K8061 flashing run led

I just finished my K8061 but as I put 12V on the board, the run led starts flashing.
The input leds are working as I can turn the leds off with the inputs.

When I insert the board to my USB port, the power led comes on but thats it no USB led or connection.

I saw in prior posts that I should check pins 1,11 and 32 of IC6, they are all on 5V as they should.
pin 14 has 2,39V

Also I checked X2 which gave me 2,39V and 0,76V(last has a wave on top), I saw that the last should be 1,97V (at least between 1-4V)?

Can anyone give me an idea what to check?

If you have checked all the soldering then it seems that the microcontroller is defective.
Strange that also the USB LED is not responding to the USB cable connection.

Sorry, my bad. After checking all components for the third time I saw that I swapped C1 and C2 :open_mouth: . After changing both capacitors all was well. Great toy!

Thanks for the support anyway

Indeed, that was surely a reasonable reason to all the problems.
Take care and enjoy !
