Hi All,
Thought I would post this here for general information regarding a problem I saw on my Data East Star Wars Flipper. This can happen on any Data East Solid state flipper that does NOT have an EOS switch. I think the EOS switch was re-introduced in later models. Anyway......
I noticed during play the flipper was easily knocked down by the ball as it hit it thus resulting in a ball drain. Also, on one occasion the flippers would flip up and down on their own while keeping the flipper button pressed.
The fault was traced to a low voltage coming into the flipper controller board. What should have been 16v AC across the two 8v AC inputs (grey and gry-grn wires or F2 and F4) on the board was less than 5v AC. This was also present on the Power Supply Board that generates the 5v DC so goodness knows how I was getting a reliable 5v to the other boards. I traced the fault to the 2 pin connector (3 pin housing but only 2 pins used) on the floor of the main cabinet the takes the 8V AC from the transformer and splits it to the flipper controller board and the Power supply board in the head. There is another connector coming directly from the Transformer too that will need checking.
Two wires feed into each terminal on the connector and those wires had come away from the terminal pin itself - The grey pair in my case. Pulling on the wires confirmed this so I had to strip them back, cut open the side of the connector and re-solder them both onto the back of the pin.
All working fine now.
