Some light corrosion in different areas. C6452 area, replaced all effected caps and resistors and checked around in diode for any stray shorts, also corrosion at C5101 area replaced all effected along with J5100. L8504 exploded and carbonized, replaced. A spot of damage at the LCD end of the...

I'm having a super weird issue with an 820-00850 A1989, that pulls 20v .01 amps. The board is very clean, and when I remove it from case it pulls 20V .60 amps no problem. When I put the logic board back in the case the problem instantly returns down to .01 amp, this is with nothing plugged in...

Came in with light corrosion around the edges and the usual places, replaced two of the CD3215's and one of their FET's to restore 20V, u7000 area was looking pretty rough so I replaced it for reliability if nothing else. Charger only pulls .01-.03 amps. at U8200 PP3V3_SUS = 0V PM_SLP_SUS_L =...

Board is clean, no liquid a or signs of drop damage. Everything seems to work well except the back left USB-C port does not charge the battery or power the computer, though it works fine as a data port. The other 3 USB-C ports take a charge and operate normally. I'm assuming this has something...

Lately we've been seeing Retina replacement LCD's (full assembly) that are noticeably dimmer then the original OEM. Anyone have any idea what is exactly is causing this issue, is there such thing as an inferior backlight they are using? could it be knockoff LP154WT1 inside? Is it possible its...

We're exploring options for repairing/replacing 15" MacBook Retina LCD's and are looking for some kind of machinery to make the process easier and more consistent. Does anyone have experience using a freezing separator for this (something like the one below)...

Have a 2012 Non Retina 13" i7 with no serial number. Dumped the BIOS and the section that usually contains the SSN is missing from the file. Unit's Serial is C1MMG4VFDV30(On RAM Slot). How do I go about re-adding the serial number? Link to original Dump included

Cleaned a little corrosion near thunderbolt ports and replaced corroded battery but all else looks okay. Runs fine without trackpad cable plugged in, but once trackpad is plugged in it shuts down instantly or in a short amount of time. (tried new trackpad and cable) Any ideas what to check...

Sometimes we get a used SSD with a missing resistor or two. (Samsung MZ-JPV128S) Its always the same two resistors, one or both missing. The thing is the SSD seem to work fine without them, passing diagnostics and performing normally. Can someone shed some light on what's going on here? Are...

Getting this error with ASD OS 162 on Late 2013 13" Retina. Same computer runs ASD EFI 162 without a hitch and passes all the tests including memory. Anybody know the meaning of this?

Very clean board no apparent liquid damage, the trackpad does not move the cursor but it does register the clicks. Tried a new pad and cable no change, there were some crumbs magically around the SMC so I reflowed and ultrasonic'ed, no change. Not really sure what lines control the pad movement...

We are adding another rework station and currently have the AmScope SM-4TP with double boom stand, while it works well the stand takes up a lot of work space. I was wondering if anyone has experience withe the articulating arms they make, such as...

Late 2013 15" Retina (DG) The startup manager screen (from option being held down) is tinted a sort of pale pumpkin spice late color, after selecting the boot device the apple logo is white but the progress bar is tinted, once fully loaded everything returns to normal white balance. Does this...

This particular model seems to suffer from a very high trackpad-cable failure rate which causes the trackpad and keyboard to lose connection. Just curious if anyone has any insight as to why this happens? Seems so odd that they would fail suddenly since their just sort of inert in the case and...

Only visible corrosion on the board was the Jtag and a spot on C8319. EFI ASD comes back with no errors OS ASD Fails Sensor Test (Group #7) I replaced C8319 and U8300 (since it was near the corrosion and seems sensor related) still fails, went ahead and removed the Jtag, no change. where should...

Board was previously ultrasonic'ed, but half of the J9500 collar was lifted up, so I assume there may have been some corrosion there, I re-soldered the the four ground points (pins 51,31,15,49) so the J9500 seems whole again, no other pins look corroded or damage inside or out. Unfortunately...

Had some corrosion localized at the battery connector (J6950) Q7560 and U1900, replaced U1900 associated corroded resistors etc and Q7560. Turns on but still not seeing battery. R5380: 1.9K R5381: 1.9k diode mode J6950 P4: 0.48 J6950 P5: 0.48 J6950 P6: 1.72 PPBUS_G3H: 8.2V with or without...

No PRAM chime, no output device detected, no corrosion. Theres a dent around the audio jack but thats probably a symptom of a frustrated consumer unlikely the cause. I don't have the BoardView for 820-00138 but 820-3662 is close so thats what I'm going by. R6200: 3.3V L6200: 5V Any idea...

I always put the heatsink back on logic boards before testing a computer, am I wasting my time? Is it generally safe to boot without the heatsink mounted?

Fairly clean board no visible liquid damage or corrosion, would crash under certain loads. Running OS ASD162 it crash's (shuts down) the moment it gets to Sensor Group (test #5) every time. Running EFI ASD162 would show IB0R and IPBR failures and finish the tests without crashing. I replaced...
