    Toshiba 32av500u bottom 2/3's of screen black

    I have a 32" Toshiba 32av500u that has an obvious display issue. The top third of the screen is normal and displays picture and menus normally while the bottom is black. If I have no input set and just pull up the menu, as the menu sits on the screen color tends to "bleed" down through the bottom of the screen.

    I acquired a used tcon board and swapped it out only to get a series of awful vertical lines and distorted menu. Putting my original tcon board back in and got back to the top third of the screen works but the bottom is black.

    Anyone have this problem in the past? Bad TCON, main board or screen?

    We've got a 37av500u and I am almost positive they share the same tcon board. If I have time, I'll pull that board and swap them thus eliminating one piece of the puzzle.

    This would unfortunately be an LCD panel issue.

        Whats your thoughts on the vertical lines in general? I have a vizio that is full screen of rainbow vertical lines and a philips that is half screen of black or vertical lines and the other side is solarized?

          Vizio full screen can be a T-con failure but is most likely panel.
          Philips is definitely panel.
          (Assuming both are LCDs)

            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 TCon test pins for screen test
            by alltvrepairs
            Hi,
            i have a 65 Panasonic TX-65HX710E using vestel 17MB170 main and Lg tcon.

            Few drops of water fell probably near COF and have no display. Tried removing tabs but no.part of display present as if tcon fuse open. However 12v is present and tcon can be felt warm enough that supplies are present. Backlight and sound ok.

            Anyone knows if this TCon 6870c-0805A has any special test pins for rgb test?

            Appreciate your help....

            Hitachi 58HK6100U - Horizontal Lines (Bottom third of the screen)
            by kdaniel
            As stated by the person I collected the TV from, it just stopped working overnight. However, I still gave it a go to try and repair it.

            There is a thread on the same TV but with slightly different issues where they had to tape connection points on the ribbon cable, so I want to see if this is repairable by any chance.

            After bringing it home and plugging it in, the TV turned on with its backlight working but had no picture. After removing the back cover, the first thing I tried is to unplug one of the ribbon cables and the situation is as follows.
