This macbook turns on with no backlight and soon after the backlight tries to turn on and then goes back out. It boots up to the login screen and then whole computer shuts down. I notice the computer only turns on by itself and not when I press the power button. Except when I do an SMC reset the...

Hello all, Am trying to repair this formerly damaged macbook pro. The original board was so bad that I decided to replace it with one from a cracked screen MBP. This new board seems all fine but boots into a folder icon. The mac passes the hardware test with no isssues. When booting into...

Hello all, I'm having a bit of a hard time fixing this board due to the lack of board view and the less than common issue (for me). Boots up fine, screen is working, just no backlight. When I measure pin 1 of the LVDS connector I get no attempts of producing voltage. There is 5V getting to the...

Hello, I have this board which wont turn on. When plugging in the USB C charger I get a current draw of about 20mA. I don't have PPBUS_G3H voltage. My best clue so far is that when I measure PPDCIN_G3H I get around 5.2 volts and occasionally, perhaps as the board tries to turn on, it dips down...

Hello all, Am attempting to repair this board which has no green light. It has all the G3H "always present" voltage rails except that PPBUS_G3H is 8.1V. It is not going past this state and S4 and other voltages from there on out are missing. I can't see any shorts atm nor do i see an attempt...

Hello all, I have this 810-00165-A board with no power or green light. I have verified the G3H voltage rails and have found PPVRTC_G3H rail to be missing. I traced it back to U1900 and found that itself is not getting any voltages except PP3V42_G3H on pin 13. The rest of the missing voltages...

Hello all, Yet another macbook I could use your help with. This initially didn't power on. I found U5580 to be corroded, this was replaced along with C5580.SSD current sense circuit. I noticed after some work that R5585 is missing, not sure if because omitting or if I knocked it off during...

Hello all, I got this weird laptop that supposedly wasnt turning on. I let it charge for a while using a known working motherboard and it eventually turned on. With its original MOBO I notice it charges but does not show the typical lightning bolt on the battery icon, it shows nothing at all...

So as I mentioned in another thread, i'm new to specializing on apple products but old to being in electronics service and repair. One of the things that are becoming very apparent to me on doing this field of work is that parts can be expensive because they are related to the apple name. I I...

I'm trying to set up a bench power supply to power all my logic boards under test using just the adapter tip from a magsafe charger. See this link https://www.amazon.com/Droya-Repair-...ateway&sr=8-50 What I want to know is if those tips will report as 85W or anything lower which would be a...

I have just gotten into board repair. Have been a technician for other electronics for several years but am just now specializing on laptop/macbook boards. I'm thinking of doing a flat rate. What would be a good charge for macbook board repairs? I see may mail in places will charge anywhere...

Hello, New to the forum, so glad to be part of it! I have much experience with electronics but not as much with MBs though I have experience there too. This is my first time working with a shop that will hire me if I can prove I can fix boards for them. I have gotten a macbook air with no...
