I have a Gateway M-Series Laptop, that worked great up till one day I powerd it up and had no video. I'm certain I hear the insides working when booted up, but no video. I was thinking maybe it was the LCD Inverter, but not sure. I hooked up a regular Monitor to it, but nor did that work. So, I'm wondering if it could still be the Inverter or what would be other ideas. Thanks.
