The monitor in my Mario Bros cab has been acting up. I haven't done anything to it as it worked/looked great when I got the game. Anyways, normally it looks great. Every so often it does one of two things.

1)The picture gets really light all over like the brightness turned way up for a flash or even up to a few seconds then it goes back to normal.

2)The greens drop out of the picture for a few seconds up to like 30 seconds but then it returns to normal.

There doesn't seem to be any rhyme or reason as to when this occurs. Sometimes it's only minutes after I've turned the game on, sometimes longer. I left it on for a couple hours while I was working on other stuff in the gameroom and didn't see anything more happen. Bumping the game while one of these two issues is happening didn't affect anything.

I am for sure going to do a cap kit. From other threads I've seen am I right in thinking a new flyback might be necessary for the brightness issue? Just trying to get some ideas before I pull the monitor.
