Startup failure right speaker crackle sound
I'm not sure, I looked at the guides but couldn't find my problem.
Symptoms:
Won't startup past the DVD drive spinning up. I hear a sound, but it sounds fuzzy/crackly from the right speaker (nothing in the left one) .. it lasts for about 3 seconds.. then the entire thing resets, process repeats continuously but without any crackling sound.
Update 1/9: Screen never turns on, always stays black, checked from angle to make sure it's not even slightly on.
What I've done:
Tried PRAM and SMC resets
Opened it and blown it out... not sure what I might have to replace
Update 1/9: Taken ram out and put it back it (it was brand new ram, certified for this model)
Any ideas what I should do next for trouble shooting?
Esta é uma boa pergunta?
