Expert:  Steven replied 1 year ago.

I understand, also not the problem. In order for the back lights to come on when you press the power button you need the p on voltage and the drv on voltage to power supply, check those two voltage when you press the power button and see if they come up?

I believe it is pin 1 and pin 9 on P201 on the power supply, let me know what you get?

Expert:  Steven replied 1 year ago.

Do you have a meter? and the ability to check these voltages?
