The tab is actually on the top of the plug. The pic just shows it on the side.

The tv schematic shows the top 2 pins are 120v AC and bottom pins are 12v DC.

Isn't the tab at the bottom of the plug, to mate with the jack?:)
I think Pano means that the tab doesn't align with the spacings of the 2 sets of pins.
See below.
The wider-spaced pins are nearest the tab on the jack, but the plug appears to have the wider-spaced pins opposite the tab.
BTW I don't think I've ever seen that type of ps connection... 12VDC on a 2-prong AC plug.

Theres a space/slot at the top as well. My Guess is it could fit either way.
Im probably just gonna find and use a 120v AC cord and use that and use some
heatshrink to cover the bottom pins.

What I dont understand is if I used a 4 pin cord like the Sony, how does it know which voltage to use ? (12v or 120v)

My little Sears TV that was stolen used that plug. I made up a cord to run the set on 12v, so I could take it in my car and listen to football games driving around.

The 120v AC cord only had the two pins live that connected to the mains. Your 12v supply had the same connector but wired the other way. Just as Robcrx thought.

Thanks. yes I found the correct cord.
The AC goes to the narrow set of pins, the wide set must be for DC and are empty on this AC only cord.

It's made by Kawasaki! and the part number is KS-23
