    LG 32LX1D half screen bad picture

    Ok guys what its doing is the right half of screen is green lines, also last time powered on was not showing the video , but had sound, then it would flicker the video, warmed the main board with heat gun on caps (the 4 470 16v smts at the top left on the main board) flicking stoped video stayed but still half video all washed out?

    power lines all look good.
    Thanks
    Mike

    Re: LG 32LX1D half screen bad picture

    I have seen this problem before, the one I fixed was due to loose/dirty connection on the LVDS cable, this cable is attached to the T-CON board on the LCD panel assembly.
    I see the end of this cable attached to the main board top center, but to get to the other end will require a lot of disassembly! You may as well reseat the cable between the t-con and the LCD panel at the same time.

      From what you have tried it would suggest cap replacement would help. However the
      picture of the board is too blurred when enlarged. Can you do a picture of each board
      clear enough for us to see the component descriptions.
      In heating the caps you may have also heated other components which have affected the output voltages. What make /series are the caps.
      Please can you update your profile with the country.
      Please upload pictures using attachment function when ask for help on the repair

          HP Pavilion 15 bc400ns - Complete Black Screen - Only video on live usb
          by iZakre
          Hello everybody!

          To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.

          The thing is that I had installed TeamViewer and could log into the computer...

          Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
          by Mgiffune
          I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

          I ordered a supposedly ‘new' Tcon board this time, and

          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...

          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...
