TRY LOCATING THE COLOR CONVERGANCE IC CHIP ON THE BOARD , IT WILL BE MOUNTED TO AN ALUMINUM HEATSINK PLATE ON THE BOARD. LOOK FOR IT TO BE ATTACHED WITH A SELF TAPPING SCREW AND SPRING CLIP. THIS CHIP IS RECTANGULAR AND HAS 11 CONTACT LEGS SOLDERED INTO THE BOARD . ORIGINAL EQUIPMENT CHIP IS STK730-130 , AVAILABLE THROUGH SUBURBAN ELECTRONICS WHOLSALE FOR $4.59 +SHIPPIMG AND HANDELING. A TV REPAIR SHOP SHOULD BE ABLE TO SOLDER YOUR NEW CHIP IN FOR YOU,AND IF YOU HAVE SOLDERING EXPERIENCE REPLACE IT YOURSELF THAT IS WHAT I DID AND THE TV WORKS GREAT!

I located the board at PTS Electronics. Mine was the digital convergence board.
A little pricey but did the trick. Recommend that if you do not know how to drain off the capacitors. Let theTV sit unplugged for 3 to 5 days to drain them down below a possible fatal shock level.
Recommend taking good digital photos for your reinstall if you have no schematics or real electronic experience. Priceless advise !!
Do not touch any settings to try and adjust without knowing the original factory settings. It will get expensive to have a tech readjust. Lots of time to adjust and the tech knows you were there. $$$$

How to install a convergence kit in R61WH76 chassis no. itc222a


That model doesnt have the normal convergence components that nost other sets have. There are no convergence ICs the convergence is actually affected by three boards within that chassis it can be deflection board related, Convergence power board or the convergence amp board. Based on your TVs setup menu diagnosis will determine wether a component needs replacement or wether a circuit board will need replacement.

Where is the convergence power supply located on a RCA P52960?


TAKE A CLOSE LOOK AT THE LABEL ON THE BACK OF THE SET WITH THE MODEL NUMBER, IS IT MARKED PTK195?

THE PTK 195 uses a power supply mounted above the main boards and is about 10 inches wide and 4 inches deep.

It is very common on this model for one of the ten diodes to be shorted; confirm it is a 195 chassis and I will tell you how to locate the two diodes that fail. They supply voltage to the convergence circuit and I have seen dozens where one of them shorts.


Let me know what you find; is it a 195 chassis?


If this information has helped you rate this solution as I do this here for free, rate it "very helpful".

If it is a 195 chassis let me know and I will pinpoint the location of the two diodes and tell you how to check them.

Misconvergence


Convergence on RCA P56940 chassis PTK195 can only be done by service center with RCA Chipper Check computer interface box. Sounds like possibly missing -15 volt or +15 volt supply to digital convergence circuit, bad i.c.'s U19503 or U19504. Supply voltages come from regulator supply transformer T19701 diodes CR19707 (-15 volts) and CR19709 (+15 volt)
