Fix Your Computer Monitor: When the light is yellow or amber, not green
If you've purchased a new computer or moved an old one, there are many things that can go wrong. Computers are tougher than they look in some circumstances but they are also very fragile when it comes to random glitches happening.
If you have a problem involving your monitor working fine and your computer working fine but your computer display not appearing on your monitor, you can try the following steps to solve the problem.
This applies when you're monitor appears to be in working order with the amber/yellow light showing and the computer operating but no apparent communication between the two. If your monitor won't come on at all, it may be time to get a new monitor!
Step 1 - Check the Monitor
This step may depend on what other parts you have in your house but it's a sure way to make sure that the computer and not the monitor, is in fact at fault.
Simply swap the monitor to another computer. If the monitor does work with the other computer, it is definitely not a problem with the monitor.

Step 2 - Check the Power
Trace each cord and make sure that the cord connecting the computer to the power, the monitor to the power and the computer to the monitor are all plugged in and turned on.
Step 3 - Check the Connection
This is an important step that can often easily fix your monitor. You need to make sure that the cord that connects the monitor to the computer is inserted into the right plug. In some cases if you don't remember exactly which plugs went where, you may accidentally plug the monitor into the incorrect socket.
Try plugging the monitor cable into each socket that will take it and testing. Remember these sockets may be horizontal or vertical.
Step 4 - Hold the Button
This one wipes some of the minor memory in the computer and can fix the problem.
Simply turn off the computer, remove the power cord at the back and then hold in the power button for 30-60 seconds. This will remove any left overcharge in the capacitators and often fixes the problem.
Step 5 - Ram & Graphics Card
If you know something about how the insides of a computer work, locate the graphics card and reseat it (basically, unscrew it, pull out, push back in and screw back). If you've moved the computer the graphics card can often wiggle loose.
Attempt the same solution for the ram.
Step 6 - If all Else Fails
It's about time to either replace a part or ring a computer technician. Chances are that something has been broken or a fuse has blown and this will need to be located and fixed.
