My Westinghouse monitor is not going on but the power light is on do I need another monitor it is 5yrs old or more

It could be your monitor driver card that is bad.
Before you go buy a new monitor, do a quick test on
connecting the monitor to a laptop or portable computer if you have one,
or if you can, get a friend that has one a laptop and use the monitor
signal cable that is already there, and connect it into the
temporary or borrowed computer to see if you get a picture.
Your borrowed computer will need to know that your attaching
and external monitor, so that will need to be done to let the
new computer being used, to know that it is being attached.
If you get a picture, its your old computer driver card.
If it still stays blank, or no picture, then your 5 year old monitor is bad.
Also, but unlikely, it could be the monitor signal cable that
is bad, in that case it will not work on either application.
You could substitute the cable to make sure its not the cable also
for a quick check, on both applications.

The screen is blue and greem

The most probable cause is a break in the cable (red signal line). Try gently wiggling the cable at the computer connector and right at the monitor - these are the usual places for breaks. If this brings the red back into the picture (pun intended), you'll have to find a way to repair or replace the cable.

If you have red or white when the cable is disconnected (check cable warning message) or in the monitor adjustment menus, it is definitely either the cable or the computer video card.

If you can't get red to work at all with the tests in the preceding paragraphs, then it's time to open up the monitor. Check for continuity on the red line (pin 1 on the DB-15 connector to the red shielded wire where the cable terminates inside the monitor). Note: if you are not comfortable working near high voltage or don't know what not to touch, leave this task for an electronic technician. If the cable tests good, then it's time to troubleshoot the red cathode driver circuit on the CRT board, starting with the input signal. You'll probably need an oscilloscope for this job.

Heavy white lines accross the screen

Replace it, it is going bad. I could tell you what would cause this such as bad driver IC etc. but bottom line is its five years old, you got your moneys worth out of it so bite the bullet and get a new one.

some how your screen resolution has changed above or below what your monitor can display. you need to boot your computer using another monitor that can work with the resolution your computer has switched to(i used a spare crt monitor when it happened to me) change your resolution in display properties to a normal level like 1027x768, and while the computer is on swap the monitor cables to verify the lcd is working.
It is perfectly safe to unplug the video cable and plug it back in while the computer is turnned on.
