I picked up a LAI Stacker machine last week, red version, and need help with a few issues I'm having with it as redemption machines are not my strong point.
1. Weird buzzing/display issue every minute or so.
In attract mode, things will be going normally, then every minute or so for 5-6 seconds, the speaker will make some very quiet buzzing noises, and the main stacker display as well as the credit/countdown display will show gibberish (random blocks/lines) as this buzzing is happening, everything will then go back to normal.
2. Cannot get into test mode.
Press the test switch behind coin-door....nothing.
Manually connect wires for test switch momentarily....nothing.
Use jumper wires to short out pins for test switch at the board...nothing.
Service switch still works ok.
3. Error 5.
Getting error 5 about the prize sensor. Have lined up the opto/led boards and the error went away. However when a prize goes to dispense, the coil turns 2-3 times then error 5 reappears before the prize drops. Turn the game off and on, and no errors until a prize tries to dispense again. Is this still a matter of alignment or a bad LED or ?
I can probably get a video of these issues put up when I get home from work.
Thanks for any help in advance!
