Messiah 2 Question

[zellar]

Hi Everyone! I had a Messiah 2 installed in my .v4 Ps2. For the first 2 weeks everything was fine. Now when I first turn on the power and go to red light I press the reset and press the open tray and it doesn't open. It just sits at black screen. I have to turn it off and on a few times before it will even show the opening sequence. Then it starts working and everything is fine. Is it the laser going or a loose wire or something worse. I'm going to take it back to the guy who did it ,but maybe you guys can give me a rough idea as what is probably wrong? Thankyou Zellar!
