Been working on a MH and finally brought her home last night. Worked Till late and again this morning and had her nearly 100% working. Thought I’d hit a home run.
Then I took a lunch break and left her powered on.
When I came back half hour later the displays are out and game will not boot up
I’ve pulled and replaced all 8 fuses (6 on the Rectifier board. One on the SDB and one under the playfield.)
The small one on the SDB was empty and one end cap was loose. (it’s a 3/16A. And it’s a 1” long fuse. So I only have a 5A in that size. I’ve put that in just to try to get it working again)
When I power her up I get the 7 total flashes on the cpu board and the small relay cube in the SDB clicks. Then nothing No music no start / boot up.
It was playing All drop targets and saucer working All scoring Able to use the diagnostic switch and got just about all working. Now nuttin
Any suggestions or some tech advice on resolving this one?
