I have a 17" Trinitron monitor that had bad solder joints, it took a few tries to fix it but I finally did.
That was a few years ago when a CRT monitor was still worth something, I had also bought it new so I didn't want to toss it, now I'd probably just pick up a used one somewhere.
Monitors, especially better monitors with all their boards and shields are a huge pain in the butt to work on!
I just replaced my 21" Sony with an HP LCD 16:9 monitor I got for Christmas (a couple weeks early
) I don't regret it at all as I reclaimed a bunch of desk space and it only weighs maybe 5 lbs compared to the Sony's 68 lbs!
You'd be welcome to the 21" Sony if there was a way to get it to you, it's cosmetically challenged but works well.
