There was a lot of knowledge displayed above in the "computers" thread so

My 22" LCD just went dark . When the comp is hooked to it the power light
does go green when I input , so I'm fairly sure the logic board is OK . I've
disassembled it and the CCFL's look OK and none of the caps on the power
supply are bulged . I'm not sure it's worth fixing if it means throwing
parts at it . I'd like suggestions on testing the power supply , and yes I
know there are some pretty high voltages present . The CCFL's are a bit dark
on the ends , but not as bad as photos of failed units I found on the
interwebs .

When my DELL 21" failed, I wrote to DELL.
They replaced it under warranty.
