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

My Toshiba TV keeps shutting off and the red power light blinks on and off. I unplug it then plug it back in and about 1 min. later it does it again. I have a 42" projection tv and the power shuts off and the red light blinks. I can unplug it and turn it on for a bit and it does the same thing again

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)?

    I have had the same problem with my Toshiba 40WH08B rear projection TV and I fixed it for £40! You can do the same if you can solder or find someone who can do this for you.



    Let me know if you want to give this a go and I will post instructions.

The power light keeps flashing and the tv won't turn on. If you unplug for a minute and hit the power button it sound like it is coming on then it shuts off and the red power light flashes slowly. The TV is a Panisonic 1080i HDTV, about 6-7 years old.

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.
