Seen a few dead LCD screens, never seen one with a green haze though, I have seen an old CRT screen with a green haze, that turned out to be the D-Sub plug on the monitor, one of the pins wasn’t making a good contact, I know you say you have tested the leads but have you tried plugging it into the other out-put on the graphics card, as in the one that has the good screen on?
It could be a dodgy connection if its connected to D-Sub and not the DVI.
Anyway if it is dead, I would probably go for the 19 Inch Samsung, the 17 inch wide screens aren’t very big and that extra 2 inches does make it better on the eyes.
It’s a shame you live a few miles away Freddy, I have 2 LCD screens here, both are up for grabs, a 19 inch LG wide screen and a 19 inch 4:3 Samsung, am asking for about £35 each for them.
PS: Im not going to be around the forum much am having a new gas boiler put in.
