Question about RCA R52WH76 Television

1 Answer

Convergence problem I was given a rca model (R56wh78) chasis # ITC222A. I have read many of the posts, and I have the approximate 300 volts dc to the convergence board, # nna600110b, I cant find any open diodes on this board, but from the looks of things this can be the only cause, question, I don't want to pull the fuse by the flyback, If I have pwr. to the board I would assume the fuse to be ok, so can the board go bad without blowing the fuse, and should I just replace the board or do you think there will be multiple problems after I invest the money for the board, the convergence mode from setup is not showing, and convergence is bad, hope I have given you enough info, thank you

Yes, the convergence circuit can fail without blowing any fuses. These Tvs are tough to repair because the convergence output devices are transistors and there will be other small components damaged as well. Get an estimate from a reputable service center before going any further.

I located the problem with this set and wanted to pass it on to help anyone with this problem. the chassis # is ITC222A and the problem turned out to be a fuse on the High voltage board. There are 3 fuses that sit next to the flyback transformer and the middle fuse (400 ma 125v) was blown.
