We called sony support and all they told us is to unplug. this morning when i got up the sound was there no picture but after cutting the tv off several times the picture appeared. now to come back home and have the same thing happen. after cont cutting off and on the picture will appear the sound is fine. the red light does not blink after the tv picture appears. when you first cut the tv on it blinks then. please help??? after the picture appears i have cut the tv off and on and the picture comes on its when you cut the tv off for a period of time there is no picture but we have sound.
The TV is about a year and a half old. Turned it on and after a short time I heard a loud pop and then the picture went. When I turned it back on the picture is hard to see and is dark and has no color. The sound is fine.

Re: no picture but has sound
The problem can be caused by a bad sustain board (Ysus Zsus) , the popping sound is often caused by a capacitor blowing up. The TV must be taken apart and tested before eventually replacing sustain boards.

It does sound like a power supply problem but that can be misleading because a problem somewhere else in the TV can be "holding down" the power supply. This can usually be determined by using some isolation techniques.
