PT-53WX42 IC replacement

you need new convergence chips, there are 2, part number stk 392-110, also you must check for burnt resistors, if you don't have very good soldering skills at least, you will need a tv repairman.

You should have a TV repairman look at your set to see if you have a bad tube in the set, It might just be a convergence ishue, if thats the case it might be worth fixing.

If you've already replaced the convergence IC's and confirmed the coolants in each tube are filled, you probably need a factory level convergence done.

The procedure is 18 pages long and requires a NTSC pattern generator to do correctly. You need a funtional remote. Personally I'd recommend finding a well-trained tech to do it for you. Takes
about 2 hours to do both 480 and 1080 modes. Anyone who tries to do it from home without equipment is asking for headaches. It's hard enough to do in our shop... (were factory service for Matsushita)

You might get away with a minor touch-up for any particular area, but going into the factory-level setup mode without knowing what you're doing is not recommended - you may find yourself replacing the EEPROM.

Good luck, Mark

what happens if you adjust the contrast or brightness?

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

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.

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.

Change both STK convergence IC's for reliability. They amplify/control both horiz and vertical. re-align after replacement.Locate them on the largest heat sink in your set!

if you can remove the rear panel assy. look for the convergence ic's they start with stk--- and you got the part number you need a source panasonic is 814 source and the number on the ic's stk 390 ----/
