Toshiba 57HX83 tv Flashing back and forth to black

I have a Toshiba 57HX83 tv and it is flashing to a black screen off and on. The audio stays, but randomly goes black and then comes back. There are also some wavy red looks that come randomly (kind of how it used to look when getting close to a station as you tuned it in).

With the back off you should be able to see the three large round lens this set should have---black cylinders with a glass lens--if real dirty they can cause picture to look darker and dull---I presume same with DVD player etc connected to rear input.

the lens point up so get dusty, the mirror points down at a angle and rarely needs cleaning.

The screen is scratched and stained- I would like


that is a good idea, but expensive.

if the screen is that bad, you may want to try with some commercial available polish for glass or plastic, like plast-x. you can get that in any auto parts store or your local walmart...

Toshiba 36HF71 has sound but no picture


Same problem with mine. Relays click, sound, no picture and a flashing power LED. I finally found a schematic online. I went through the high voltage circuits and found the power transistor 2SC5570 was shorted out. There is also a pico fuse in that area but my was not open. I replaced the transistor and prayed the flyback transformer was not shorted. It wasn't, I'm watching my old 36" right now. Not a bad fix (17.00) bucks. Wonder what a service tech would have charged ;)

Flashing light


this unit will have what is called ik protection wich means that the picture tubes are constantly monitor with this system all the way to the video procesor so the picture will desapear to a black screen even if the audio is ok,there may be a solution if contract a tech like me to adjust the bias so that compensates the drives to the pictures tubes since 1 or the 3 pt are week at this point.
