Any power problems or storms lately?

 

Customer: replied 6 years ago.
possibly, its been more than a month since it wasn't working. It is not on a surge bar or anything. is there an internal "fuse" or something? I'm a auto mechanic so not scared to open it up myself for something fairly simple.
Expert:  Tim Nolan replied 6 years ago.

There is a fuse, if you take the back off and follow the power cord to where it plugs in, right near that will be the AC fuse.

 

Do you have a meter to check it with?

What should it be? I just have an automotive style DVOM, but it should work. I usually only play with 12-24v stuff. I actually need to do some actual work for awhile, is it Ok if I reply in a few hours?
Expert:  Tim Nolan replied 6 years ago.

Right now we are looking for a 5V standby

 

Customer: replied 6 years ago.
no 5v on any of the connectors, using and existing ground, pushing power button does not make any change
Expert:  Tim Nolan replied 6 years ago.

What do you mean by existing ground?

Customer: replied 6 years ago.
A screw with a wire going to it from the power supply board. into the meatal case
Expert:  Tim Nolan replied 6 years ago.

Ok that should be good, any bad capacitors on that board?

Customer: replied 6 years ago.

Nothing looks burnt or overheated if that's what you mean, after that, your going over my pay grade. is it worth going any further, replace the power supply if i could even find one???

 

Expert:  Tim Nolan replied 6 years ago.

hmm...Ok how about this, can you get me a picture of the power supply? (if you can post a picture, please click the icon above where you are typing with the green tree on it. This will allow you to upload a picture)
