so i got this pre-unibody mbp, approx. 2008 i think (only five yrs ) last time it shut down, it seemed to have just gone off without properly shutting down. since then, no boot up chime, no pic, sleep light is permanently glowing, nothing else happening... target mode isn't working, either tried booting from usb stick and cd (cd is stuck in there since - how to recover that one??) charger is working and charging the battery ok tried smc and nvram resets several times replaced ram, reseated them several times took out hdd, connected to another computer, drive is working fine the fact that booting up without any ram doesn't give any beeping errors seems to hint to some dead logic board, right? or what else? thing is, all repair centers here in switzerland want around 150 usd for just looking at it - and if it is a logic board, i seem to remember this costing over 700 bucks... i'm broke and don't think that would be worth it then... any ideas what i can do now?
