I have a Viewsonic monitor model G810.
I'm not getting any screen output at all.
Has anyone here any experience with these units and what goes out most
often on them?
Here are the details.

Viewsonic G810 (20inch monitor.)
Mod.# G810-2M
Chassis Family 21VS001
Ser# Q184052226

I get a power light when I turn it own and hear the relay click
inside, just nada on the screen.
It hasn't smoked or done any arcing etc...
Just thought I'd ask here before I start from scratch.
thanks for any assist.
