Just a quick update. I've now installed my new cheap chinese main board and my ultimaker 2 (now a 2 plus with the upgrade kit) is currently working away on its first print...fingers crossed it gets to the end........?!?!?!
Still not sure what happened to my original main board but I guess these thing happen from time to time.

Torgeir...thanks for the suggestion, unfortunately unplugging the 5V fan made no difference and there is no voltage at those 2 pins
gr5...Having done a few more checks it seems the voltage ranges from 28 volts when I switch the brick on, which then settles to about 26.5. Not sure if that is normal or not for these power bricks. However I checked the voltage regulator part number that Torgeir mentioned and it's max input is 46 volts.
In the mean time I've ordered one of these....
....but I would like to try and figure out whats gone wrong before I plug my new main board in!
Thanks for your help guys

Thanks for your quick replies guys
)Definately getting a voltage on the board where the power connector is soldered to the board. Its actually measuring 28 volts, but I guess this is within the normal parameters of the power brick? I had the power brick turned off for a good 12 hours as I'd read about them sometimes needing a rest lol.
Also measured 28 volts at TP76 and TP77 with the power switch ON, and no volts with the power switch OFF.
From what I've read previously on here I should be getting 5 volts between TP16 and TP24 but I get nothing, which is leading me to believe its the regulator.
Any ideas where the regulator is and if its an easy fix? I'm reasonable ok with a soldering iron as long as its not too fiddly!
Many thanks

Hi Guys
I wonder if anyone can help me troubleshoot a problem? I have a UM2 which I've owned for a few years with no problems. In the last few days I fitted the extrusion upgrade kit. All went well with the upgrade and I did 2 small prints which came out great. I start it on a third print, come back an hour later to find the printer has died mid print...screen off, lights off, no signs of life! This was yestarday and it still wont switch on!
Things I've checked.....
Power brick blue light is on.
24v is being supplied to the main circuit board
No LEDs light up on the board.
No obvious broken or damaged wires
All connecters on the main board are plugged in where they should be.
Ive checked the voltage between TP24 and TP16 on the main board (which I understand should be 5V), but I get nothing.
The main board version is 2.1.1
Any Ideas if there is anything else I can check or am I looking at a new main board?
Many Thanks
Mike
