Quasar - Works in a drawer... or box... or pile... or someplace else
 
Checking out a couple recently acquired TVs, and this Motorola/Quasar set is kind of interesting. Solid state, but VERY heavy. Opening it up to have a look, and surprised to find that the power supply panel board is missing. An unusual take on "works in a drawer", I suppose. The works could very well be in a drawer, or any number of other places that aren't in this TV. I'm always wary of sets that come to me with the screws missing...

In any event, neat set - maybe the missing part will turn up somewhere in the same place the TV did, it's possible. I'll be back there at some point in the not too distant future.

It looks like a table model that had a "JA" panel in it.
It was one of the first sets to use a switch mode power supply. A bit of a high failure rate part.

Dont remember if the 19" used the JA. First one I saw was a real head
scratcher. Kinda figured out what it did but the boss said just change
the GD thing. Glad I did.

I looked at the pictures again! The set might be a pre-JA model. 1972 production.
Some of the nineteens used another type of power supply board that used two SCR's and two rectifier diodes in some kind of a bridge configuration, plus several other parts. I don't remember it very well, as I just replaced it as well.
No matter what board it uses, the O/P is SOL unless the board is found. :sigh:
