damn, 54 bucks !

[mstaton]

did not look at the price but you can search for a Sony cord on the internet. Probably a better chance to find a Sony than Sanyo cord

Not so fast ! 2 pins are for AC , other 2 are +- 12v
Wrong cord & you may see fireworks.
A TV belching sparks & smoke is fun IF its what you want !

good luck

That cable is 2 pins in with 4 pins out - so you have 2 pairs of ac going into the TV. Do a continuity test on the 4 pins on the TV - 1 set of 2 pins should be connected together, and the other set of 2 pins should also be connected together - now you can just connect a standard 2 pin AC cord to the proper pair and the TV will work properly.

First of all, the cord shown in post #1, is from an RCA or an RCA built GE.
The cord has four pins on the connector end. Two are used for 120 VAC. Another pair are used for 12 VDC. The DC cord is simular but has the cigarette lighter plug on it and using a different set of pins on the connector end.

OK - very unusual that it is wired that way.

You should be able to identify the 2 pins that are for the AC circuit, and still use a standard 2 pin AC cord to power the TV.

Please include the model # of the set. The pictures in post #1 show a different set.
If we have the proper model number, maybe there is a Sams folder on it, so the pin out can be traced.

TV is Sears and Simpsons made by Sanyo in Japan Model #14062.

I don't see anything listed in Sams under that number.
They never had much on Canadian products, unless it was an item that was sold here.
I don't know if Sears still has stores in Canada. They closed down a lot of stores in the states.

Just look up 1978 sanyo portable tv. Im sure they use the same plugs.

I can't really see from the pictures but some of these sets have a switch inside the receptacle to switch to 12 volts or AC. If it does, be careful as the wrong setting can also fry the set.
