I have a couple of these projectors sitting around, not a bad looking machine so I wouldn't mind testing them out. They are missing their power cords. Has anybody seen these types before?

See picture for back of projector - does not look like a very standard cord.

Hi,

maybe it's one of these connectors?

Thanks Joerg
Could be, I've found a similar one to the second one. The width of the connector is about 7mm on the projector and 5mm on the cord I found, so it actually can be held on to power up the projector but will not stay on. Of course I don't really want to do this.

Cheers

It may also well be the case that the earth/ground is carried on the outside of the original connector, touching the inside metal in the projector.

In which case even if you do jerry-rig it, you should also seek a path from the metal chassis to earth/ground.

You might try a standard (2 prong) ungrounded 120 V extension cord. Typically, there are ones with an elongated body with two plugs on opposite side of the plug and one at the end of the plug body. I have several myself. These look like just a regular 2 prong male AC plug usually found on any US or Canadian wall plug.

May be wrong but you may want to give it whirl.

Thanks Rick , that has crossed my mind also.
I just have yet to find one that has the plug on the end though.
I'll keep looking.
Cheers

Yeah Terry. I can understand the difficulty. Most of the cords now have the plugs on both sides of the body. Any that don't are the UL saftey cords that have molded tabs to prevent plugging in a grounded plug to a two wire extension cord. Might be able to modify the body (nip & tuck it) to fit. otherwise, may have to just solder a cord in to the plug wires and run it out the back someplace.
Kind of like this:  -

If all else fails the best thing you can do is take it apart and swap the inlet to a modern style one. I've seen this done on a couple of machines and if done well it doesn't even look very different.

That case ground is there to blow the fuse if something live touches chassis. Without that there's nothing between you and a trip to the Great Screening Room in the Sky if something goes wrong.

All I ask is a wide screen and a projector to light her by...
