    Phillips 50" plasma white in center of screen

    Phillips 50PF7220A - Ocassionally the tv will get a snowy white image down the center of picture. Last night worked great for 6 hours. I'm hoping it caps, haven't pulled the back off yet, Could see a green led in back. Bought a capacitance meter last week. Downloaded the Service Manual last night. Attachment has some reflection of window blinds.
    Any ideas?

          The led on the main logic control is the one flashing, both on power supply are on steady.

              The snow is actually a previous image (image retention? / ghosting), ex: you can see the Netflix screen well after you are watching a movie, or OTA you see a image from 10-20 seconds ago. Must be a defective board. It works great sometimes, though.

                  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...

                  Sharp LC-65Q620U White Screen
                  by EazyBone
                  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?...
