Liquid damage to logic board, no video
Hello!
I went toe Apple Store because my MacBook Pro retina had no video, and I had heard that they recalled similar models. So I went to see its eye would replace mine, they told me that I had liquid damage to my MacBook. I recall no spills, so it had to have been placed on something wet and leaked through the vents at the display. Which would explain why I have a red indicator and my display isn't working. I took the back off to assess any corrosion. I had to do it wuickly because my two year old thought she was helping. She wasn't. All I noticed was it was EXTREMLY dusty, and there was something sticky and when I wiped the dust away it showed a small stream of liquid on the backing.
Anyway, tonight I plan on disassembling it and cleaning the board to prevent further damage.
Here's the problem: I have no video, failed flashlight test. Battery "needs to be checked soon. All other major components are working perfectly and the external display works too.
I just want to know if I possibly find corrosion to the display connector, and I clean it. Will my display work again? And if it doesn't what first her steps should I take to make my display work again? I would prefer to shell out as little money as possible. I'm also not super experienced in repairing electronics, but I can follow directions well.
