Picked this up today for 10 dollars at a thrift shop they had 2 of them but it was 25. anything that i should know about with these sets bad flybacks etc.... It has two din connectors on the back opened it up and found it is a video/audio input or output i dont know yet.
Do these sets use infrared remotes or the old clikey type?




btw the picture is not as bad as it shows in the pics it is actually very good!

Nice set! That one looks new enough to use an IR remote. I think '81 was the last year for ultra-sonic remotes.

is the square at the upper right hand corner an ir sensor or a channle display?

Look at it close. Use a flashlight and see if if looks like a LED display in there. Will look like 2 8's. If not, probably the IR receiver. Could be both in there/ Who knows!

I love Zeniths like these.

It might be the camera, but it looks like the green gun is getting weak though.

I thought the same thing. A minor screen adjustment will make it better.

it actually has very good picture its just my crummy 2 mp phone camera.

Zenith also offered that set with a single knob electronic tuner, and the old school click-stop knob tuners. I have the later and it is a good set.

My first ever TV used a knob style electronic tuner. I miss that TV. :( It was a cheap Sears TV but it was a beautiful looking set. Had a Zenith like appearance to it. At least I felt it did.

Just remember, inside a cheap Sears tv hides a Toshiba or Sanyo, well made set :D

Thanks for that Zenithfan :banana:

Makes me feel better about the little Sears 9" color set I picked up a few weeks ago. I think in another thread it was determined the model number told me it was a Toshiba set. It certainly does perform okay since I cleaned it up and it stopped "snapping" from a capacitor to ground.

I haven't found a place for it to "live" in the apartment yet....so it sorta WANDERS around the front room on a TV tray for now. I turn it on often INSTEAD of turning on the big 55" Sammy LED set. For some reason....it just feels more personal watching a smaller set that is closer to wherever I'm doing some little task.

does anyone know it the redi port on the back is for av input or output?

From the factory, those were connected to nothing. The "redi-port" was simply a plastic knock-out hole for optional accessories to be installed inside the TV. I think the most common thing to be installed here were security alarm sensors for such TV's that were used in hotels, motels, hospitals, schools, and other commercial interest.

it actually has a 3 pin din connector i will try to post a pic.

here are the pics.

here are the pics.

I noticed a three-pin connector on the same panel with the Redi-Plug which, as radiotvnut mentioned, is just a plastic knockout plug covering a hole in which other accessories (such as security alarm sensors and the like, as radiotvnut also mentioned) were installed. The 3-pin socket is labeled "antenna switch accessory" -- I wonder what that is connected to and what its function was. Obviously it is for some kind of antenna switch, but I wonder if this series of Zenith TVs actually had antenna-switching systems (operated with the remote or by way of a switch on the front of the set) or if this is just a dummy socket not presently connected to anything, but could be if such an accessory became available some time after the set was sold.

Many Zenith TVs of the 1980s, especially those designed for commercial use (hotels/motels, schools, hospitals, et al), had such plugs and sockets for accessory devices such as in-house cable tuning adapters, alarms, etc. LG's website (www.lg.com or www.zenith.com) does have a section on their commercial products that states such TVs are set up for in-house cable tuning, in-house information channels, programmable (from a central location) channel lockout, and a host of other features not found in televisions designed for use in private homes. Some of these sets could even be remotely (from a central location) programmed so that the volume could not be increased beyond a certain level; this feature would most likely be found on sets installed in motels and hospitals, so the sound would not disturb others -- even if the set's volume control was turned to maximum.

well i just checked inside and there are three wires going to it a yellow one a white one and a red one i will get pics in a min.

here are the pics of inside. what i thought was a channel indicator was actually a IR sensor. I was hoping there whold be some sticker inside saying that the sat had had an alignment and new caps done in 2011...:scratch2:
The last pic is showing where the antenna trner jack connects to the tuner board.

I've seen a similar plug used on hospital TV's to connect a pillow speaker. The ones I remember had a volume control knob on the pillow speaker and a channel button that would advance the channels in one direction and turn the set off.

I would think that it would be for something like an antenna disconnect or maybe a close/distant switch or something like that.

just went to putt it back together and look what i see a jumped resistor with a diode.

It looks like the REDI-Plug is not knocked out, but that little 3 pin din is for an antenna switch operated by the set.

So what exactly is a antenna switch?
