    Likely t-con, it's rare for repeating vertical lines to be caused by a panel failure.

      Ok,
      I had it in with a failed as15 chip
      replaced chip twice and both times have had this ...

      Posibbly bad batch of as15's

      or has something else also gone on the tcon board

      Good thing i didnt strip for parts yesterday..lol

        So a replacement chip solved the problem?
        Willing to help but I'm no expert.

          No,

          I had it with a faded screen
          replaced the as15 twice
          but this proble with the lines persists...

            You've tried cleaning and reseating cables?
            I assume no responsibility for any stupid suggestions I might post.

              AS15 wouldn't cause this. Doubt dirty cables would either. Likely a processor fault on the T-con -- maybe the RAM or BGA soldering. I think the M86 has an advanced T-con -- I can't remember if this model has the 100Hz interpolation stuff.

                Gone into storage till a tcon comes up at a reasonable price.
                might try relfowing the board if I get time..
                but otherwise will update once i have access to a replacement tcon.
                Thanks for all the input
