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.
