Panasonic TR-535

Another novelty from Panasonic, this TR-535 black-and-white portable is definitely one of the most unique sets in my collection. As the pictures show, the television actually pops up out of the cabinet, almost like a jack-in-the-box toy. It is incredibly complex both inside and out, with many different circuit boards spread out across the chassis all interconnected with dozens of wires. Interestingly, the TV portion is lifted up during disassembly, somewhat like the hood of a car or even the Commodore PET line of personal computers.

My set works and displays an acceptable picture, however the controls need cleaning as they're quite flakey and need constant tweaking before they adjust properly. The VHF tuner is quite weak with some channels only displaying a blank raster, which I suspect is one or more bad capacitors in the tuner circuit. More diagnosis is needed; however, as of the writing of this page (1/5/2020) I have not gotten around to troubleshooting it yet. I will update this page when I fix the set completely!

Misc. Notes:

- Service information for this TV is found in Sams PhotoFact set # 1569, folder 2.

- This set is the oldest miniature portable TV currently in my collection.

- The dial cord for the radio dial is a bit loose and tends to slip, however I can still tune the radio just fine. I will look into tightening and re-aligning it in the future.
