Accidently caused a spark under bed where power cable is soldered onto bed.  Now printer will no longer power up or show any signs of life.  I have tried the following, but still no luck.  I have checked and tested the power cord, replaced fuse, replaced power supply (with switch at 115v), unplugged bed at Motherboard, unplugged LCD unit at MB.  After each step above I would test for power, but still nothing.  Fuse on MB looks OK, but not replaced.

HELP!!!  I am lost what to test next, but maybe the MB.  Is there any way to test the MB easily??  Requesting any ideas or suggestions.  The original MB is a V4.2.2 and I have not upgraded the firmware since I received it in December of 2020.  If replacing MB do I replace with a V4.2.2 or the newer V4.2.7.

Thanks   John

So could the firmware on the printer get corrupted. It just seems like l should see some type of response when the power switch is flipped on.

 

UPDATE. Finally replaced MB and up and running.  Replaced with the 4.2.7 mb.
