    power will go on for a short while (second or longer) and turn off, power light
    will start flashing. the only thing i can do is unplug the tv and latter plug it back
    in again. Sometimes this will work and good for while, and sometimes it will not. Any advice will be welcomed.

    We have the same problem. Our TV light flashes, but will not turn on. First time it happened, the TV came on when I unplugged it and later plugged it back in. This time, nothing. Any help is appreciated.

    Same problem, I have a 98 Toshiba Theaterview 50", I unpluged it and it sounded like it was going to come on, but the red light just flashes, I think it needs the transformer replaced or something in the power area.

    turn tv on cuts off few seconds later think its a fuse but dont know what looks like or where it is on syphonic tv/vcr combo

  • Anonymous Dec 06, 2008

    After a couple of years of working great, problem started a couple of weeks ago, powered up and down very slowly. Thought it might be batteries in remote, but that didn't help, now it won't power up at all most of the time. When it does, works fine as tv or DVD player. Also I don't get the flashing light others described.

There are two main causes that come to mind for the problem you are describing, unfortunately it is kinda a **** shoot as to what one will be the exact cause of your problem.

The first would be what is called the Z801 module, they were very common to go bad and randomly cause all kinds of weird problems. The Z801 is a protection IC, I recommend you start with replacing it. The part number for this is HIC1019, you can find this many places online, I recommend

The second would be the convergence circuit, it is common to go bad intermittently and cause this set to shut down. If this is the case I recommend you replace both convergence output IC's The part number for these is STK392-110 you will need 2.

I have the Toshiba Theaterview. Was watching it when I heard a sound and the screen went black. The Red Light will come on and glow steady and you hear it click when you try to turn it on or off but...

Something is causing the TV shut down or go in to 'protect' mode.
It is unusual to actually hear a component inside the TV go bad, but you obviously did. Probably in the main power supply or something that normally uses a higher voltage in the TV since you heard it..

Have an older Toshiba theaterview TV, when turn on, we have no picture, no sound, just black screen and blinking red light that just continuously blinks.

Theaterview suggests a rear projection--in that case it most likely is in the convergence circuit--unsolder chips (convergence) and see if set turns on.

Some of their regular TV sets (picture tube) if the light is just blinking means the same thing=shutdown because of a short/problem but a model number would tell me which you have.

Toshiba TheaterView keeps shutting off!

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
