Mbp Won T Boot If Lcd Cable Is Connected Macbook Pro 13 Unibody Mid 2009

Chosen Solution

Macbook Pro won’t boot if the LCD cable is connected. However, it the cable is disconnected and the laptop is connected to an external monitor, it boots up just fine and I can see the OS. Anyone have any ideas? Tried the SMC reset and PVRAM already. Thanks for suggestions.

Check the LDVS cable for bent pins or corrosion. Any water damage or falls? What is the history of the problem?

Also check that the plastic pull tab attached to the LVDS cable is not damaged: it prevents shortcuts between LVDS connector pins. MacBook Pro 13" Unibody Mid 2009 Display Replacement
