My 889 has been lying around waiting for me to finish other things on my install for about a month now. Back then it was working great, now, not so much. I've checked all the connections 9-10 times but still get "no signal input". I've read other threads but the answer has always been the connections. Is there a way I can test the signal being sent from the computer? One thread mentioned a multimeter but didn't say how it was done.

One thing that did change on my computer was I got an old LCD monitor from my Dad to replace my even older CRT. I was thinknig maybe drivers got blown out but it would still show something, no?
