Is it possible for a broken iSight cable to prevent a 2009 Macbook Pro from booting? OK I took a 2009 MBP to the Apple Store/Genius to get looked at as basically it was only getting to the white screen with apple logo. I was pretty sure the hard drive had died, so I left the MBP with the Apple Store for day. When I returned I was told I needed a new hard drive which I expected and also a new Display assembly part 661-5040 because my isight cable was broken or almost broken and it would stop the MBP from starting up correctly when a new drive was installed into the machine.

I basically asked surely a new cable can be installed, but was told a new display assembly had to be installed which i thought was strange and very pricey at £355.
Along with a new hard drive, the Apple store wanted me to pay £598.80 in total to get my MBP fixed.

I basically just wanted to know, if anyone had heard of the an isight broken or wore cable causing a MBP not to startup? 

I've since booted up my MBP with an external drive and the isight camera is working fine along with the display. I've ordered and new hard drive myself to install as £120 for a 500gb drive i thought was too pricey from Apple.

Anyone else been misdiagnosed by there Apple Store???

Any information would be helpful to me.
Unsure about a 2009 MBP, but I had a 2010 MBP that booted fine even when the iSight cable was not connected to the motherboard (the motherboard was new and was being tested before all cables are connected).
