My Dell 1504FP, Flat Panel Display is displaying nothing. Screen totally black. The power button lights up, first orange, then the yellow-green color.
Turning it on and off makes no difference. Using on a Dell Dimension 4500. Swapped it on to another Dell Dimension 4300, still no image display. Put a good monitor on both computers-they work fine. Checked continuity in all 15 conductors of cable-OK.
Where do I look? Sounds like a power suppply problem, but I have no schematic. A few months ago it was occasionally intermittant, would work after repeated on off cycles. Now it is DEAD!
Any help out there? It is one month out of warranty!!
