rca r52wh73 convergence	Can't Post

I have a RCA model# R52wh73 that is about 3 years old. While watching it today all at once the picture went into 3D mode. I had another set that had the same problem years ago. The convergence is out. I have read several posts and went through 35 pages looking for more information. I already have the unit apart and have checked the 3 fuses fl221, fl231 and fl251. I have the convergence board and the smaller board out of the set. I would like some detailed information on what to check now and what readings (ohms 200k) I should be getting on the components that may be bad. Any help or direction will be GREATLY appreciated. Thanks

Check the four 220K 0hm resistors RP610, RP611, RP612 and RP613 on the convergence power supply ( Smaller Board) Chances are one is open thats a common problem with that chassis if the convergence option is still visible in the user menu.
