You might want to post some pictures of it on here. One of the collectors here may live in your area and would want to buy it or fix it for ya.
The vintage zenith is a good set and has a good picture, b@w or color.

Its a color TV set and It actually was my Aunts TV. Its solid stare and I think its from the early 80's

There were two different chassis numbers using the same modules, TS-915 & TS-919. The 915 went in the large floor model console (Works in a drawer) and the 919 went in the 21 inch table model cabinet (Works in a cage)( vacuum tube Hv rect.). In later years I have seen a lot of xstr leakage problems in the video i.f. and agc sections. They ain't real fussy about sub. types, 2n2222 seems to work well when replacing the NPN's and an equivelant PNP type for the other flavors. Moto started production of the QuasarII sets in 1969 and put them on sale as 1970 models. They were solid state sets except for tube type horiz buffer/vert osc., vert out., damper, & horiz out although they went to a solid state stick rect. for the Hv. These are chassis no. TS-929(table top-cage chassis) & TS-934(console-works in a drawer) with the same modules(all new & no carry overs from TS-915/919). Sometime around 1972, the QuasarII went all solid state with the addition of a switching Lv power supply module(now TS= TS-938). To make the horiz section ss they brought forward the F panel originally used in the TS915/919! This was already a reliable piece, Moto just updated the HOT(s). To make the vert. sect. ss, a new module was designed, the VA. This was carried forward into the next gen. of ss chassis, the TS-942. The TS-938 has the distinction of the first American production set to use a switching type power supply to eliminate the bulky power xfmr while still retaining the elec. isolation virtues of it. Now they're in everything from coffee makers to computers. The TS-942 chassis family, btw, were the last ones Moto designed completely before selling Quasar to Panasonic. Panasonic stayed with the works in a drawer concept for quite awhile putting more and more functions on ever larger growing (and expensive) modules until they too went to unitized chassis in the 80's like everybody else and finally in the end, Quarsar was just a re-badged Panasonic. It could have been worse, I guess? Thanx for letting me bore everyone with this over-extended Quasar-as-I-know-it story.

This info is not boring at all. You ans many questions that I could not figure out. I am seeing two different dates on this set, 1966 and 1968.
One other thing you pointed out was Quasar was a name given by motorola not panasonic. I thought quasar came into play after panasonic took over.
Another interesting thing is there is a chassis coded F 23ts-915 that has a ac line regulated power supply that is connected to the primary of the power transformer. It makes sense to me cause when the air turns on in this house, The picture on my set would cave in. This must have been a correction for this chassis to calm down picture change when the ac line voltage would go lower or higher.
When I was trouble shooting the power supply in this set I did notice a vary strange design with the 35 volt supply line. There is a 35v tap off the secondary winding of the power transformer. The voltage from that tap goes through two choke transformers and two 500 uf caps and then on to the panels that use the 35 volts. When I was checking the voltage line with the scope, The wave form matched the picture on the schematic so I did not worry about it. My question is how can the ac be remove from this circuit with out some kind of rectfier-diode in this circuit. Would any one know the name of this design?
It is funny, I have had this set for many years and never thought what a cool set this really is. Do any of you guys own a 67,68 motorola works in a drawer?
If so I would really like to see it.
Thanks
Ed

Yes 80's tvs are not that collectable, But still, Some people on here really like them.
I never thought people would collect 70s tvs but as we can see people like them just as much as we like the tube type b@w and color. It must be a matter of taste and what the person likes to work on.
A guess would be that the mounts are broken on your aunts set. Could be from rough handling or the plastic on the bezel gave out. {Picture tubes are heavy.}
If you are intrested in repairing or collecting this stuff, Your aunts set may be a good way to start. Look for books on tv repair and roam around the internet. There is alot of info out there that can help you out.
Good luck

Theres a few 70's sets in that house too!

In about 1979-80 when I first started collecting a few old TV sets, I thought nothing about color TV was worth collecting because it was "too new"-after 1950. If I had only known, I might be able to retire on what I could have had then...

I would check them out and grab the ones that are in the best condition.
If you are a young dude and really interested in electronics, You will learn how to repair them. Solid state is not as hard to repair as tube type sets.
Give it a try, Just be vary careful and take your time.
Check out this 1985 magnavox, Chassis#20C601 This is a well made set and has a nice picture.

So many of the color roundies went to the trash and it is getting to the point of finding a needle in a hay stack when looking for them. Most of the ones I picked up in the last few years where in really bad condition and where trashed for parts. I wonder if the value on color roundies will keep going up.

60 days ago i stumbled across a late 70's GE portacolor at a church sale, w/stand for $10!!!!!!!!! And of course, it plays. IKnow Iknow, it ain't solid state, but I love those little buggers!

Amen! This thread is not boring - keep those anecdotes coming!

My contribution - My Dad worked for a Motorola Dealer from 1966-1973, servicing audio. He bought one of the all solid state works-in-the-drawer Quasars from his boss in 1970 or so. Dad used to tell the story about how Motorola's "Instamatic" auto-color button created quite a firestorm with Kodak - they owned the trademark! I guess it was settled through royalties, because it was on sets through several years.

I got my hide tanned one Saturday morning for playing with the easily-accessible screen controls on the back of that Quasar console. Hey! Look! I can make the picture purple! I learned my lesson....

Cheers,

Well, i like 80s sets too, but only when they look like updated 70s wooden sets...

i don't really like mid-late 80s hi-tech sets with squared screen corners like this Magnavox... i'm finding tons of them around, but i usually just get the speakers (when they're decently sized) and leave the rest of the set behind, maybe i'm going to regret this someday... but by now i prefer to save my storage space in the barn for those lovely old school "rounded corners" sets...

Gotta figure the only thing that saved the consoles was the fact it took two people to toss 'em.

I drive past houses everyday in a well-kept Polish section of Detroit. They've all got 2-3 stories and a basement.

Sometimes I wish I had x-ray vision.

I don't like square cornered sets either. Once the woodgrain plastic cabinets went away, that was it for me. I've never liked the black box style and the new flat panel sets don't have any style at all. The real wood consoles with heavily rounded corners or better yet a round tube were the pinacle of television styling. Today's sets are mere appliances.

TV speakers have diminished in quaility too, I once Saw a TV that had big Dual cone Speakers and they had a LOT of bass!

[Kiwick]

there are some newer (80s and 90s) sets that have decently sized and great sounding all-paper oval fullrange speakers, usually mounted on the sides of the cabinet

But unlike 60s, 70s and early 80s sets, mid-late 80s sets with decent speakers are quite rare.

many sets from that era have speakers with foam cone edges and 9 out of 10 are rotten, brittle or even completely disintegrated... and sets with controls and speakers under the screen usually have small, crappy, worthless speakers.
