I have a Hp Pavilion ze5200 that the backlight seems have gone out on,i say backlight because if I look at the screen at a certain angle I can see the computer booting up. Replacing the screen should solve this problem, correct? So i bought a new screen, hooked it up and nothing happened. What else do I need to be looking for? Oh, If i hook an external monitor up, it does work.

Old screen reconnected now,unplugged inverter with computer running and nothing changed,. Monitor stayed the same and did not go off, but no backlight. Would this be an indication of bad inverter?

New screen appears to be completely dead.

Well if an external monitor is working that tells us the motherboard is good. Now, typicality when the backlight goes out replacing the panel will correct the issue. It is doesn't we have to take a look at other components that control the video. The cable and inverter are left, it is possible the inverter has/ is also bad and given the issue you described it does sound like the inverter vs. cable, but it wouldn't hurt to get a cheap cable while your ordering a new inverter.
