Heatbed and extruder not heating up

After a few succesfull prints in PLA and ABS the extruder and the heatbed won’t heat up anymore.
The 2 red LEDs on the circuit board are also not lid when i activate the extruder or bed via my pc.
The communication beween the printer and my pc is fine as The thermistors measure a correct themperature and i can drive the motors perfectly.
Resetting the pc doesn’t help. Nor does resettingen the printer.

Any ideas? Or should I go for a new board?

You should check the output from the power supply at the blue connector.
Should be 15 volts dc.

The power supply is fine. It puts out 15V.
I think its a fault on the controllerboard.

Do you know which chip controls the heaters?
And Is there a way to check it’s still ok?

Not that I know of.
Others may but this being a holiday a response maybe slow.
It very strange that neither of them work
Have you done anything to the printer?
