Power button blinks red and then stops.

Hi,

My machine started having this weird behavior, so when I press the button it starts blinking red till the machine heats up then it should switch to green, but now when I press it, it just blinks red then stops, if I press it again it blinks again red and then stops.

I can only manage to make it work if I keep pressing the button till it starts blinking green.

Do you know if it’s some electronic that needs a fix?

Thanks.
