FYI - that is a 1989 Digital (9-700 module) F-Line projection set. Parts are scarce... sets weren't supported well by Zenith.

Pretty rare -I've seen exactly one, on the curb.

Been to long but I think its a DV set, could be wrong.
If its a "Digital System 3" it will say so on it. If so parts
are scarce. Only the highest ends sets had it. Most problems
were in the "analog" parts of the set so usually can be handled.
Problems in the digital part can be a bitch & since the sets were rare
& didnt fail in the digital parts often. I worked at a major Zenith
dealer & I only worked on maybe 10 of them.
They were the most complex set at the time & ran very well. BUT
the limited amount of them caused us not to get the hang of things.

These sets were not digital as in HDTV. They used digital processing
after the IF stage for audio, video, color, sync, then converted back
to analog for the final stages. Other sets I worked on with it
were Toshibas & NEC's. IIRC MGA & Panasonic used it also but
I never seen one. IIRC all used the same chip set from ITT.

One other thing it may be is a Bose audio set. Top of line &
limited distribution. The audio will knock your socks off & could
be run without the TV to use it as a stereo amp. Again it will say BOSE on it if it is.

It would be nice if some of these sets were saved, a bit of a milestone
in color TV.
Thanks for the memories.

The real problems with those 9-700 sets was the lack of service bulletins, training and support from Zenith. First service seminar I went to on the System 3 digital sets, and the reps stressed the digital module would be a swap only. When the service data came along (CM-143, IIRC) the schematics were there for the 9-700 module, but no values, and PTS didn't rework them. A year later, Zenith made the 9-700 early mods a non-stock item. We suffered through a dozen sets, thanks to a network of doctors that had them in their offices. H alpha suffix - makes it a high end/hotel/motel/hospital model, and those were really rare.

I worked on a few. It was mostly hit or miss until the problem was solved. I had every part for them from modules to chips. I hated them. When I closed my shop, all of the parts ended up in the land fill.

We had everything also. Boards, chip kit with logic probe etc.
Hated the fact that the boards came without chips. Same with
the 9-181. Try an IC, change the board & swap IC's and
keep track of things. All our stuff went to dump also
Sold abt 12 of the table models first year only a few needed service,
audio & vert. Never junked one. Last one I saw was abt 2005
a Bose table model. Got the set working but it had other minor
problems. Told them we needed a blank check & $250 down
to fix everything, they took it away just running for $75.
Still had a good jug, I felt kinda sorry for it.

What parts do you need ?
Best bet is to find another one with the same modules.
Look at 27" & up including projo's of that vintage. Be sure it
says "Digital System 3" before looking at them.
Thats assuming it is a digital, you never said.........
