That's why I took the entire motherboard out in the first place. I spent 2
hours desoldering and reflowing solder all over that board!

Hard to imagine a capacitor having dried out, but I can't rule out a
defective batch (as what happened with Gigabyte motherboards a few years
back) either. I just don't have any documentation by which to trace out the
suspect components. Shipping it to a repair facility plus the repair cost
will cost as much as a new monitor, and I may not get as perfect a tube. I
hope my other NEC AS120 isn't going to follow this one. I rely on them both
very heavily.
Oddly, my wife criticized me for setting my Windows standby timer to 5
minutes. Perhaps having it shutdown so often has stressed the components
with extra startups. But at $240/month, I can't afford to let the monitors
run when I'm away from my desk. Ggggrrrr...
