Hog II Battery didn't help

Hello All,
I recently changed out the battery in my Hog II. The console was not keeping a show in memory, and It was a used desk, so I figured I would swap it out. It didn't help. The console still will not hold a show in memory.

Additionally, but most likely unrelated, there seems to be a video image problem with the left hand touchscreen. I can select palettes as well as see the backlight adjust when I adjust the contrast, but no information. When I swap screens the problem stays on the left. The working screen behaves like I describe, and the previously problematic screen now operates fine.

Any thoughts on either of these?
