If I understand this correctly, the color red does not work on the computer. If this is a laptop, you will have need of to take it to a tech to look at it.



If it's a desktop, this can be cause by one of several things. The first thing to do is ensure that the monitor cable is hooked up correctly. If it is, next check the components.



The easiest way to check everything is to plug a different monitor into the computer. (If the monitor cable can be unplugged at both ends, sort sure that you use a different one.) If it works OK, then you know that the problem near the monitor, not the computer. If it doesnt work, you will probably need to purchase and install a untried video card.



If it does work, though, that means that any your monitor or your video cable is bad. Try plugging your monitor into a different computer (again, rather, use a different cable). If it works, then you dont call for a new monitor. But if the monitor still doesnt work correclty after hooking it to a different PC, you necessitate to replace it (you can get a single color gun replaced, but usually costs more than a foreign monitor). If the monitor is still under warranty, the businessman will fix it - but in my experience, it take several months.



If the computer and the monitor both work when hooked to different systems, you will just stipulation to replace the cable. You can pick one up at any office supply store that sell computer peripherials for under $15.00.
