Question about Toshiba TN50X81 50" Rear Projection Television
A power regulator or a sweep power supply problem. The power regulators in the main power supply, and will have or start with STR###-## The # are numbers or letters. This is a repair that should be done by an amature or layman. This is a solid state set, and there are no user replaceable parts inside these sets. Have it looked at by a trained tech.
From your description, I suspect you have a power supply problem. It sounds like set is turning off because the power supply is not regulating properly. I would suspect you have a few Capacitors in the regulator circuit failing.
If you were to take this set into a shop for repair, I would expect the cost to be around $150.00 to fix it.
If you are going to look at it yourself. I would look for bad caps in the regulator section
If you are going to work on this yourself, I would recommend finding someone with television repair experience and the proper test equipment to help you. Television picture tubes contain, High voltage. You can be shocked even it the set is unplugged If the tube is not properly discharged.
hope u will b helpfull
