Have you checked your fuses to see if any of them are blown?

SOLVED= 7.5A fuse was in fact blown, it has been replaced and everything is back to normal. Thank you for the responses!

My apologies on the duplicate post, I checked the 7.5A fuse on top it looks like it’s reading 12v through it however the 1A fuse next to it is not receiving any voltage, however the fans are getting the 12v to them when checked with multimeter.

PSU is a 12v

I recently hooked up a new board cooling fan to an always on connection the fan works fine, however shortly after I was getting some messages on my paneldue that something was not getting enough power can't really remember exactly what it said. I turned off printer checked terminal connection and turned back on and now the opposite side of the board where usb and wifi module seem to not be getting power from the mains power checked with mutlimeter. NO wifi on, no paneldue on, no 5v or 3.3v light on, just blue VIN light. Only when I plug into to usb from computer can I get those peripherals to work. However even when I try to move motors they will not move...could this be a fuse issue? the always on fans spin and I can still heat the bed, thermistors are recording data.

Update: I have been looking at the board and it looks like its actually not getting any of the 12v from power in across the board hence no 5v from VIN the only reason my bed heater works is because it is connected straight to PSU. When using multimeter on the power in block it reads 12v its just not distributing across the board, to motors or the E0 heat.

Is this board dead?
