Having problems with your Computer Monitors ?

I need to know if the center pin is positive or negative on the power plug on the back of the pavilion f1503 LCD monitor.

Answers :

I assume that you need a new power supply (PS). The old power supply should have an indicator on it depicting the pin-out. If it doesn't, you can break open the old PS and look for the capacitor. One end will be market +++ and the other pin will be marked ---. Trace the wire of use a conductivity meter to determine which wire is + and which is -.

Most of the time (but not always), the center is + and the outside is -.
