I have had my LCD for about 2.5 years now. I was using it with a DVI connection and recently it stopped working when I boot up the computer. The light on the monitor just keeps flashing and nothing ever displays. I switched to VGA (analog) and it worked, but the next day, the same thing started to happen. I decided to test it on my brother's CPU, and his old 15 inch HP CRT monitor on my CPU. Lo and behold his monitor works on my CPU, and my LCD works on his computer. What is the problem and how can I fix it? Thank you.
