So came home from work this morning and my 2007 MBP has no display. Tried pram reset, no luck. No keyboard lights, only the front power light is showing. Any hope for this or is it time to start deciding on an iMac?
If you're lucky it's not the GPU but the soldering that's faulty.
My 2007 MacBook Pro will cold boot to a black screen. Booting while the machine is warm/hot and everything's fine again.
Here's something you can try: start your Mac and put under a blanket until the fans come up running at full speed. Then reboot.
Alternatively, you could try to blindly log in, start terminal.app via Spotlight and type 'yes'. This will max out one core of the CPU. Open another terminal window (Cmd+N) and start 'yes' again, this too will get your laptop to heat up quickly.
I know intentionally putting it under thermal stress sounds scary and will eventually kill the laptop for good, but its not like it could get any worse right now.
I just hope mine survives until the Broadwell MBPs arrive
