I can't see some light colors using this moniter. For example, in Facebook, there are blue boxes around comments. I can't see those at all. I've tried messing my settings, but haven't really been able to sort it.

This could be a result of multiple different variables. If its a CRT monitor, it could be magnetic interference that is causing it. On an LCD screen, it could be your video signal. Check the cables and make sure they are plugged in tight. Check to make sure there are no power lines or magnets around the monitor as well. Turn off any lighting in the area and see if that affects the monitor. Also you can test the monitor on a different computer to see if you get similar issues. If so, then you may need to replace the monitor or it's cable.

Take it to GameStop. They can find the problem lickety-split!

ok your monitor is a separate issue and start by checking the blue signal lead from the back of the monitor because for some reason the monitor isn't getting any images to show

I think you are SMURFFED. Bad! Get a color sample and go change the shade of blue.

that will be capacitors problem in power board in the moniter

If I understand correctly, you are replacing a switch with the EJ500 timer.
You mention a 'plug'

The EJ500 has 3 wires: Black Red Blue.
If you are replacing a single-pole switch:
The switch has 2 wires, one of these wires is the Hot-from-breaker and the other wire goes to Load:
Timer-black connects to Hot-from-breaker.
Timer-blue connects to wire-going-to-Load.
Timer-red wire is capped off. Red is not used for single pole switch.
If you connect wires and your lights blink, then you put the red wire where the blues wire should go.
If you connect wires and lights do not operate, try reversing the blue and black wires.

I posted images of EJ500 wiring (the Intermatic EJ500 and ST01C have identical wiring
http://waterheatertimer.org/ST01C-program.html#ST01C

If you are replacing a 3-way switch, the wiring is more complicated.
The EJ500 can not replace a 3-way switch wire-for-wire.
Diagrams on link above show wiring for 3-way.
Add a comment if you need more help.

You need to open it up and look for bad caps with bulging top first, post back what you see so we can guide you further, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
