EasyCoder PX4i and PX6 Service Manual
Description:
The power LED does not become lit when the power is switched on.
Possible Causes and Suggested Remedies:
• Blown fuse.
- First check that the fault is not caused by an interruption of the 90-
265 VAC input voltage, a faulty power cord, or a disconnected power
cord.
- Inspect the fuse F70. If the fuse has blown and you are positively sure
that the fuse has blown because of a short-circuit of your own doing,
you can cut off the legs of the fuse and solder a new fuse in its place.
If the fuses blows again, replace the CPU board.
