I just installed a neo 4.5 and my cd tray will not even eject!!!!!

[A03]

I had a problem once with the Neo4 not ejecting the tray correctly and I found out that it's Ribbon cable..However that was my case..If it's get beyond repair my adivce is get it check out by pro..Believe me YOU DO NOT want to temper with it yourself I learned the hard way when 1 of 2 Neo4 machine's Ps2 Board was fried in the process..Take my advice..Get a pro if you're not sure..
I could tell you to check this and that but it won't do any good once it's dead is it?
