52" RCA P52771AT with PTK178LB chasis - Blue Halo

From reading this and other forums, it appears I need to replace the convergence ICs in this old projection TV. Can someone point me to a a vendor for these chips?

Also, any help identifying these inside the chasis will be greatly appreciated... I'd like to get another year out of this set...

Thanks in advance,

Unfortunately, I do not think

Unfortunately, I do not think this set has these convergence IC's. RCA sets have discrete driver transistors for the convergence drivers instead of IC's. You will need to trouble shoot the convergence driver board and find the bad components and replace them individually. if you have no solid state printed circuit board repair experience, I'm afraid this is not the job for you to attempt. Play it safe and call in a pro to assist you in this repair. Good Luck
