The same issues I am having is that the segments are not working properly. I am getting 7.83 VDC out of the adapter and on the 2 pins on the PCB. The one picture has the timer running and I scored one puck on the home side and you can see it doesn't show a 1. You can see when 10 minutes is selected, you can't read 10 minutes, when 20 is selected, that reads ok, and when 30 is selected, again, you can't read it. I tried removing those 2 transistors again and then the whole board got wacky, only the right zero would light up for both home and visitor. After about 1-2 minutes, the G segment starts to flicker a bit, but it is definitely hard to read the scores. Also the countdown is fast, it actually takes about 6 seconds to count down 10 seconds on the display. I couldn't read anything on the old speaker and I had an 8ohm 2 watt speaker from another electrical item so I tried that and that is causing the other transistor(s) to get hot. I noticed 1 or 2 other transistors getting really hot until I unplug the speaker. Now all the segments seem to light up some what dimly and the E, D G segments seems to always stay lit, but not full on bright. I replaced the speaker with on from another unit and trying to figure out the segments from an old thread from another site, I replaced the transistors for those 2 segments. When I first got it the E & D segments were not working nor the speaker. I picked up a Classic Sport Air Hockey table and the scoreboard isn't working.
