I am having an issue with Row 4 in the switch matrix.
I am still collecting facts and I will post on the general forum once I have all of the symptoms.
If I do not use the game for several days I get an error.
The game will boot ok. (Using 9.4CH Eprom)
You know there is going to be an issue if it prompts you to go into reports.
If it doesn't give you the prompt, all is fine.
If you leave it in attract it is fine.
If you go to start a game it spits out a ball then gives the (2) Danger warnings and goes into tilt.
Sometimes if you plunge the ball it will shoot it back to the out hole and give a second ball ( and tilt that one also) and other times it will not.
The error is always "the clock is broken".
If I use the game everyday. There is no issue.
If you go into test (again, please keep in mind I am still gathering facts)
(14) Plumb bob is closed
(24) Always closed is blinking
(94) 30 second is blinking.
You will hear the gumball VUK (74) shooting with nothing in it.
Usually, within 8 to 10 minutes of searching the tests, it will correct itself and all is well. There is no clock error and it functions fine. There is no tilt and it is fine. You can boot, reboot, and play a game(s) normally.
I am not going to use the game for a few days and do a full switch test to see/record condition of all switches in that row.
Then I am not going to use it for a few days and boot it with J212 disconnected.
Before I had this narrowed down, I believe it was still tilted with J212 disconnected. BUT, this was as I was trying to figure this out so I will not submit this as fact yet.
If no one has any insight to this, I will post as its own thread on the main forum.
