    Toshiba 49L310U screen half white half black

    Hi all,
    I'm trying to repair my son's TV by following several Youtube videos. Original problem was no picture but there was an image if you shine a flashlight at an angle. There was audio but there were also no backlights. I replaced several LED strips and after reassembling the TV they worked. When I powered up the set there is a brief flash of light on the screen but no picture or image. Thinking I had incorrectly inserted the data ribbons from the T-con into the panel boards, I tried removing and replacing the two ribbons. Now when I power up I get a screen that is half white and half black (or dark). I've tried this a few times and end up with either no picture at all or the half screens.
    I would greatly appreciate anyone's input on what I might be dealing with at this point. I did replace the Power Supply board first before the LED strips so I'm in for a bit of money already.

    Thanks to everyone for any suggestions.

      Check for around 12 volts on each side of tcon fuse, negative probe ob metal/chassis back, positive probe on each side of fuse, to see if that section is still ok.

          TD Systems K50DLG12US half black and half white screen
          by Raulnn
          good night! I have this screen that looks half black and half white. the tcon gives a low vgh value (5-6v). the rest seem fine. I first removed the flex from one half of the panel and then the other. Removing the left, vgh increases it to 25-26v. I think the problem is in that area, but there are not many elements on the integrated controller board. there are no shorted capacitors. could they be a cof? Some help?

          By the way, now the entire screen is black. Maybe some flex was not connected correctly... I have exchanged the flex and there are no variations, I don't think they are the...

          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...

          Sharp LC-70UD1U Half screen Normal half screen is white
          by Megan0
          My Sharp LC-70UD1U Screen is black and flashing, "I attached the video"

          Well, I opened the back cover and as you can see in the picture, I unplugged 2 L (left) ribbon, TV turned ON, but half of screen (Right) is normal, and the other side (Left) is white. I continued to test...
          Result:
          I swapped the ribbons L<-->R = Blinking 2x power light, 5x timer light
          Unplugged 2 R Plug 2 L = Blinking 2x power light, 5x timer light
          Unplugged 2 L Plug 2 R = Blinking 2x power light, 5x timer light

          Only in the first test, where I did not          ...

          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...

          LG 55UH6150- trouble powering up, then half lit screen (pictures!)
          by valvashon
          The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
          Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it...
