Follow the procedure step by step to correctly diagnose the problem. Take particular care with the
checks highlighted by circled numbers, which are described in detail below:
(1) Check the LED D41 (green) of the display board, is correctly lit on.
(2) Start exercising in “Quick-Start” mode and check if the resistance change and a beep sound is
being produced when you click on the touch sensor buttons.
(3) Place the tester probes across pins 3 and 1 of CN4 connectors on the Brake board The
measured value should be approximately 220 VAC or 110 VAC depending on the mains
voltage.
(4) Slightly lift up the fastons on the machine power entry module. Place the tester probes across
the live and neutral pins on the same connector. The measured value should be approximately
220 VAC or 110 VAC depending on the mains voltage.
(5) Using a tester, check that all the output voltages on connector CN1 of the Brake board. The
measured value should be:
• +12 Vdc between pins 6-2;
• +5 Vdc between pins 7-3.
(6) As for step (5) but on patch connectors 1 and 3 of CU195 cable.
(7) Place the tester probes across pins 1 and 2 of J1 connectors on the Digital TV board. The
measured value should be +5Vdc.
(8) Place the tester probes across pins 2 and 6 of CN20 connectors on the CPU board. The
measured value should be +12Vdc.
If you replace Display board/Brake board, check that its SW version is updated, otherwise
install the last version.
The TV and RADIO channels is located in the Digital TV in the CPU Board and must
necessarily be present. This means that when even one of the two boards will be replaced,
should be re-stored channels through search or transferring from another machine via TGS
key or cable transfer.
