Question about RCA D52W20 52" Rear Projection HDTV-Ready Television

1 Answer

My PT-53TW53 Panasonic

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)

Be aware:-
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.

Good luck.

Panasonic PT-53TW53; Red shadows appear and then the t.v. shuts down.


The convergence output IC's have failed. Only fix is to replace them. These are large amplifier IC's bolted to heatsinks and have a high failure rate in all projection sets.

Standby light blinking 3 times means a convergence error. The two convergence IC's need to be changed Panasonic part# C5AA00000203 (do not substitute with a generic STK#) This is about a $300-$400 repair.
