    Insignia NS-50L260A13 LCD TV white screen

    I have this Insignia that I picked up, not sure of its history or anything. When you power it on, it turns on, back light comes on but the screen is white. If you press the menu button or even otherwise, there appear vertical lines that seems to shift left or right sporadically. I opened it up, the boards all look good. Also measured the voltage on the Tcon board, it reads 11.9V and several small regulators on the main board read voltages like 3.3, 2.5, 1.8 etc. Any one have any guesses as to what is the problem here?

          You read the voltage WHERE on the tcon ? Check both sides of the fuse for 12v

              T-CON Bd has a fault. It could be the Von voltage missing or low or it could very well be the T-CON Fuse open.

                  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

                  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?...
