Well, the good news its not your LVDS cable! The bad news you do have a logic board issue. ;-{
 
The issue you are facing is related to the video MUX logic within the Intel Eagle Ridge Thunderbolt chip. Basically, the video signal is sent to the chip and then its driven to the internal display connection and the Thunderbolt port.
 
This logic in the first models had issues. Apple had aan extended warranty program to replace the logic board. Sadly, its long expired. The Green outlined chip is the one in question
