Wow, that game has one very strange design! There are 5 DIP switches that will kill it if in the wrong position (or not making contact in "on" position) AND they specify +5 has to be between +5 and +5.25 for it to run right. Looks like most of this was done to make it easier to troubleshoot (yeah, right). This looks very similar to the Bally/Stern pinball machine CPU boards in the reset circuit, right down to the 3.6 volt battery. And it also has the "blinking LED" self test like a pinball. If worst comes to worst I do have a suggestion of who could fix them (Eldorado Games). On Thu, Mar 21, 2013 at 7:18 PM, John Robertson <jrr@flippers.com> wrote:

Anyone here fix Berzerk/Frenzy boards and is possibly looking for a repair job? Have a fellow with a Frenzy that has locked up screen, however the 5VDC voltage sounded low so I am getting him to work on that first. If, however, is it the board(s) is anyone interested in taking over? I don't have a fixture setup for this game, nor known-to-be-good boards to compare.

Alex @ Electron Forge doesn't do these either.
