YOUR WARRANTY
If you find that it is not a loose connection and that there may be a more serious issue, then I recommend sending your device back to HTC to have it repaired.

It's for sure a connector problem. This happened to me 3 months ago. I dropped the phone and it went white. so i dissembled the phone and the film connector that is used to connect the mainboard with the screen was loosen. i put the connector back in place and everything was ok.
Hey guys, my screen cracked and while the glass didn't smash it did get busted up and now there's a clear crack in the corner of the screen, so it doesn't turn on. It did at first but it was just lighting up green with Android in the background very distorted, now it doesn't at all.
Am I right in thinking a LCD+Digitizer part will solve this? I've tried phoning it and it works, I can talk on hands free and on the speaker after unplugging the headset, email alerts and such all work too. It's just the screen from what I can tell.
Just want to make sure other people think I'm right in assuming the phone will be fine with a new screen kit.
Thanks so much.
edit: I forgot to turn USB debugging on so I can't adb into it, but the on device and SD card storage work fine when connected to my PC, all signs say it's just the screen that needs replacing
try to guess which section questions go to
Mine too
When my GS3 drop down the screen went black eventualy, but it was possible to answer calls and do some things blindly . You have to chnage the creen i thing.
Be handy if you had a hdmi cable to test it.
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!!!
Due to damage done to the LCD of my S II I had to replace it. So I did that and I noticed two very serious issues. The first being the unresponsive touch buttons to the bottom right and left of the device. They were also not illuminated, there was also no evidence to suggest they were not connected correctly.
The second issues and by far the biggest is the unresponsiveness of the touch screen. When I enter my pin the first touch takes a few seconds to respond, then it proceeds to work as normal until the phone is unlocked. From that point whenever I try doing anything it behaves erratically. For example when I dial out it is painfully slow to respond to the inputs given to the touch screen.
Is there are way to address these issues and remedy them if so how could this be done.
Looks like a bad piece of hardware. Did you get the spare part from a trustworthy store? About the softkeys, you could check if the connector is connected correctly. As a workaround, you could use onscreen buttons.
Hi all,
Today I've replaced the screen of my Poco F1. Everything was goig fine until I started puting everything back together. When I had the new screen connected, I tested it by switching on the phone and entered the testcode *#*#64663#*#*. For some reason the code didn't open the function test menu (I'm running Pixel Experience, could this have something to do with it?). I didn't think much of it and since the screen seemed to be working properly, I switched off the phone and went ahead and started putting everything back together.
Before shoving the back cover back on, I wanted to test everything so I switched on the phone. After the initial "Pocophone - Unlocked" message, the phone shuts off. I am able to boot to TWRP and access internal memory and the SD Card. From that point I tried:
Taking it apart again to the point where I switched on the phone and it was working
Plugging the old screen in
Recovering from a month old image I had on the SD Card (now it goes straight into fastboot when i try to boot to system)
Wipe system, data, dalvik and cache and flashing clean Pixel OS
Sadly, none of this solved thie issue. At this point I've ran out of ideas so I'm hoping someone here can help me out.
I'm open to all sugestions and please let me know if I can test anything or if you require further information.
Thanks in advance!
How about trying to revert back to stock rom using fastboot mode
Turns out, it wasn't a software issue. I damaged the dock connector on the motherboard (where the main board flex cable connects to the MB). I removed the pins that were damaged (2,3,4,5 counting from the top right to the left) and somehow the phone now boots and seems to be working fine. It only doesn't indicate that it's charging, even though it is. Is there someone who can advise me on whether I can continue using the phone or if it's doomed to fail and worst case, explode (overcharging?) I'd also like to know if there's a better place to ask this question.

Your local Xiaomi Support Centre. I mean you have snapped some pins of a connector. The connector needs replacing.
