Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
This blinking is unfortantly not an error code. The one thing that you can determine from this blinking is that the main fuse. and the sub power supply is functioning. The blinking is also an indication that the cpu of the set is getting power.And its not simply a fuse.What is happing is some voltage or current is not right and the cpu is taking the set into shutdown for safety. In diagnoseing these sets first uplug the set and allow them to set for som time. not that long. Then plug them in and attempt to turn it on again. DID you hear a click? how about some high voltage static. The most common faliure of these sets that i have seen at the shop is the faluire of the high voltage transformer known as the flyback and when this fails it also takes what is known as the horizontal output transistor. The cpu will shut down the set for about 25 different reasons. Technicians have a computer interface that they ussally use to diagnose the problem
