Ultimaker 2 Shut down mid-print w/power supply still on

While printing at 260C the machine suddenly shut down and I thought it was a fuse in the plug source, but when checked there was still power at the power supply and the DC plug to printer. Any suggestions what to check next? Machine is all black no power up.

Update - checked power supply and found 52.5 V? Examined board no burned areas.

52.5V DC coming out of the power cable when it's not plugged into the printer?

 

If so then I'd say the computer is fried inside the power brick and you should get another power brick.  Or unplug it from the wall for a good 12 hours (it takes an amazingly long time for that LED to go dark) or into the LED goes out such that the computer in the brick reboots.

Hi,

Correction - meter was set to A/C after checking in D/C mode voltage is correct, 24.1V.

Today disassembled the hot end and all looks OK no burned wires inside.
