To make a long story short, I purchased an NBA Jam arcade today and had to use a friends truck to move it. The machine was covered with a tarp, however during the move it began to rain and some water managed to get inside.

Upon arrival to my house, I opened the back and didn't see any water at first glance. So...we fired it on and it played flawlessly for about 3-4 minutes, then the screen went black. Music and sounds still worked perfect, just no picture.

After closer examination, I realized there was some water around the wires coming from the monitor. So a few questions.

1) Could this small amount of water kill the monitor entirely?

2) Could the water have caused a short that just requires time to dry out? If so, how long should I wait before plugging it back in and turning it on?

I'm clearly not an expert on these, but I know a few things. It just seems odd that the monitor worked perfectly for about 3-4 mins before turning off.

Any advice is welcome, I just hope I don't need to buy a new monitor.
 
Welcome to the Arcade collecting world. There is a monitor section here. I would try a thread there as well. The monitor should have a fuse or two. Check to see if any of them have blown. Check them with a DMM to make sure, visually is not good enough. Do you have neck glow? The monitor should dry out completely before attempting again. It is also a good idea to take some pictures so we can tell what type of monitor you have.
 
Thanks for the help Tom. I'll get a couple pics posted soon. It is a newer monitor, guy I bought from said he replaced it in 2002.
 
I would blow the cab out with compressed air to get any visual moisture out of there and let it sit in a warm spot over night to dry then go at it with a DMM to see what you find. For further piece of mind take the monitor out and blow it off with compressed air then youll have more room to test with as far as checking fuses and shorts but you wont be able to test voltage like that. Whatever you do dont power it back up till youre sure the moisture is gone and youre fuses are atleast good.
 
Here are some pics. I put a DMM on all the visible fuses and those checked out fine. Now I'm not sure exactly what "neck glow" is, so I can't really diagnose that. What should I check other than fuses? Also, there are some things on the monitor board that could possibly be hiding fuses but I didn't want to take the board out and apart to check. Any tips?

Neck glow is the tube lighting up at its base. It is usually dim, but visible in regular light. Check to see if the monitor is getting power. You may have some fuses at the bottom of the cab as well.
 
I'm not seeing any glow in the tube when it's turned on. I presume this is not a good thing. Also, I checked the fuses at the bottom of the cab and those were fine. What should I do about the tube?
