Zenith Projection Tv Set Model number ZB4685T no Visual

Hello I have model number ZB4685T of the projection tv sets and I have a tv will turn on, I'll hear the audio just fine and then the video will show for a min or two, fade, and then the screen will go black. I know I have power because I can hear the audio crystal clear just no video whatsoever. Anyone have any idea what might be wrong and how to fix it? Also with it being such an OLD tv set didn't know if anyone had any suggestions of places to find possible parts for the tv set. Thanks

Since this is a CRT based set, there could be a number of problems. What exactly do you mean when you say that the picture fades? Do you loose contrast and the picture gets lighter? or does the picture darken toward black?

Parts are still available, so this can be fixed. If youfeel you want to attempt this yourself, please supply additional info and we'll walk down the diagnosis path.

Is this a HD TV?

No way I can tell since you did not post a brand or model number here, with the model Number Google for specifications or specs which usually brings up reviews of the set including if it is HD or not.

Why won't my toshiba tv model 43a10 display color

It is by the model number a rear projection tube set--Look to see first if when a DVD etc is played you have color or not (via audio video jacks on rear of set)

If you do the set's color circuit is ok.

If using a box unplug it and wait--plug it back and let the box boot up.

If none of this helps the and the set has no color on all inputs you have some problem in the color or chroma circuit in this set---it is very rare for this to be a circuit problem.
