Question about Televison & Video
By the power button is a red light that is continually flashing. The TV will not turn on manually or with the remote.
Unplug the TV for 2 minutes and plug it back on.
It should work.

Need to vacuum the dust out of the top filter at the very top of the TV... build up of dust will turn off screen and start flashing light. At some point, TV will break, but this helps us solve problem

If you pull the back off the set and look at the front left circuit board there is a small fuse there. It will probably be open. If your lucky, try another fuse and off you go. If your not lucky you have a shorted component in the power supply area of that board. Probably a voltage regulator of diode shorted. Good luck

This just started for me too on a Toshiba 36" crt.. I found that waiting for any amount of time didn't work for me.. I actually got interesting and repeatable results by shifting the TV around where it sits!
By moving the tv (pushing from the front right bottom) I found that I could bring it back from the flashing red light business.. moving it forward would cause the flashing red light to happen again.. implies to me that there might be a loose board or cable or solder in the tv case that is causing the fault protection to fire off.. Kinda makes sense for me since I just moved this tv from mainland to hawaii and it probably got jostled around a bunch.

Try this - it worked for me. Unplug the TV, unhook the cable, and let it just SIT for 24 hours. Evidently, this FLASHING RED LIGHT OF DOOM is the TV in 'standby mode'. The standby mode evidently 'times out' at 24 hours. This has happened to be twice before I finally figured it out. Wait the full 24 hours, then plug the TV set back in, hook up the cable, and turn it on using the on-set power button. From now on, use the REMOTE to turn the set on and off to avoid the TV going into standby mode. Oh......another word of advice....don't ever buy another Toshiba TV....
