    Toshiba 46XF355DB

    Hi guys,

    Hoping for a little assistance with this LCD TV if possible.

    Symptoms are from cold start - sound is fine, backlight lit but no display.

    After approx 10mins warmup, a power off and power on restores picture. (Looks like a MCU reset issue maybe?)

    If the set is powered up from cold and left on indefinitely the picture never appears - only a power off/on restores the picture.

    Any ideas??

    Cheers,

    Matt

      Heat issue? maybe the board like being warmed up before they start to function? maybe try slightly warming everything and see if it "cold starts" then? see if it is a specific board or area that has to be warm before it comes on?
