484 model works but no display for selections/playing

[christyh]

I've been digging around and I'm just not finding a lot of guidance on our specific problem.  The 484 pc logic board tests out ok, playing the records in the correct choice and order, everything sounds great, but I don't seem to get responses from the hit tracker, profit setter, or the keys.  We pulled and cleaned the keys, but the reset button flashes all the time, and I get no numbers up on any place you should see numbers.  I do get dashes on the hit tracker, but nothing changes no matter what we do.  We've got the correct 9.6 v out of the pot, we've checked all fuses. . . found one 1/2 amp fuse blown on the board in the back, doesn't seem to make a difference when replaced, checked connectors, etc, wondering if someone can give guidance on if there are any obvious things to check.  We have the repair guide, but it doesn't address lack of display. .. flashing reset button, etc.  Thanks for any suggestions!!!

The normal user interface is via the profit setter. If the 9.6V is good, it might be that the profit setter display driver has failed if you have no display. For home use, the hit tracker is not really required (in my opinion!). The hit tracker uses the same display driver so you could try that one in the profit setter.
