Hello,
So i have a Ultimaker 2+ since 2015 and some weeks ago i started a normal print with 3/4h and after 1h i came to the machine and the machine was tuned off.
I tried to turn on again, no luck, no signal, no lights, nothing.... Started to dig, and the power adapter was fine, 24v on output everything fine..
Started to take off the main board and searching for burned components, and after a while i noticed a little "dot" on the regulator..
I thought "the regulator was gone", so, i ordered a bunch of them from farnell, same reference, and replace them, but after turn on the button the regulator is fried instantly.
Anyone has passed for this? Any thought what can be? Some capacitor?
I will leave here a video with test with a controlled power and we can see that the regulator start's to heat up wildly and burn's after a while.

(other question if i can't solve this, the china boards from ebay/aliexpress are reliable?, anyone with one? problems encountered? )
Thanks,
André.
