My previous monitor broke on me and I've had to buy a new one. It was working fine until one day it started getting dim. I compensated by turning the brightness up all the way. Then not long after I started up the computer again and I couldn't see a thing. Monitor was plugged in power light was on switching from orange (standby) to green (connected accessory) when I powered the computer on. When I connect the new screen to the computer it works fine and I get an image. My question is what might have "blown out" for a lack of a more technical term on my LCD monitor and if I can replace it? I would like to have a dual monitor setup. Its an old Westinghouse L1975NW.
