The screen on my TX-R3079WH TV suddenly went totally black and had no sound. None of the troubleshooting tips in the manual helped. The red light blinks about 5 blinks, pause, 5 blinks, pause, etc. The screen is totally black and there is no sound. The TV is getting power and seems to "react" to the remote (red light blinks), but there is nothing but black screen. The TV is 3 1/2 yrs. old. Help!!!

If the crack is in the glass - your set should be considered "totaled". The cost of replacing the "display" will probably be more that it worth. If you are under warranty, contact the seller immediately.
