Question about Panasonic PT-56WX53 53" Rear Projection HDTV-Ready Television

2 Answers

Panasonic PT-53WX42 The convergence went out and when I tried to adjust it in the menu it would not adjust enough. The convergence seems to be off basically just the red after reading this forum it must be the convergence IC's that are bad. I need to know what parts I need? How much it would cost to fix it? And if I may be able to fix it myself? Thanks a lot I appreciate it.

Solution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com . They have put together convergence repair kits for most models.

The kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, etc. Everything you will need to do the repair yourself.

Aok1945,
This set uses two Sanyo Stk392-110 amps and six 2.2 ohm 1w resistors in the convergence. Parts are under $50.00 but the last part of your question is the tricky one, what skill levels do you have? On a scale of 1 to 10 and anything over a 5 being a skilled tech this repair would score an 8 because of the removal of the signal board to desolder the amps and applied heat stress on the 40 pin amps putting them in place.
If you need to locate a tech try http://www.tvrepairpros.com/ and ask a few for their estimate on how much to replace the above.
Good Luck!

Need to replace the convergence amps and any 2.2 ohm resistors in the return. That unit takes two STK392-110 Sanyo amps - but for greater reliability use STK392-150's and get them, from some place like ACME to be insured their not chineese knock-offs..
