hi there, have the same kind of problem twice so far after was bought for me as x-mas present (although my viera isnt plasma, its an LCD TX-32LMD70A)..
I Pulled out the mains plug for about 10-20 seconds and then plugged back in (power button at top was pushed in, in the on position, so when the power was on, the tv just goes straight on). It then worked.
i would however like to know why this happens ( i really hope this isnt a hardware problem, as like many others... its only months old!!)
hope this helps

I had the same issue twice with a TH 42PWD5. turns out it was my UPS that was killing the switching power supply. Warranty covered it but when I removed the UPS not a single issue in 3 years.

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.
