Blinking red light

    We cannot get tv to turn on!!! If we use the on/off button the red light

    starts blinking and we also get a clicking sound. In trying to get the tv

    to turn on, we unplug the tv and wait 10 seconds and plug back in. This

    can sometimes take hours. Please let us know what to do and how

    much it would take to repair and if we could possibly repair ourselves.

    We have only had this tv for probably five years. I bought it brand new

    and spent $2,000.00 on it. I cant believe that this item, costing as much

    as it did, would only last 5 years. If that's the case, you better believe

    I will never buy a Toshiba product again and let everyone else know

    what a bad product it is.

    Please get back to me

    Have the same problem with my Toshiba... It's ashame that toshiba has not recalled this problem with the blinking light burn out .....

    I've had the same problem. Its happened at least 4 times now and I'm tired of it. Toshiba knows they have a problem. Maybe when it burns someones house down they'll decide to recall this.

    Same problem - can it be fixed short of taking it to a TV repair shop. I've had good luck fixing other elctronic units as long as they're discreet components.

    Me Too, I replaced the convergenvce chips about two years ago, looks like I'll have to replace again. This time it happened when I left the X-Box on overnight.

I had the same similar problem and through the process of unplugging and re-plugging the set I finally got the set to come on and stay on, then smoke started coming from the back of the tv from a convergence chip. What I found out was that the chip shorted out tripping the tv safety and I overcame that burning the bad chip completely out eliminating the short but with the blue color off. The chips generally are only $5-10 from -
 BTW - I think this is one of the better picture quality projection tv's out there compared to my hitachi, sony, and rca and even a friend's mitsubishi.

No Picture - Sound

I just had this problem fixed. In my case, it was because the insulation on the CRTs was cracked, and when it would warm up, the shielding would separate and would let 5000 volts arc across the main board. This, obviously, damaged the board. The tech didn't catch the arcing right away, so they replaced the main board twice before they used a high-temp RTV to patch the insulation.

The power-cycling was a result of the damaged board.

The point of this story is that the broken part may be a symptom of the real problem.

I hope this helps someone!

TV is not powering up and red light keeps flashing

I had the same red blinking led problem on my Toshiba Theaterview tv. I resolved by:
- Unplugging the tv.
- Press several times (3 or 4 times) the tv Power button.
- Plug the tv back in and press the Power button once to turn the tv worked!!!

I've had the problem before and tried unplugging the tv for a couple of days and that had also worked, but I this recent solution seems to be faster.
Good luck!
