We recommend you remove the "Digital In" cable connection from the rear of the TV and turn it back on. If the problem persists, we recommend having the TV evaluated by an authorized service center using the below link.

If the TV turns on then we recommend having the Toshiba Home Theater evaluated. Welcome to Panasonic Online Repair

Will not turn on...just a flashing red light

Evidently this is a common problem with Toshiba rear projection TVs. You might be able to get it working temporarily by unplugging it, pushing the power button a few times, plugging it back in, and then turning it on. Most likely your power supply is going out on you, and should be taken in to be repaired.

Temporary solution found here.

Red power light flashing; will not turn on.

It is very likely that one of the convergence correction chips has gone south on you (either that or a capacitor). What you want to look for is a swollen capacitor , or a burnt resistor near the two large heatsinks on the signal/convergence PCB. The flashing LED is an indication that the power supply has detected a fault, your mission is to determine what that might be. another thing to check out at the fuses on the power supply PCB (these have labels like FXXX were XXX is a number). If you find an open fuse, that will help determine where to look for the fault.
