Try it with another PC to make sure it is not the PC problem.
Otherwise, look inside for bad caps first.

If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Pass and seymour ws 3000 Hooking up to basement I have a white, black and copper wire. On the switch I have a green read and black wire. Black to black. green to ground Red to ?


You're right, green goes to ground.
Black wire connects to Hot wire from breaker box
Red goes to Load (fan, light, motor)

Ok which wire on the switch goes to the Load?
And which goes to Hot from breaker box?

You can test or you can simply hook up the device. If it doesn't work, swap the two wires.
It just won't work until the 2 wires are correct.

The wires should be grey, orange and black, purple, and a black wire. The purple goes to purple, grey to gray. The orange and black goes to the small black wire on your car harness and the black goes to the bigger black.

Trying to hardwire my mini fridge in my popup. I have a blue and a gray wire coming from the condenser and a black and a white wire coming from the thermostat control, and a white and a black wire coming...


ok the black wire from the powersource goes to the (-)negative terminal in the converter, the white wire goes to the (+) positive.
From the converter the white wire goes to the white wire on the termostat.
the thermostat black wire goes to the grey wire on the condenser
the blue wire on the condenser goes to the black wire on the Conveter.
