Question about RCA P60921 60" Rear Projection Television

1 Answer

Green bowed on screen

The picture was perfect and all of a sudden the green being bowed at the top and Bottom of the screen, I am unable to bring it back with the auto convergence or the manual convergence. From what I have read it is most likely the IC on the CG board, I am familiar with componet replacement and have ordered the part. I have seen some other post about fuses, for some similar models, I would like to know if there is anything else I should be checking or replacing when I replace the IC.

Re: Green bowed on screen

I have basically the same problems. Have yet to fix yet but from information I have gathered it seems that all points to the convergence chips.

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.

Cheap Fix?

I will strongly advise you to replace the two STK392-120 as a pair. and this will cure your bowing picture problem. You may need to re-converge your set. best of luck.

Pt-47wx49e convergence problem

I just replaced the 2 convergance chips, but it did not seem to fix the problem. I then tested all the resistors that feed the convergence chips anf there was a 2.2 ohm fusable blown. IT was R7050 on mine. That seemed to fix it so that I could adjust all the colors through the convergence 2 screen. There seems to be a slight bow near the bottom when you look at the c2 screen, but not noticable when you are watching a picture. Since I got this broken, I am not sure how perfect it should be.

If anyone can send me the service manual, I would appretiate it. Thanks.

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

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.

Screen is bowed (top and bottom) Color has a green and purple tint?

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from and do the repair yourself. Its a fairly easy DIY fix.
