Tea killed my Macbook.

Another dead Macbook pro, deader than dead McDead from dead farm having had a mug of tea through it. Though being a 2012 15″ i7 16GB machine with the dual graphics, its still a highly desirable and worthy machine, rare as hens teeth to buy, naturally customer wanted it fixed. Identified 2 shorts to ground, rerouted those and replaced 2 resistors- still no power. Nothing, no heat from anything. A bit more investigating and it seems the Platform Controller Hub (PCH) microchip is knackerd, swapped that out and we have power. Yay! But no screen. Bums. All the video related power rails checked and present, which lead me to LP8550, which is the backlight driver chip for the screen. No backlight, no picture. Just examining this little micro chip visualy was enough. If it looks like crap, it is crap. tested with multimeter nothing coming from pin 14 – which is …. backlight power to screen. chip removed and flipped over, can clearly see where a bit of tea got under it and shorted it out ( the greenish and grey bits ). New LP8550 , flipped to show what it should look like. Chip put back onto the board, board back into the Mac and boom. Working 100% as it was the day it was new, and at a fraction of the cost from Apple 🥳 #open #righttorepair #apple #mac #macbook #liquid #water #damage #repair #nearme #horsham #sussex #upgrade #service #local #fast #logicboard #tea mycomputerworks.co.uk – macrehab.co.uk
