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.

I have no idea how to find this proper cord ! You think Sanyo would have old stock ? :scratch2: |

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. |

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.

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. :sigh: |
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.

This guy has all kinds of cords. Might be able to help by sending him your pictures with dimensions pin to pin.

Not the easiest site to navigate! I guess if I had to do it I'd call and ask how I could email him some pictures.

Anyone can help me with this ?

Hi guys,
do you think this sony cord will work ? http://www.ebay.com/itm/Original-SON...item589f2e291c |
|
Couldn't you just make one?

Use an ohmeter to check for continuity from the plug to each of the four holes. The two that have continuity are the AC connections.

The tv schematic shows the top 2 pins are 120v AC and bottom pins are 12v DC. (SEE ATTACHMENT)
|
I believe the DC pins are used to charge a battery using the 120Vac coming in from the wall. You just need to make a cable with four pins that fit the socket on the television. I could do it but will cost as much as the one you found! Best to make your own!

Okay, now that I see the whole set from your post at A.R.F. I realize which set this is and I can at least offer you a picture of the cord and the part number.
Also it appears 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, that may help in your search. |
Great thanks !
Do you recognise the TV at 24 seconds of this youtube clip ? http://www.youtube.com/watch?v=uWNVbFArFDQ It's the "Titanic" set, that is, it's the same model Old Rose is watching at the beginning of the 1997 Movie. |
That's where I got that picture I just posted!
Did you get my PM about the cord? |
