    toshiba 40 inch lcd tv with lines and screen fickers

    hi...need your help

    toshiba 40 inch lcd tv..

    sold a main board on ebay from a tv with cracked screen....tv worked fine other than cracked screen...no other issues...

    the buyer says board no good....he said his tv still has lines across screen and flickers

    since i know my main board works i know his issue is not a main issue......well im pretty confident....nothing is ever 100%

    what do you think?.....all input would be appreciated...i get tired of buyers on ebay that buy wrong boards and then want refunds inclduing shipping back.....it sucks

    thanks

      You should ask for the screen shot of the image on the screen.
      People on EBAY use people like you and I for the board swapping troubleshooting, it is one reason we do not sell boards on EBAY any more, sick and tired of dealing with DIY that really do not know what they are doing.

        but from what i said.....could it be a main board?....i know my main worked so.....

        to me it sounds like bad lcd panel / connections

              If he has a couple solid Vertical or Horizontal bars, main board cannot be doing that.
              Flcikering: Bcklightights flcker, that can be due to bad dim command signal. Bad T-CON is causing the images flicker?

                      I just saw one TV repair company make short 1 minute youtube videos showing the board in a full TV working on video and they clearly mark the board with a marker. So presumably, if you are buying a working board, they link the youtube video with the unique marking.

                      That way, the buyer can't say they got a non working board?
