I’m new to vintage slot machines. Received an S2000 Palio Pix (SB000477) as a gift. Machine was working well but now it won’t boot up. Stops initialization with message “Waiting for video display”. Starts with one green and 2 amber lights on CPU but when it stops the initialization there are no lights, no buttons active, video screen never comes on.
All I have done in the past was place a fresh battery on the board and it worked well for a time after this. Machine is set up coinless with a printer and bill validator. It does not have TITO but I was hoping to add this later. All connections seem tight and proper with all chips well seated. Next steps in trouble shooting? Thanks in advance.
