HELP US Chinese Laser LXJ 1390

Post by Harrihau »

HELP US
We have Chinese Laser LXJ1290 Engraving Machine/Laser Cutter, with Leetro MPC6585.
In the middle of the surgery, the machine went out suddenly.
The control panel will not power (panel is dark) and the computer can not connect to Laser. ( Communication failure)
The transformer works, because it gives 5VDC and 24VDC.
We changed the new motherboard and the PAD 04 control panel, but the problem is still the same.
Can enyone tell us, what is a problem on our device??
