Picked up this 1981 TMK set last weekend, don't ask me why, felt sorry for it I guess.

It came with it's original box but not all the packing, the 12v car cord is there along with the ac cord, it's pretty clean cosmetically but needs a good cleaning with some 409.

It had some massively corroded D cells still in it, they didn't do much damage though, just a little corrosion on a couple of the contact springs.

The CRT may be shot, it's tracking heavily green, it may adjust out or it may not, I have to remove the back to find out.

It took several minutes of running before the horizontal and vertical would lock in, probably some caps needed to reform but it seems pretty stable now, it just looks really sick because of the green cast.

If the CRT won't track it'll be going back to the Thrift Store, it may go back anyway because I don't really need it, want it, or have room for it, but I just like to tinker with this stuff sometimes. :yes:

Believe it or not TMK's were a good cheap set. We were
shocked that they ran a good & fast parts dept.
The earlier ones broke dial cords but it came as an assy so
a fast easy repair. Just a few screws....

The fumes from the corroding d cells, might have affected the settings on the CRT board. Take it apart for S&G's and look. If you can't correct it, then returns it.
Most thrifts around here sold those things for a buck or two! :scratch2:

I paid $10 for this one, high considering the other Thrift Store often sells working BPC sets (and Trinitrons) for as little as $6.98.

This particular store stopped selling CRT sets some time ago but they still have the occasional small set like this, guess they figure there's some collector interest.

I got a later model Portacolor from them a few years back.

Opened it up tonight and tweaked the screens a bit, it didn't take much, plenty of range left. Touched up the focus also and sprayed some Deoxit in the controls, well actually sprayed Deoxit at the controls, they are kind of buried so I just had to spray and hope for the best, it seemed to work as they got easier to turn.

This thing is really well built, old school quality and packed like a can of Sardines. One of those sets you don't really want to take too far apart because you'd never get it back together again.

The CRT has an Orion label, possibly the manufacturer of the entire set?

I also sprayed the cabinet cover down with some 409, it's cleaner now, I think some of the film was corroded battery funk, there was some on the screen cover too but it wiped right off with water.

The movie is widescreen DVD of Midway, not a good choice to demo a 5" set.

Toyomenka made the set. Big electronics firm in that era - made a lot of domestic Japanese stuff, and had a US HQ in Secaucus NJ. While the TMK stuff was sold by lesser discount stores (Ames, Bradlees, Kmart, TG&Y, etc), they were a presence in audio as well, making some Phone/Cassette/Radio units also sold at discount stores under various store or other names. Their imports started in the 1960s, as promotions with airlines that introduced travel and routes to Tokyo via CONUS airports. Some magazine ads are still around with the "get this transistor all band radio free when you book a flight" kind of thing. While not mentioned by brand name, the radio is a Toyo or TMK radio.

Toyomenka along the way became a spin off of Toyota's electronics and raw materials arm. They originally were and arm of Sanyo.

Orion, like Clinton, NEC and Hitachi, sold CRTs to everyone. Even RCA used one in their little 5" BW radio/TV/Clock sets of the late 1970s. We had one in for service once - under the RCA label was the UL/import clearance label with the Orion name.

EDIT: Up until a few months ago, I had a similar TMK chassis. It was a dropped set, and broke the plastic surrounding the CRT face and dislodged the shadow mask. I salvaged a few parts with a soldering iron and tossed the chassis.

Wow.Thats some info I did not know about TMK. Unisonic sets used a Orion CRTs.I know my 3 inch set has one .I cant remember if the 2 inch set has.

It's a model 750C with a build date of April 1981.

Thanks.The 755 is the younger brother.I think I have a TMK VCR somewhere around here and some VCR manuals that were discarded from the shop years ago.I cant recall if they were any good or who make them for TMK.
