    I have this unit that seem to have a problem with auto shutdown of the
    power supplyy.
    It goes Tick Tick Tick.
    I suspect that there is problem with the high voltage area of circuit
    or else a shorted power supply voltage outputs.

    I have taken the modules aparts, looked for cold joints/bad caps/open
    resistors but did not find anything yet.

    Has anyone encountered the same fault on a unit like this

    Thank you for your help

    I hate to see it go to landfill or recycler.

    I have checked a few more things.
    The DP06 LED is RED which around the Voltage regulator assy.
    The regulator is a STR6629B, Is it a common problem with these units?
    I will check the DC voltage in around it, but it is probably a case
    where until I get the Horizontal oscillation going, I am not going to
    get proper values anyway.
