95% 0f the time when this happens to a toshiba projection or regular set, the power regulator IC is bad. It is a componet that should be replaced by a service technician as there are too many points inside this set that can zap you and hurt you. If thats the only problem your talking in the range of 175 to 250 to repair this set. Good Luck

Here's a solution that I received from an TV expert in another website: "This sounds like a power supply problem. i have seen it several time on
your model. i would not keep trying to turn it on it might damage
something else in the tv. the reason it is shutting off is because the
power supply is putting out too much voltage. a repair cost will range
around 300-400. this is a great model and well worth a repair. here is
a web site that might help you in finding a repairman.

This just happened to me and it was the bulb. A fast easy way to check is to unplug your tv, remove the side door on the left side (left side if you are looking at the screen) and remove the 2 screws holding in the bulb case and remove. If there is glass in there and the wires are just hanging out inside the bulb, its done. Replace bulb and all is good again.

If the relay clicks you most likely have a leaky diode or bad transistor in the stand by or start up circuit. There is a manual available for that model called. Toshiba Power Supply and Shutdown circuit Troubleshooter. Its available at the following link. It gives step by step instructions so you can figure out exactly whats wrong with your set. The site emails it too you after you place your order and they also provide free unlimited tech support so you will have a resource for help if you need it. I am one of their on line support techs. I highly reccomend that Manual to any one with a toshiba that will not power up. Here is the link.
