Get a good quality manual, check fuses, check power for display at the
display. If the machine works otherwise that is the starting point.

Did display work until recently or did it never work for you?

As John says, the manual will help you but try and get one that includes the large fold-out schematic, as originally supplied by Rock-Ola. At a guess, I would say the problem is likely to be the display controller chip in the profit setter. The good news is that there are two of these chips used in the hit tracker, which in home use is usually redundant - so you can do a swap. I bought a replacement chip maybe a couple of years ago, so they were still available then, although not particularly cheap!

Norman.
