Question about RCA P52926 52" Rear Projection Television
I have a RCA 56 inch projection t.v. and i got it from a friend. The picture comes in fine but the colors (red, yellow, blue) are visible. Even when there is no picture and the screen is fuzzy the colors are still there.
If you mean they are separated like a 3-D effect, then you have the typical bad convergence IC problem. There are two IC's mounted on a large metal heatsink, they will have STK392-###, the ### being differant models of TV sets. these are soldered into place and are no usually replaced by the user, unless you have solid state repair experience, knowe how to solder, have a schematic on the set, and know the High voltage safty factors of projection TV serviceing. If you have no experience, please play it safe, and get someone who is trained to service TV sets. Good Luck Please do not forget to rate this thread.

If this tv exhibits signs of colors separating ie when inputs are black screen and menu comes up then this tv has a convergence issue there are no stk packs in any ctc chassis made by rca the power supply board is mounted in the middle of the tv right behind the crts it has a red panduit connector on it if you unplug the power connector to this board and find that your convergence problem hasnt change then the board is no longer providing correction voltage to the convergenece pcb last i looked the redigned sub for the converge power supply pcb was available with an rca number lets face it the rca boxes have pictures of dogs on them
