so i just picked up a 15" Macbook pro that is needing some fixes first thing is the macbook pro wont charge, i have another macbook pro that i tried using the cable from and that didnt fix the issue so i took the battery out of my good macbook pro and she powered up, however there was no audio and the screens backlight was not working, i could shine a flashlight on the screen and see mostly what was going on and the thing i noticed was when i turned the volume up and down the icon on the screen that shows where the volumes at always show a circle with a line through it right under the volume bar not sure how to correct that issue. so far i have done a pram reset, and i have powered down the mbp disconnected the charger and removed the battery and then held the power button down for seconds and restarted it and nothing. i removed the top cover to open her up to see if there was any loose connections but i couldnt find anything anybody have any ideas? also the mbp is running 10.4 currently not sure if that matters for these issues but i plan on loading 10.6 on it once she is up and running decently. does anybody know what connector goes to the back light and what voltage is suppose to be there?
