Chosen Solution
Hi all, My Macbook Pro 13” Retina late 2012 (A1425) has fast pulsating rolling lines in the display. Very intermittent problem, might only happen for 5 minutes in a 8 hour work day.
Sometimes twisting or putting pressure on the display or lower body will fix it. Problem does not occur with external display & screen capture doesn’t record the lines. Do you think it’s most likely the display cable or connectors?
It’s clearly something within the display its self. I’d say its quite odd! The only thing I can think of is the T-CON logic within the display (at the bottom edge) is messing up. Unlike older Unibody systems which used LVDS signaling your retina model uses eDP signaling. Its like the difference between Analog Vs Digital TV signals, that removes the cable as the source of the problem. Here’s a breakdown of the display assembly MacBook Pro Retina Display Teardown At this point I fear you need a new display assembly. Reference:
