Question about Hitachi Televison & Video
This is the proverbial "kiss of death" for a Hitachi set.
The protection circuit is shutting the set down. The reason it comes back on after few weeks or so is because the protection circuit resets itself after a while but detects the same fault when it is ON for a few weeks.
It is the protection circuit that is causing the set to shut down. Unfortuately we don't know which of the many sections of the tv is the one causing the problem in the first place.
Since it comes on for a few seconds before shutting down it may be assumed to be a circuit that builds up slowly after the main power has come on. That would be the high voltages. Since the picture is off color that also indicates a power supply problem. So, I am going to predict the main power supply as the source of the difficutien this set.
I don't think this is a home repair unless you are skilled in electronic circuits and have at least an VOM to do some checks and measurements.
Let me know if you have a voltmeter and know how to use it.
