MacBook Black Screen / White Light no Chime

So I was on my MacBook 13" White and doing some work. Worked great! Next day I powered on and I only get a white light right. No chime, no nothing. The dvd drive wont accept disc.

I removed both memory and test in another computer and they both worked great. Im aware of gpu reballing but this is not the case here because I should still here the chime or having the dvd respond to disc.

I did holding of power button for 5 secs crap, reset pram....nothing.

Anyone here can tell me what component is damaged or what to look for, PLEASE?

I've taken out the logicboard and it's now in my hand.

Any help will be great!
