No Video Ps2 v2

[supersquirrel0]

Here's the deal: I have a v2 and I want to get a Messiah 2.........while im saving up for that I decided to go ahead and try to unsolder those notorious 4 pins to get access to the bottom of the board. After 2 days and 2 different irons (30 and 40W), i finally got them apart. So far so good. Now, when I put everything back together to see if the damn thing still works, it boots up fine. I stick in Ace Combat 4 to test, and the screen goes black. I try to restart, and the screen remains black the entire time, like there is no video or sound output. Any ideas or suggestions?

Fixed it! I didn't realize that you had to RE-SOLDER those 4 pins...........
