Is it a Video card Issue? (No Display or Black Screen)

crwdns2934249:0crwdne2934249:0:

I have replaced the power supply of an iMAC 20" Intel a1224(EMC 2210) when i finish and turn on the machine it has no display... I have noticed that the fourth diagnostic LED is not light...

601, 602, and 603 is ON, but 604 is OFF..    would it be the video card issue? just want to make sure before i replace the video card.

== Update ==

two weeks ago, when i received the video card i order online i immediately teardown my MAC and replace the old video card, and luckily the system is now running in very good condition.
