Back in 2000 I pieced back together a MACH 3 upright laser game. I installed a new Happ 19" monitor which had a great picture and has never given me a problem till now. It has very low hours, mainly gets used twice a year for 8 hours each time so no more than 16 hours a year. The last party I had (Christmas Eve) I went out in the game room to turn everything off and noticed my MACH 3 was playing blind so I turned it off and never looked into it till now. Everything on the monitor still looks new, nothing burnt or loose so the first thing I checked was the power and I have AC on the plug so it's getting AC power. Next I checked the 2 fuses on the chasses and found F502 a 1amp 250volt fuse had blown. I looked and don't have a 1 amp fuse so I am going to try and find one local. In the mean time I thought I would ask if anyone has had any experience with this monitor and might know why the fuse blew. I know fuses usually don't blow for no reason and don't have hi hopes just replacing it will fix the problem. The board has K1-2-VO and SUM on it. I did a search and found a post from Ken Layton which posted a link to this manual and it appears to be a match.

Anyone have a flow chart for this one.
Here's some pictures of the monitor.
