Discovered bulb had blown out.
At power on button, red light and green light flashed and no picture was present. I opened side panel after unplugging tv and let the bulb housing cool, then removed the bulb and discovered it had blown. Luckily I had a replacement bulb from the purchase, replaced it and it worked again.

No Picture.


I have the same TV, your projection bulb has quit/failed.

A loud pop was heard and the picture has gone followed by a red led fault light clicking on and off.

if your tv is less than 1 year old, and you registered it with Toshiba, you could qualify for a free replacement.

otherwise expect to pay 200.00 for a new bulb from Toshiba.

only good thing is you can replace it yourself, only tool needed is a phillips screwdriver.

you can check EbaY for prices less than 175.00 to 150.00
i am on my 3rd bulb within 4 years....

good luck!
