My MacBook Pro will not start even in safe mode
My MacBook suddenly turned off. I couldn’t restart and saw that the power chord was frayed. Used another chord but when I pushed the start button, the green light would go off, no sound. Tried PRAM sequence and seem to start (gong) then turn off. Meanwhile, I had a CD which I needed to retrieve so I opened the back, took it out but in the process the subwoofer connector socket came off as I tried to unplug.
I removed the memory (both-same time), restarted with the PRAM sequence and heard the fan running, no gong, and a black screen.
1. Can I diagnose with the plug issue?
2. Where do I start to look into the real issue?
Thanks for the help
