This way, you will also know if the contact between fuse and fuseholder is OK.

You can get false positives checking fuses still in the circuit.

Very rare. That's also why I use Ohms and not the continuity setting.

My experience has been different. It's not common but it can happen and it takes two seconds to pull a fuse. It happens a lot more in pinball machines I've noticed with so many more fuses and more fuses on PCBs. Here is a decent discussion on the idea.
I'm not familiar with this monitor... could he be missing a signal PCB and that's where the game signals would go?

Is that correct?
You need to check for AC power at the connector I pointed at with the red arrow.
That is what feeds the monitor power.
If the power is good there, then you'll have to move into the monitor repair side of things.
(and of course check for any fuses in the bottom of the cabinet as well if it's not good)

The connectors circled in green go directly to the connector in red.
I checked the AC power at the connector with the red arrow and I'm getting a reading of 1.048. Does that seem right? I also check all the fuses at the power supply and they are all good.

Make sure your multimeter is set to AC Voltage. The reading you say was probably either Resistance or DC Voltage.

Oops! It was on DC...now it reads 120.
