Question about Panasonic PT-47WX51 47" Rear Projection Television
The convergence IC most likly shorted, and burnt out the b+ feed resistor. There are two IC's inside this set to control the green red and blue convergence. They are most likly STK 392-###. The ### is another set of numbers that change depending on the model of the set. They each have three amps inside each one. You really should have both of the IC's replace with only original parts, as sub parts do not hold up and will not last as long as they should. Both IC's are soldered into place and if you decide to do this yourself, please be aware of the extemly high voltage inside of these puppys. there really are no user replaceable parts inside these sets unless you have solid state repair experience. Not only will yopu need the proper IC's, but you will have to find out what was burning. my best advice, Play it safe and call in a trained tech to assist you with this repair. The price should run someware between 300 to 450.00 to repair. Good Luck Please do not forget to rate this thread.

Techman,
Thank you for your prompt response and your helpful advice for my TV problem. I just spoke to a local repairman and he stated that these ICs would need to be changed every 5 to 6 years to maintain the unit's convergence. Does this sound reasonable from your experience? I appreciate your feedback. Thanks.
Thanks again Techman for your knowledge and info. A repairman came by yesterday and opened up the TV and took what looked like a circuit board back to the shop to change the ICs and a part he said that looked as though it was "fried". He will also reset the board back to Panasonic factory settings.
The initial problem was that the only colours seen were red and green. That was followed by no colour at all only black and white television. For some reason, when I watch a DVD or blue ray, full colour returns.
