Black screen I switched to another outlet and turned the computer on, I have both green lights on but the screen is black? I do not know how to get a picture or anything.

Get two short extension cords and cut the FEMALE end off each one. Strip back the insulation on that end. Connect the two green wires to each other, and connect the two white wires to each other.

Connect one black wire to a light switch, and connect the other black wire to a 20W appliance-type incandescent light bulb. Also run one short black wire (from a cut-off end) from the second terminal on the light bulb to the second terminal on the switch, like so:

plug -- black -- switch -- black -- bulb -- black -- plug
plug -- white ----------------------------------- white -- plug
plug -- green ---------------------------------- green -- plug

Turn the switch to the OFF position.
Start the generator. Plug one plug from your new rig into an outlet on the generator. Plug the other plug from your new rig into a wall outlet supplying 120V. With the generator running, turn the switch to the ON position.

The bulb should flash for a short while, then become steady. When it's steady, that side of the generator is flashed. Repeat for the other side of the generator if it makes 240V.

1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

if the power indicator light from green then turn to red with no display, check the power supply board which may have leak or bulged capacitors. check also weather your vga cable is good, if no signal the monitor will turn to off.

Switch-plug combo:
bare ground goes to green screw
dark screw goes to hot from breaker
silver screw to neutral
brass screw goes to load (light)

You are replacing single pole light switch?
Single pole switch has 3 wires: black and red and bare copper

New device has 4 different colored screws: green, dark, brass, silver
Bare copper goes to green screw.
Black wire goes to dark screw
Red wire to brass screw
Nothing on silver screw for a moment. Test circuit and make sure light turns on-off.
If lights works, then good so far.

Now let look at silver screw. Neutral wire has to connect to silver screw.
In back of your electrical box are white wires twisted together and covered with wire nut.
These are neutral wires.
You must connect another short piece of insulated wire to these neutral wires and run that wire to silver screw.
The neutral wire will complete circuit to receptacle.
If you do not have neutral wire, then receptacle will not work in that box without additional wiring.

Hook up neutral wire to silver screw.
Now turn on power and click switch again.
If circuit breaker trips, then reverse your red and black wires.
Otherwise this should be correct wiring.

Make sure you turn off the power at the power panel.
If you are lucky you will find the following in the electrical box behind the light:

1. A black wire that brings power from the fuse/breaker panel--connected directly to one or two other (black) wires (not to the light).
2. A white wire from the panel--connected to one or more white wires including one to the light.
3. A black or white (maybe taped black) wire that comes from the switch and is connected to the light.
4. A green or bare wire connected to the box and maybe also to the light.

If this is the case then you can run a new cable to a new electrical box in the wall for the GFI. Connect the new black wire to the Line In terminal/black wire of the GFI outlet and to the group of black wires in (1) above. Connect the new white wire to the Neutral terminal/white wire of the GFI outlet and to the group of white wires in (2) above. Connect the new green/bare wire to the Ground terminal/green wire of the GFI outlet and to the original box or ground wire. If there is a Load/Feed through wire on the GFI outlet, tape the end of it and do not use.
If the black and white wires described in (1) and (2) above do not appear in the electrical box at the light then they are probably in the switch box and there will be only one black wire and one white wire that connect to the light on the wall. In that case you will need to run a new cable from the switch box to the new outlet. You will not be able to wire the new outlet from the existing electrical box at the light unless you do it through the switch and it will not be on unless the switch is on.

you should have 4 wires total (not including grounds, which get twisted together and connected to green screw) you have to know which is the power lead, and which goes to the light! 2 blacks, and 2 whites ...the 2 whites go together and connects to the silver screw, and the 1 black power lead goes to the gold screw, the other black wire(to the light) goes on the opposite side of switch above the silver screws on another gold screw

try testing it in another outlet a known good outlet if it powers on then your outlets bad if it doesnt means a bad cord or bad monitor

I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?
I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.

i think screen card need to be changed by a techniquian
