    I had this same thing yesterday. The troubleshooting secion of the manual says to unplug the tv, wait a few minutes then plug back in and try again. If it doesn't come to life call a technician. It seems that the flashing light is a code to identfy the source of the problem. In my case 5 flashes- pause- 5 flashes. It means a computer board burned out---------------------------------- $500!!!!!!!!!!!!!! ouch!!!!!!!!!!!!!!!!!!!!! The TV only cost me $850!!!!!!!!!!!!!!!

    I have a Thoshiba Plasma 42" (42HP95), 3 years old that will not turn on this morning. I was watching it last night and all was fine, this AM I tried to turn it on and the power light flashes but the TV does not ititialize at all. I unpluged it several times, held the off butten for 10 seconds hoping for a reset, but nothing works. The fan does not run either, so I surmize the power supply unit sences an overload. It does make the familiar clicking noises when it is plugged in to the power source. I have been a technition for many years, but have been retired since before Plasma units were a part of the electeronic landscape.

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....

I'm having trouble with my Toshiba 42HL196 TV. It won't power on. There is a flashing red light on front. I've read the manual and done everything it suggests with no success. I've checked inside the tv...

SYMPTOM: Won't turn on or intermittently won't turn on, Red LED Flashes.

CAUSE: Loss of Main Switched Power Sources. Standby power is OK.
SOLUTION: Replace Regulator IC Q820 with Toshiba Part # 23135094

I don't know the exact codes but here is the search method. Make sure the device is on. Hold down the tv (or whichever device your trying to program) button and the power button simultaneously until the red light stays on solid. Then press the power button, it will flash one time, and keep pressing slowly letting it flash until the tv turns off. Then press the stop button...and it is programmed. Thanks

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.
