OK, have a liquid damage 15" retina. the only thing wrong with it is the power button. Have any of you guys had any experience with fixing the power button circuit without just replacing the keyboard or top case. I am still a rookie so I do not know if this is a stupid question. Just seems like...

Back for more fun! I have a 15" retina pro with no backlight. I am attaching a photo of the area that suffered some liquid damage. The issue is obvious, so my questions are: 1) Louis do you have these lvds connectors for sale? Are the connectors the same from 2012 on? ​2) I will replace the...

So I have a 15" retina, finally something worth fixing. However, has been eaten alive by coke I guess. Well, decimated the thunderbolt circuit and charger circuit. The Diode D7105 has only pin 3 pad left, but 1 and 2 are gone. I want to focus on these two first. I am trying to figure out the...

Has substancial liquid damage. Have PP3V42_G3H, PPBUS_G3H,SMC_BC_ACOK(3.23v) When I check the power on pads i get 2.4v for SMC_ONOFF_L. Not sure what is pulling that low. I do not have an ultrasonic to clean the board. Any thoughts? I have checked the ISL6259 and have 4v on ac in, I have pin 14...

OK, so i read something in one of the forums and it got me curious about the other logic board like this one had so i plugged in a charger and tested some points. Everything was as it was before, seems like it should work but did not. Then I felt the ISL6259 chip and it was very hot. So I put...

So I have PP3V42_G3H on the one wire circuit coming through pin 1 of C6908 and other areas. How do I know if i have a bad U6901 vs a bad via?

Ok, I just joined and have to admit i am a little intimidated! I am a rookie. I get green and orange light on charger, boots, chimes, no back light at all. Computer will not power on by charger alone it must have battery to power on. Inspected back light circuit to discover R9703 missing...
