Display is black, do I need to replace logic board?
My MacBook Pro 13, MD101 (Mid 2012) suddenly flickered, then the backlight died, but still picture on the LCD, then totally black.
Sent to repair via the shop, they claimed liquid spill and quoted repair cost of 2800 USD approx (this is Danish price) for replacing logic board and display modules.
Of course rejected.
Got it back, opened it, indeed a small area of corrosion in the corner close to the display connector.
Cleaned with Isopropyl alc. - took out the connector etc. cleaned, dried the connector both ends, put it back in place.
Boots up fine. External display is fine. All is good. Except the built in display is dead.
Had a small repair shop take a look - they state the display module is OK but something burned on the logic board around the connector and quotes a new logic board is needed - same price as a new machine.
Issue: I don't really trust them.
Question: Does this sound feasible? Is a logic board replacement typically needed due to minor liquid spill and when the board works in all other aspects? Any hints appreciated.
Is this a good question?
