I too have heard of the 2 capacitors that cause the 7 blink red led symptom. We had our phillips TV 2 years and then the problem. I took the back off our TV last weekend and sure enough on the main board was two capacitors that have bulging tops (not flat like they're supposed to be). All other caps on the board look fine. I have removed the 2 caps and ordered new ones from Digikey. They are 3300 microfarad 10V. Looking at all the other caps on the board - they are all a much higher voltage rating - some even as high as 450V. The 2 bulging caps are only 10V rated. Maybe thats why they are more susceptible to death. Anyway, my new caps should arrive today and I'll see tonight if they fix the TV.

    IT works.  The two caps were the problem.  They were bulged meaning they are blown.  The chemicals inside vaporized and the vent at the top blew causing the bulge.  Replacing them fixed it.  They are 3300microfarad, 10volt, 105degree C.

The two caps may not be together on the board. Usually you can tell if a can capacitor is bad by looking at the top. Most have an X stamped on them. If you see one that is NOT flat then replace it.

I have a rca model led65g55r120q tv flickers and no sound


Check all cables for loose connection, try another input for picture (DVD, BLu-Ray, etc). If none of the other inputs work then it's a panel problem (display) If one or more of the others work then it's a problem with either the tuner or the signal.

How do I determine if it a power failure or if it is a faulty SC board (TNPA5335)?


That does nost sound normal. I would take a look at the output of the power supply. Look at your electrolytic capacitors on the power supply board. Do they look like the top of them has popped up? If so you can get replacement capacitor kits from www.lcdalternatives.com
