Convergence amp ic bad
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.
Don not run the tv till you have it fix you will cause more damage!

we unpugged, checked all the plugs in the back of the tv, played w. the remote)tried every function at least twice,and we tried the reset button next to the power button, now we dont have any other ideas.
Same Problem as other post! Wave forms at the upper left hand corner of the screen, though it appears to be the red lines that are a problem on our set. We have had the tv for 5 yrs with no other problems. Do bulbs need to be changed?
