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.
