Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
Very grateful for your help!! Tv shuts down after being on for say 4 or 5 mins, sometimes longer. The red light blinks 3 times then pauses for 5 seconds, then repeats. I'm led to believe the problem is on the D G board, perhaps diodes 6301, 6116 and 6117 ?? I'm a handy guy, but not TV's ! where is the "DG board" within the TV? And can I remove easily and repair? Thanks, Keith (Seattle)
There is electric shock risk involve in TV repair.
You should have strong electronics repair knowledge / experience and good soldering skills. Repair your TV at your own risk.
Mostly 3 blinks in this model shows convergence out ICs failure and you need to replace STK 392-110
Its big black IC and TV has 2 mounted on silver heat sink at main board.
HERE is a pictorial web link and you will see how you can replace these ICs.
STK392-110 are available in Part Store.
