I need some direction on my Frogger.

The game will play blind and nothing on the monitor.

The AC and DC voltages measure about 1/2 of what they should be,

The power cord goes into this box first and the AC measure about 64 vac coming out.

inside the box:

Also the voltages here are
#1: 2.5 vdc
#3: 64 vac

I did not see a way to adjust this power supply, but it seems like the problem is before the power even reaches this point.

Fuses are OK and the power cord continunity is ok also.

ideas?

If your reading the voltage at the interlock switch, that's why you're reading about 60 volts. The interlock switch has two wires going in one side, and two coming out the other side. Both will give you 60 volts when referenced to ground, and 120 volts when added together.

If your voltage was really 64 volts, then your game wouldn't play blind.

Sounds as if you have a dead monitor. Take this to the monitor section....
 
Steve, Do you have another monitor you can try in it? If not I might. I have a few Power supplies laying around too:) What kind of monitor is it? I might have a cap kit.
 
If its the Nanao then you can pretty much count on the flyback being blown. I am working with a company that makes replacements..but its going to be another three weeks before I have an answer. If you have a spare monitor try swapping.
 
It's an Electrohiome G07.

Just found that the F901 is blown.
(The G07 Flowchart suggests a bad X01 transistor or a bad flyback.)
But it's a short fuse with leads coming out of it. Soldered
directly to the circuit board. Are this the 20mm GMP type of fuses?
Looks like Bob Roberts has those.
For some reason I know my local RS will not have any fuses like that.

You you just replace the fuse and see if it works? Or would you go ahead
and replace the fuse and the flyback at the same time?

Do a cap kit on it and also have Bob include the fuses.
 
I have a few G07 cap kits, I can sell you one at cost. Not sure I might have that fuse to:) I also have a rebuilt G07 chassis. new caps, flyback, width coil.
