Quoted from bstmstr:
Thanks Chrisnack. It's totally the batteries - display tests work great. I just haven't gotten around to attaching a new battery (gotta order the battery mount).
Only thing I have left on this pin is to fix some cupped lights. Looks like I have to fill them with clear coat then sand them down. But I will wait until summer to get into that. Other than that, the machine works great!
I have a cupped inserts on mine as well, haven't figured out the best way to deal with them, there are a lot of "opinions" on the right way to do it, and haven't decided what's the best way yet
My Joker Poker, i have a new CPR playfield so that's easy. My Sinbad, i have a spare playfield i think i'm just going to have the entire thing coated... but for the remaining ones... not sure if i want to try to filling the inserts.. sanding with new decals.. or what... keep us posted on what you decide and how it goes!
