I have a toshiba theatre view 52-54 in.? There is no picture-it seems like the tv is off but the power button light keeps blinking. Tried using remote and button on tv. neither works.

Same problem with mine. I find that if i unplug it and let it sit for about 15 minutes ( let the capacitor drain?) i can plug it back in and it automatically comes back on and works fine till I want to turn it off again and it goes right back to the flashing power light.
I bought an on/off remote for the wall oulet and it makes a great work-around.
