    Hi Guys,

    I have a TV based on chassis gt8821.
    When I switch power on, the relay RLY901 toggles on / off continously and
    the led in front panel is blinking. But noting else, no image and no sound.

    Someone has an idea?

    Thanks a lot

    Yes, jam a matchstick in the relay. This works every time.

    I think you have an Onwa chassis. No 2SC2335 there but a relay instead.
    The power supply however was unchanged, so probably overvoltage
    condition caused by small electrolytics, also the HOT may be blown.

    probably kicking back off due to excessive voltage or something to prevent
    to much xrays, you may get it to come on by forcing relay closed but you
    may zap a few parts also, check flyback and pink wire to tube for signs of
    arcing. if all else fails just examin all to see if something has become
    toast, if you are going to force relay on, i hook a lamp in a series with
    it to take some of the current away from it, if bulb lights fully when tv
    turned on , then u probly have a voltage regulator short, other wise if
    the tv tries to power on and the bulb glows dimly you can try to hard wire
    the relay, but disabling protective devices on a set is never a good idea
