MacBook Pro chimes the lit screen but no apple logo and won't boot
Hi all. My mid-2009 MacBook Pro 15", which until the other day worked fine, will not boot up. When the power button is pressed as normal the chime plays and the gray screen lights up but the apple logo never appears.
Things I've done:
1) Started up and pressed the Option key - no effect, no boot up options appear
2) Tried to boot to target mode, which it did not do
3) Reset the PRAM
4) Reset the SMC
5) Booting to verbose mode not working
Even though the chime played as usual, could this be a bad logic board? Any other thoughts?
Many thanks!!
