PANASONIC PT-47WX49 Convergence Chip
STK392-110 Replacement Instructions
Panasonic PT-47WX49 Rear Projection TV SANYO STK392-110 Convergence Chip
The STK392-110 Convergence chips used on the Panasonic PT-47WX49 and other brands of rear projection TVs have often failed within 6 years of use. The TV becomes a useless piece of furniture! My TV failed but I decided not to throw it away. I thought, "if I totally screw the TV up, what have I lost? It's already broken." I made the repair and you can too. But you probably have a few questions...
Do you know how to take the TV apart to identify the convergence chips and supporting resistors?
Where do you buy original equipment replacement chips that won't fail again in a few years?
What tools do you need?
Do you need special solder?
What is heat sink grease?
How do you remove the old convergence chips and solder new ones in place?
How do you readjust the convergence once the repair is made?
Is there anything you can do to prevent the failure again?
Have you ever tried to locate a Service Manual for this TV?
How much is this going to cost?
