Geeetech A20M 24V in the structure

[juanter]

Only a few days ago I have the Geeetech A20M printer.
I have detected, after taking a spark, that there are 24V between the chassis of the fuser and the rest of the chassis of the Geeetech A20M Printer.

Also damaged the 10A fuse of the GT2560 board

Someone knows how to fix it?

Hi, You can

1. After replacing the fuse on the motherboard, check if the three lights on your motherboard are properly lit;
               
2. Measure the output voltage of the power supply.
