      Fractionally better but still not in the right section!
      Check again the lvds cable that goes from ?????? board to the panel.
      I cant say which board as you have posted no pictures and not even told us
      the make or model of the monitor.
      Pictures please - one of the back showing the general layout and one of each board.

          well,I know about what cable are you talking about.I have spent almost 2 hours of trying cable positions.Its not about cable...Well there is connection on the power board which says +5v output.I took my voltmeter and I saw that voltage is chaninging from 4.9 to 5.13 very fast.It has to be constant or?

                      What kind of monitor is it and do you have a schematic.

                          White screen repairs
                          by harp
                          To ask here... I have few devices with white screen problem, actualy nokia 2220 and some fuji? camera, and try to understand what is common problem to cause that issue.
                          Yes, both devices work everything else probably ok, I mean, I hear intro melody and keypress click sound, DTMF tone, power on off... all ok.
                          On desk is nokia 2220 slide, and I check all screen connectors and components arround it, measure voltage drop, but all looks ok. I suspect on slide flex cable, but it look ok and white screen is not interupt while flexing board, pushing conectors, and sliding up down. In attachment...

                          Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
                          by Ryan.man
                          Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

                          My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

                          This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

                          by momaka
                          Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                          Having this very weird issue.
                          The owner of this laptop complained about screen being intermittent when opening and closing, and has been using the laptop on a thunderbolt video connection since the screen failed.

                          I swapped with a working screen from an A2141 waiting for parts.

                          The Os exhibits this weird behavior where it boots to to 1/3 the status bar, then it makes the boop sound. It's at the log in but for whatever reason the desktop isn't loaded.

                          The laptop boots fine into recovery mode. I updated from Monterey to Sonoma and the laptop still has...

                          Sharp LC-65Q620U White Screen

                          Another TV topic!!
                          I got this sharp TV that when I first plugged it in it showed the sharp logo and then went to the input screen. This was about 30 seconds and then it showed white screen. Now I can't see anything but white screen. This has a separate TCON and Main.

                          The TCON is getting 12V and several parts are as well but the VGH line is only .5Volts which I thought is totally incorrect.

                          Am I on the correct assumption that the TCON is bad somehow if I'm only getting that voltage or is there something else I should check?...
