First double check the model ##. Canadian set are different sometimes.
Then post it & I can look it up. Probably a jumper involved in the
plug also.

I had a similar Pantysonic...many years ago I lent it to a friend who was temporarily bedridden. Her stupid cat knocked it off on to the floor and ruined it.

Dont blame the poor cat ! If I were bed ridden there would only be
one thing I would rather have than a cat ( related) !

Those are very dependable little sets. We used one on the workbench for years as a monitor for VCR repair. It was turned on from 8:00 AM until 5:00 PM six days a week for about 20 years, and always produced a quality picture. When I closed up the shop, I gave it to a friend who ran it in his garage for many more years. I wouldn't doubt it still works.

Ya, I'm dying to see if it works or not, I just don't want to blow it up putting power to the wrong pins.

I ordered the photofact for it, hopefully Sams can dig it out and scan it quickly!

I figured the connector out:



This set produces a great little picture... nice color and super sharp. I don't know how many hours were on this set... at least a few since the lettering around the volume knob is worn off.

Hi You have a nice model and the picture is very , however, I see poorly made welds, where I put red arrows . May be i'm wrong but the welds are not like the others .

Just got out the Sams. It also shows a jumper from +12vdc to -12VDC pins.

OEM cable is
AC cord TSX1174
DC cord TSX1302

In my diagram, which pins would that be? Is that jumper part of the 120v cord?

I might touch up those solder joints in the future, but for now the set seems to play perfectly.
