Wells 9200 dim screen and vertical size issue

[ericgla]

I just picked up a 2003 Golden Tee machine on Craigslist for $50!  The only bad news is that it has the dreaded Wells 9200 digital monitor.  The monitor is working, but is dim has the top part of the screen is collapsing on itself.  I've included a screenshot, and was hoping someone could help identify the problem.

Also, where is the best place to order a cap kit for this monitor?  I used to get all my cap kits from Bob Roberts years ago, but it looks like he doesn't have a kit for the 9200.
