Okay thanks. I found the loose wire after having a close look and have it fix. Here is another problem i got after i putting all the stuff together. When I open the game, there was a black screen, if i continue pressing the reset button 4 times, it will show the logo screen then to the browser and stuff, but it doesn't play any ps2 or burned games. If i press the power button 8 times, it will load and play ps2 game. So any solution? And how do you install the firmware to the ps2 again because i am using a new memory card.
Edit: woot, things solved =). Thanks alot guys
