I was wondering if it makes a difference if I place 2x4gb or 4x2gb Ram Brackets to have 8gb ram in total. I have 4 Ram slots ...
Ok, this problem will be challenging to solve. But I hope there is a Whiz who can help me out. - Problem : Macbook won't boot...
Have you tried resetting PRAM ? (Booting with Cmd+option+P+R keys) Next step you can do is trying to reset SMC. (This progress is hard to explain so I refer you to apple's website for that Resetting SMC) Next up is finding the connectors on the logic board which lead to the backlight. If you see any corrosion/solde<wbr />ring damages, then u might have located the problem. I do not own a tech manual for mbp atm but I'm sure someone on this website can provide you with the location of the connectors on the board.
