No power after initial heat up..

After going through all calibrations fine, the printer went into heat up then shutdown. I have the new black power supply that is supposed to auto switch to 110/220. I tested the fuse with a multimeter and it is fine. LED on power supply is not lit. I also disconnected all wire from the power supply and still nothing. Thanks for the help...

For a new printer with power supply issues you are safest to go directly to Prusa support.

Push the plug into the power unit REALLY hard

Sometimes it is just the plug is not seated into the socket

Wish it was just the plug...

I tried that, tested the cord and also used same to power a monitor and all  showed fine.

I contacted Prusa and they are sending a new power supply, but they are not sure of the cause or why fuse didn't fail first.
