Hi, have a MacBook Air 820-3437 with liquid spill and burn marks at R5100 intermittent power. The number 1 pad is burnt I removed the resistor noticed it connects to many many things. Problem is can't get solder to stick to that pad. I used flux and solder then scraped a little but is not...

Hi Im working on a 820-3437 board I have a second board to compare with. Schematic says there should be a chip in certain location but second board matches first board with no chip there? Am I correct in believing the second board? In the U5000 Group Example R5445,5475 If it runs hot when I put...

Hi I looking at 2 logic boards and there is no component on both boards for the same location. Are the Schematics always correct? I also search for a substitute part. Says should be a capacitor but its black and not grey. I see many places on board that look like components could go there on...

Hi Im working on a 820-3437. R5475 4.53k This is a non current sensing resistor? Need to replace some resistors. Probably blew away don't know. I assume I should order from mouser? Does anyone have their part number? Thanks

Hi Im all setup equipment wise. Where can I find basic Louis? Videos covering heat station temp removing components and soldering and heat station, how to test components? I guess how much time should it take to remove a chip without harming the logic board? Thanks Rick

Hi I have a MacBook Air 1466 EMC 2632 customer spilled beer on it and fried the Trackpad/Keyboard cable connector. Part has much plastic so I assume I can't remove it without melting the plastic. Where can I order the logic board trackpad connector from? Thanks
