Got a high end Zenith TV, think it's a 29". Looks to be somewhere from 90-94 model. S-video, PiP, lots of dandy stuff for a CRT set. Don't have the model number on hand, I'll post it later. Hasn't been turned on in about 5 years. The picture is darker than it should be and a little blurry. The CRT filaments do not appear to be as bright as they ought to be. Tried adjusting the focus and brightness on the flyback without much success, only washed the image out more. Is it likely to be a junker, or maybe something wrong in the flyback or the power supply of the CRT? The thing I don't like is not seeing bright orange CRT filaments. I think that may mean trouble. Too bad, it's a nice set otherwise.

No such a thing as High End Zenith... Sounds like the regular Zenith CRT failure..
Bright orange filaments usually mean a problem in most standard picture tubes.
Zenith Tvs of that era are known for CRT failures, probably a junker.

Look for (4 - 5) 120 Kohm resistors on the CRT board that changed value... usually well into the Megohms. After changing those resistors most Zenith's appeared okay again.
Well, there's a lead to try out. I'll let y'all know if anything comes of it. Thanks!
