Question about RCA HD52W56 52" Rear Projection HDTV
Picture is bowed and convergence is out
You need to re-solder the circuit board that contains the STK convergence modules. They're on the center circuit board attached to an aluminum heat sink that's about 8" long and 6" tall, about dead center in the circuit board. You may be able to recreate the problem (hour glass effect) by gently moving the heat sink (which the modules are connected to). This gives the hour glass effect on the picture and the advanced convergence screen. This is an indication that the modules pins aren't solidly connected (meaning soldered) properly. Remove the circuit board and clean the old solder off & resolder the modules pins to the circuit board reconnected the board and then retest by again pushing on the heat sink. This is a caused by a minimum effort (a.k.a. minimum cost) solder job, probably done in some 3rd world sweat shop. The "factory" job was good enough for 3-4 years but the heat (and these modules do create a lot of heat) and stress created from repeated use eventually takes it's toll, weakens the pin connections and our problem occurs. take the appropriate cautions working around the high voltage of the set & use a non-conduting piece of wood to push the heat sink when we doing tests. Best of luck, hope ya fix it.
