    Sony KDE-50XS955 12 green flashes blank screen.

    Ok so i got this sony 50in and when i plug it in I get 12 grn flashes and the screen does not come on. I pulled off the back and started testing voltages starting with the g1 board, now the top right plug is labeled PFC out (380v) when testing the voltage i get 321.1 volts and the other pin labeled PRI-VCC1 (120v) tested i get 39v to 41v. That indicates this board is not working right? well what can i do to get this thing working besides buy a new board? Any help would be apreciated.

      Also there is a fluctuating buzzing sound from (i guess) its a flyback transformer, if that helps any.

              LCD TV Green/Pink screen problem
              by jimjoe123
              I have a Dick Smith 37" LCD TV, Model GE6804. I am using it as PC extended monitor only.

              Problem is while watching tv, I hear a semi loud click(like a electrical breaker tripping due to overload, just sound like it but no actual electrical overload), then screen is covered with green or pink. I can still see the original picture image but overlayed by green or pink. See attached images. Pink.jpg is what I see, and Normal.jpg is before green or pink screen, What I captured was pink screen, but about 80% of time it's green and 20% of time it's pink.

              Then each time...

              by kokos
              Hi ! to all fellows out there!

              I have an LG 55inch 55RG910V-ZB Curved TV. With the following problem: When I turn it ON with Remote I get a Green noise Screen (attached foto).
              I have tried reseating all ribons, Checked PSU 24V,12V,3v ,etc voltages.

              The TV opens on the first Green noise screen and it freezes there -no respone of menu keys ,etc -only on/off via Remote. (I also noticed carefully that except from green noise screen there is a ghost image at bottom and left vertical side)
              I tried connected the lan and I can seee TV via local lan (as a device I...

              Sony KDL-55EX500 solid green screen
              by Nopy
              I have a Sony KDL-55EX500 which shows a solid green screen and I haven't been able to diagnose the problem. I was able to find a repair manual online and read a few forums on tv repair which pointed me towards it possibly being an issue with the power board or T-con board. Bad electrolytic capacitors seemed to be a common theme so I tried replacing all of the ones on on the power board, but that didn't fix it.

              My next step was disconnecting all of the cables and reconnecting them. That helped a bit, showing a normal screen most of the time, but still switches back to solid green...

              Samsung UN55J6200AFXZA Splash Screen Comes up, goes out, screen flashes one time and won't turn off
              by JunkmanJimbo
              Samsung UN55J6200AFXZA Splash Screen Comes up, goes out, screen flashes one time and then tv won't turn off.
              No picture. No sound that I can tell. Backlights are on and have been checked. Flashlight test no image on screen. I replaced the Eprom chip hoping that was the problem but nothing changed.
              Please help. Thanks in advance!

              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...
