THANK YOU SO MUCH

Might have found the problem with monitor?

Thanks for the reply.  The fuse test okay and I am getting power to the monitor.  I will check the other things and post.

Here are the pictures.

Okay, I found a wiring problem and fixed it.  Now I can hear the game playing.  But I do not see video.  Any suggestions.

AC power is fine.  Now looking at DC power.

I watched the video posted and read the instructions posted.  I now have the AC power working (at least I have power to the Frogger marquee).  I tested each set of wires that is for AC power and I think they are all okay.  Someone before me had cut each of the AC lines and taped them back together (with duct-tape). 

I did a test and I think I am getting 5v to the main board but I am still a little unsure if I am getting the correct power to the monitor and still no sound?  Not sure what it needs.

Thanks everyone.  I will read this weekend and make sure I understand what I am measuring.  Everything posted has been a big help.  Thanks for your time and help with my questions.

To make sure I am asking guestions about the right parts, can someone tell me what these 3 parts are called?

Please

First thanks for the reply.

When I test the 5v, I get almost 5v.  When I test the 100v, I only get about 5v. I have not changed any wires.  From top to bottom on the power supply there is a wire connected to the 5v spot, then one connected to the GND, none on the ones labled NC, and then there is one wire on each of the ones labled AC 100v. I can't figure out why I don't get 100v on the ones labled 100v??

Okay, new to trying to repair an arcade machine.  I have a Frogger upright (sega-gremlin) 1980's machine.  I can't figure out what is wrong with the power.  When I plug it in the monitor makes a sound for about 1 second but nothing else.  I changed the fuses and still no luck.  I think I have a bad power supply.  I tested all the power cords to the different parts.  Some of the little power plugs get power and some do not. Any suggestions as to what kind of new power supply I could get?  I have included a picture of the current power supply.

Thanks for any help.
