Looking for a part number or some sort of identification of the capacitator (i think) that burns out between the ‘D button and LT. it usually makes a small melted spot there in the case and the controllers with this problem will not turn on/stay on.
If there is only a capacitor just remove it.It for protection check the size and fixit no matter the value is on there.If there is another parts so you have to change.
