UM2 DEAD No 5v on motherboard

[AEON5 0]

Hello

Today my UM2 stopped printing and is totally dead.

I checked this topic:

https://community.ultimaker.com/topic/17152-um2-is-dead-after-short-circuit/?page=2

and checked the 24v & 5v. 24 v is ok but no 5v (or 3.3v). No lights are burning on the motherboard.

Is the motherboard dead? Or is there an other solution?

Thanks

You need an electronics expert who can read schematics.  Personally I would probably just buy another.  But some other things to try: check for hot components.  If a part is shorting the 5v to ground it will be quite hot.  an infrared camera can help.  Or just your fingers.

 

Otherwise it's probably the voltage regulator.  That's the component that lowers the 12V to 5V.  Do you have a copy of the schematic?

Thanks for the reply gr5 & the schematic! I will check for hot components later today.
