Question about Panasonic PT-56WX53 53" Rear Projection HDTV-Ready Television
Your TV most likely has a Convergence Chip Failure ( common problem )
Here are some of the most common symptoms and example photos of a convergence problem
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.

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.

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..
