Tajima TEHX-C1501 Spare Circuit boards

Hi,

After 9 years of no issues with my TEHX-C1501. Switched on the machine and detected a slight burning smell. Machine runs with no X Axis, while Y is working fine. No movement with L/Right frame travel keys either. Only a slight hum for a few seconds. I ordered the pulse motor, on its way but thought that it may be with one of the circuit boards. Not sure if X/Y driver board or another. Some advice would be much appreciated and looking for spare boards.

Thanks.
