A 4 flash shutdown indicates a backlight problem. It can be acused by a bad backlight inverter board (the backlight power supply) or by a defective backlight in the panel. There are fuses on the backlight inverter board called "picofuses" which will need to be checked in order to isolate the problem to the board or the panel. If the fuses are good, you have to replace the panel (very expensive!). If the fuses are opne, most likely the back light inverter board has failed.

Panasonic sent a repairman out with the correct part after telling them about the seven blinks. The unit was out of warranty. They rock. Call 800-211-7262 or 800-524-1448 1

This is a difficult question to answer completely. 7 blinks indicates that one of the C boads has failed. however, there are several an SC,SD, SS and SU.
The procedure is to disconnect each of there boards until the blinking is eliminated. The labor charge is usually around 200.00 and the cost of whichever board is bad. Hope this helps.
