Just got my very own HH. Worked perfectly when I got it from the seller. Disconnected it and got it home. Everything worked briefly. In the middle of my first game the ball got stuck in the middle VUK on the left and the score went blank. Numerous resets and I can’t get the scores to show at all. The game doesn’t even boot up. GI turns on but no scores show at all. Any ideas where to start looking?
