Replace the pcb convergence board,, It costs $96 and takes 10 minutes to replace you will have to manually line up your convergence afterward as the settings go to factory default. Everyone that owns this set has or will have to replace this part within 3 years

This happened a few years ago to me. I called the repairman out and he said that I had my tv too close to a magnet source, which turned out to be a speaker and also the reciever for my home theater. See if this may be your problem. Good Luck.

Red Ghost and bowing

The STKs are common and if you have an experienced electronics tech around they can replace them for much less money but the tech must have advanced soldering and IC exchange experience.

The STK ics, two of them, can be purchased on line for around $20 to $40 each.

Partstore has two models available - one for around $40 and another for around $55.

The part number is STK392-110 and if you google you can find them for as little as $6/each but I don't recommend the cheap ones as they are not reliable.

It takes a good tech around 3 or 3 hours to take the old ones out and solder in the new ones. Also, it is likely one or two resistors are burnt and will need replacing as well.
