This generally indicates an issue with the backlight inverter loading the power supply. The inverter assembly is easily replaced in this panel and costs approx. $90-140 depending on your parts store. Please use caution when working with this component, it produces the very high voltages required to illuminate the screen.
Good luck to you.

The 7 blinks means that the SC scan drive board might need to be replace but only after checking the voltages from the power supply. If the voltages from the power supply are normal, then proceed to replace the SC scan board.

SOURCE: Panasonic TCP58S1 has no pic. or sound. Red light blinks 9 times.

It's dead. 9 Blinks means the display adaptor is dead. If it's still under warranty, you're covered.
