Red power light continuously blinking. no picture no sound.


It could be the lamp went out and needs replacement. The Toshiba website states when this happens to unplug the televison for 10 minutes then plug back in. If that does not work then try another power outlet. If that does not work then call for service

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)?

TV SHUT OFF WHILE WATCHING. UNPLUG AND THEN PLUGED BACK IN. RED LIGHT CAME ON IN FRONT FOR A SECOND AND WENT BACK OFF. TV WILL NOT COME ON.


power in the tv has nothing related with the DVD. The tv has to have raster (white screen) even without signal (cable, DVD, others) if the tv alone is just having the led flashing and neither sound nor video (black screen) The tv has a short circuit in some of the boards that are part of the tv system. the blinking is part of a protection when the tv was created in the factory. Refer to the technician to repair this problem.

Toshiba 42H81


Won't be any cheaper if you go looking and you'll probably get sold some chinese knock-offs anyway... It sounds like you'll need to replace the convergence amps, both STK392-110 Sanyo originals. Also the tech will test the yoke return path circuits and the resistors therein... Likely s/he'll find that one or more has change slightly in value and change those as well for a more reliable repair...
Hope this helps!

Toshiba 42H81 Blinking on and off light


Very common problems with this TV set. Toshiba even has a technical bulliten on this and several other models of tV set. The negitve terminal of C809 and C810 need to be soldered, as there are no eyeletes in the printed circuit board. This problem could also take out the fuse, F860. Replace if necassary. Good Luck
