The convergence problem is likely to be in the convergence power supply which is located above and between the two boards which lie flat inside the chassis. The power supply has a chip on it which is a common problem (If it is not the transistor type then change the whole board.) part number on the chip where the metal heat sink is located. Part number may be STK 730-010 or STK 730-130 both number will work and must be unsoldered and new soldered in.

RCA D52W20 52 in. Rear Projection HDTV power light blinking

Liz, yes it is a power supply problem, better question is; low voltage or high voltage power supply ? count the blink code, it should repeat the code, once you have the code call your local tv shops and give them the model number of your tv and the blink amount and they`ll tell you price to fix, gl, video-tek

I will need you to look on the rear tag and let me know the chassis number as that model was produced with two different chassis numbers ITC222 and the ATC221 chassis was used, But the chassis number will be on the tag on the rear panel. Please reply to this same post and I will help you locate the power supply board.
