Re: toshiba projection tv

Unplug the TV from the outlet for about 30 seconds. This will reset the microprocessor. Re apply AC and power on the TV. If your lucky the set will come on and play. If not, the red light will start blinking again indicating shutdown. There are many reasons for the set to go into shutdown, but one of the most common cause is failure of the convergence output IC`s. If your TV is in shutdown, you will need to find a qualified technician for proper diagnosis and repair.

We have a red light flashing on the front of the tv.It shut off and we don't know how to turn it back on.

A red flahing light is sometimes a Standby Mode. Does the power button on the remote turn it on.Sometimes the remote has multi funtions and you need to select TV for it to work.Try using the Power Button on the TV.Good Luck.

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.

TV turns off and power light blinks unpluged andd still does it.

Likely to be the STK convergence chips causing a protection circuit to switch the TV off. Have you got any onscreen convergence problems (i.e, colour fringes)?

No video, shuts off then back on

I checked Toshiba's website and found the manual for the set. The self restarting was indicitive of a lamp failure. The red light was solid while the green light blinked. It would then restart 8 times before both lights would then begin blinking.

Red light bflashing

Sometimes a power surge will cause a projection back TV to shut down and flash like that. If you unplug it from the wall and let it sit for a minute and then plug it back in, it should reset itself. If that doesn't work it will probably have to be serviced. If it does work, make sure you get a nice surge protector so you don't fry your TV.
