[Q] No backlight on lcd - HTC Desire 610

Hello,
I am facing the problem with my htc desire 610. After booting my lcd goes darker and darker till no backlight there. I looked through all the internet and couldn't find any solution for that. It is not software issue, cause I flashed other roms, incuding stock. It's not lcd issue, cause I've tried replacing my mainboard with the good one and on the other mainboard it worked properly. I guess it is the problem with backlight ways on mainboard. Can anybody help me which part should i check or replace? Or anyone has the manual/scheme for this model's mainboard?
Thanks in advance.

Hermes black lcd

Hi, i received HTC TYTN from customer. On startup lcd will display, then suddenly goes black. Phone starts completely. I upgraded rom, but still the same. On boot mode lcd allso display. Only goes black on startup. Is this a
hardware or software problem?
Thanks
Try a a HR and see what happens or try to downgrade to another rom. If problem persists it may be hardware but if it is displaying on startup it sounds more likely software. If you have other software installed you may need to eliminate problem by installing one by one until you find the problem app.

S3 Screen Upside down after replacement - Help!

Hi Guys,
After replacing the lcd and digitizer on my S3, the display is appearing upside down?
The touch screen works as if it is the right way round, but the lcd is displaying as if it is upside down.
I've also tried another lcd/digitizer and got the same results!
Is there any way to solve this? Even if it involves using ADB or the likes?
Any help is much appreciated!
Thanks
software has nothing to do with this ( i believe ) ,you connected the display wrong .
Are you sure you bought the original display ?

[Q] Xperia Z Ultra Screen Problem

Hi all,
A couple of months ago, some sort of a ghost image started to appear on at the bottom of the screen (I don't know if it's a hardware defect or a software related issue)!
However, few days ago that ghost image started to occupy a much larger screen real-estate, which is quit annoying especially if you are using the device in landscape mode!
I've already restored my device, refleshed but it didn't help!
So my guessing is it's a hardware problem (please refer to the images below)!
Could anyone please advice on this?
I would guess part of the ribbon for the LCD has come off

If so, does this require replacing the screen?? or is there any other way to fix it?

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.

Problem after replacing touchpanel / digitizer. Need support.

Dear users of XDA Developers.
I have a problem after replacing broken digitizer in Evo 3D. Now I'm not sure if I damaged new digitizer or there is necessary to do calibration.
Maybe someone can help me to indentify what is the problem. Please see attached image with screen test performed. It looks like 1/5 from above of screen is not responding.
There is any way to do calibration?

Nobody knows hot to fix my problem?
