Is the Logic Board the Problem?
I just replaced the DC In Board a few days ago and I'm still having problems with initialization. I wanted to try to less expensive 'fix' first. This Mac is 5 years old. I'm not sure it's worth it, but I'd like to keep it going for sentimental and convenience reasons, plus I can't afford another __book right now.
- 1 Initialization is slow or freezes--before I can log in
- 2 I noticed some pixels MISSING from upper Left corner during an initialization that wouldn't progress
- 3 Freezing immediately after initialization--after login--or at some point...no pattern to it.
- 4 No 'Apple' chime when I push Power button, but after done initialization (if it can complete it) other sounds are fine--notifications for alarms, other widgets, I can hear audio from videos.
What do you think?
Thanks for your input,
Puzzled, yet Resigned Sylvia
