This is a common problem. Your convergence has gone out.

Common symptoms are...

2) Warped Video
3) Convergence menu does not adjust the red or blue correctly.

My 52" RCA P52937SG screen bows on the top and on


What you are describing can be due to a number of different settings.

Focus on the red and green guns
Sharpness on the red and green guns
Horizontal position and size
Vertical position and size.

Please consult a professional for adjustment on these items as they are all near or connect to parts that have Hazardous Voltage.

Convergence


Replace Both of your STKs big black chips Stk392-110s use STK392-180s better ics Electronix Part 1-800-223-3205 for parts .If you need anymore help let me know. Cost in repair shop depends anywhere from 325.00 and up.STKs (180s) $9.99 each. You will also need white heat sink silicon to put on back of ICs.

Double focused, red and green, bow in picture top and bottom


hi
You have a convergence problem
If the set has auto focus and will not complete its cycle.
The Auto focus module is bad, (expensive)
If it completes and the problem is still there.
Then check for bad conv. drivers (stk****) or cold solder joint on one or more of the 3 drivers pins.

Tv is messed up


I got a question.

Do you have any stereo speakers anywhere near your television?

This sounds like something a magnetic field could cause from speakers being too close to the tv.

If so try to relocate them and see if the problem goes away.

Sounds like the blue convergence circuit still not working.

Assuming both IC's are good, look for open soldered-in pico fuse.

Once bowing problem is solved,then convergence should adjust ok.
