So I have a Dell 1504FP that I know used to work, but the LCD decided to stop working about a week ago. The inverter and backlights work normally but the LCD is entirely dark. I can see no physical damage on the LCD or connections and have been inspecting the control board.
Is there a way to kill a screen without kicking or smashing it (like static or bad connection)?
Is the screen a lost cause?

I assume the OSD does not lit.  Is there any led in that screen?  Does it lit normally? (i.e. does it change when you plug/unplug the VGA cable to signify that a valid signal was detected).

Without more evidences than what you said and if you have no multimeter to test stuff (voltage levels and continuity tests), I would say there isn't much you can do, sadly.

If someone else broke the same LCD Panel and your LCD Panel is good (but the supporting electronics is faulty) then potentially the parts could be combined.

Yeah the status light does everything it is supposed to, but I have no idea what happened to the LCD.
I am in the process of scowering the electronics. The multimeter may or may not need to come out later, depending on some more tests.
