Entry level 19" Zenith color TV from 1984

Here's a set that someone gave me, years ago, and it worked; but, I was not impressed with the picture. The color demodulation seemed off and I solved that problem by jumping two pins on connector 2B7. At that point, the set had a good picture and i put it into storage.

Fast forward a few years, and the set I was using at the time (a 19" Thomson-era GE with a CTC136 chassis) popped it's flyback. At which time, I pulled out the Zenith and it now had a solid green raster with retrace lines, due to a leaky video output transistor. After replacing that part, the set was ready for service.

After a few months, the set developed an intermittent problem where the sync would go crazy and the picture would become severely overloaded (AGC issue). I fixed it by re-soldering everything in the AGC/IF area, and removing the IF/AGC IC from it's socket and soldering it to the chassis. Years ago, I learned my lesson with intermittent IC sockets, when I had a Curtis-Mathes drive me up the wall and it was a bad IC socket.

The set has been working for months now and so far, no problems.

This set uses a 9-181 signal module, a 9-186 horizontal sweep/HV module, and a small kick-start board.

The cart is one that I bought at a church rummage sale and I think it's like the cart that one could buy to go with these sets.
