  If your Suzohapp Cash Counters & Coin Sorters machine doesn't start and there's no display, here's what you can check: * **Mains cable:** Ensure the mains cable is properly connected and functional. * **Fuse:** Check the mains fuse at the socket, the fuse on the PSU (Power Supply Unit), and the PSU board connectors. * **+5V DC:** Verify the +5V DC voltage on CPU CN2, pin 1 to negative. If these checks don't resolve the issue, the PSU or CPU board may need to be exchanged.

  If the motor of your Suzohapp Cash Counters & Coin Sorters machine does not start, consider the following: * **+24V DC:** Check for +24V DC on CPU CN2, pin 8 to negative. * **Relay/Triac:** A defective relay or triac on the PSU board could be the cause. If so, exchange the board. * **Connection:** Inspect the CN2 connector for bad connections. * **Start Switch:** The start switch might be faulty; consider exchanging it or the CPU. * **Motor:** The motor itself could be defective and require replacement.
