Your convergence amplifier has failed.
There are a few things that usually cause that in that particular chassis design, the most likely one being that you have lost part of the power supply to the convergence amplifier power supply board.
You may be able to repair it yourself if you're good at soldering, and dis-assembly / re-assembly.
Look for a 400ma fuse that's opened near the FBT, and re-solder all the connections in that area. Also check to see if any diodes have shorted around it too.
Good luck.

Do you have the convergence option in the customer setup menu? IF YOU DO NOT consult the tips and tricks section of this website for the article ' "The fl231 fuse problem" If you do then it will need some more trouble shooting

R52WH74 WONT CONVERGE

first question is the picture also bowed in on top and bottom. if so you may have the common fl231 fuse problem if you do consult the fl231 problem under the tips and tricks section. if you dont then you defently hav a convergence issue. the thing to look for is under setup do you have the autoconvegence option if you dont then you have that problem.

Rca model r52wh74

You could get into service mode and set the convergence. The only problem is....RCA decided to remove it from the menu for the R52WH74. It only runs 1 time during the first setup, according to RCA Customer Service. This is the 2nd one I've bougt in 6 years. Enough RCA Garbage!
