Elmo K-100SM No Power

[Bobby Crabtree]

Hi, I am new to this forum. Hello.

I have a question. Searched the archive and could not find my answer. Hopefully I did not miss it.

I have an 8mm/ Super 8 Elmo K-100SM that has been modified by a seller on ebay to use for video transfer. Has LED "lamp" and other mods. I have had the projector for several years with no issues. I have asked this question to the seller, but has not been very helpful, and a little elusive.

I am getting no power to the projector at all. The power section of the projector appears unmodified. There is a line fuse that tests good with a meter. By the way, tried a different power cord and a different AC outlet. No change to problem. Is there possibly and interlock screw on the machine? I found a screw under the unit, but can't identify if it came from the unit, or another project of mine.

Anything else I can check? It is just dead in all positions of the front switch. The last time I used it, which was several months ago, there were no issues at all.

Any help would be appreciated.

Regards. Bobby

Hi Bobby,

I saw this and guessed "fuse!", but you've covered that.

Since you have a meter, if you feel qualified (-bearing in mind the shock hazards here), the thing to do is put the meter on AC volts, starting at where the line cord plugs into the machine and working inwards until you find out where the volts stop.

Smart things to have: work gloves, safety glasses and electrical experience if at all possible.

If I felt I couldn't probe safely by hand, I'd try to hook on with clip leads with the power off and then plug the machine in.

There should be a power transformer in there: I'm guessing you can learn a lot taking measurement on its terminals.

Thank you Steve, good idea. I will do that. I am comfortable doing that. I am figuring there is not too much to fail in the power circuit other than that transformer. Hopefully not that. Hopefully it is me doing something stupid.

Regards. Bobby
