Question about Panasonic TH-50PC77U 50 in. Plasma TV

Open Question

Panasonic Plasma TH 50PZ700U - turns on with solid Red Light but with no sound or picture.

I have a Panasonic Plasma Model TH 50PZ700U that turns on with solid Red Light but with no sound or picture. Eventually after a few minutes of being turned and left on.... it blinks 13 times. It appears to be in Standby.... not sure. I can then use remote to turn back on. It comes up solid RED on Power indicator again with no pic or sound. I cant turn off using remote after that I tried using Technical Guide Plasma Full High Definition (GPH10DU Chassis) and it does not give me much to check whats causing this. Any hints and tips to determine what to look for and determine problem will be much appreciated.

SOURCE: TH-42PZ80U Panasonic Plasma, red light flashes 10 times

Panasonic said "A" board,
A board SOS Detect (Explanation)
10 Blinks SOS: The voltage regulators IC5400 and IC5401 in the A board generate SUB9V and SUB5V. The 9V and 5V from these ICs are monitored by IC1100. Any abnormality on the SUB9V or SUB5V lines, triggers the shutdown circuit and the MPU shuts down the unit. The power LED blinks 10 times.

But need to measure the connection SC2, if it short, it will be the SC board.

The knowledge obtain from: Real case of repair by myself.
Information from Panasonic training manual.

If you remove the back panel and check on the power supply board, you will find a couple of bulged caps that need to be replaced, or just replace the power supply board.
