Panasonic PT-53WX42 The red Convergence just all of a sudden went out of alignment when I changed the channel. The other colors are aligned but the red will not go back into alignment after all we tried. The red does move but not all the way back into alignment

Blue background lines with colors otherwise OK may be a loose or dirty blur drive potentiometer on small circuit board behind front grille and beneath front imerboard cover. These are hot-glued in place from factory but may be the cause f the problem. They're VERY sensitive.

If you have bowed blue lines instead of properly aligned colors, you probably have a blown convergence amplifier IC. These boards are no longer available so yours will have to be repaired. Some shops repair them but many send them out for 6-10 weeks. Fairly expensive too considering the amplifier chips are about $35 each (x2).

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

  • Screen is bowed or warped.

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!

Color guns out of alignment


It sounds to me like the convergence amps themselves have failed. Ic7001 and Ic7002, both are STK392-110 Sanyo built Ic's and not an expensive job for a qualified shop. When shopping around for a shop to repair it ask what they charge for replacement of the convergence amps in this unit. And take the unit to them to save pickup and delivery charges...
Have a great day!
