Hey guys,
I just bought my first pinball machine. It is a Robocop. I got a good deal but it is in need of some repairs. The cabinet is in great shape but the thing does not work. Burning fuses F1 and F2 on the Power Supply Board. The Digital Display fuse (F3) was burned as well. Lights work on the playfield.
Here are the problems:
Cannot get a game to start
Makes lots of noise from the speaker under the cabinet - loud humming and garbled noise
No digital display
-------Update : I replaced the bridge rectifyer. I tested it and it was shorted. The game started working. Display was not working so I rebuilt the power supply. Now the game is great! It is working fine! Thanks for the help!!!
At this point, I have already found a burned transistor - TR2. I have been told to replace the components in that circuit, i.e., C4,C2,C3. Here is a pic:
So, here is my question:
DO any of you have a digital version of the Schematic for this game? Otherwise, where is the best place to get one?
Any insight into the burning fuses? -
-------Update: One of you was nice enough to send that. Thanks for the help!------
