Red light flashes 4 times

I would guess a power board failure. The blinking light is an error code.

hey there! i finally figured it out!! If you have a computer hooked up with the HDMI cable in the back of the TV and the computer is either on screen saver mood or sleep mood then it is trying to make the television go to sleep aswell. So the only way you can have a computer hooked up to the TV is if you use the front HDMI hook up. pretty weird but thats what was wrong with mine. Hopefully that was the problem :):)
thats pretty normal, it takes a good second or two to warm up and the display to turn on(at least0, you get the green flashes as you hold for on, 1 sec is a long time at times, lol, be patient, no problem with your tv!

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.
