Hate these ones lol. Board powers up sometimes, but most of the time when plugged in has a very dim green light and no fan spin. Looked totally clean, no signs of liquid damage. PPDCIN_G3H fluctuates from 16.3v to about 16.7v every few seconds, and PP3v42_G3H fluctuates similarly except just...

Hey guys! New forum style, neat. Haven't been here in a while lol. So I've been dealing with this guy for a while--original problem had no backlight, had some liquid damage around backlight chips/lvds connector, cleaned 'em up and resoldered new connector. Have image, but still no backlight...

Have an 820-00165 with water damage on both sides of the board where the SMC is. Cleaned the corrosion and board powers on w/charger, but will restart after a few moments on the login screen and will not power on w/battery at all. Before I start poking around at rails in the affected area...

This guy had no backlight, replaced U7701 and cleaned up corrosion on the PPHV_S0SW_LCDBKLT circuitry. Board boots fine and works perfectly now, except for when it tries to go into Sleep Mode. Once it fully enters Sleep Mode, the computer fully turns off. Fans have stopped spinning, keyboard...

Noticed a thread very similar to the one I'm making posted a few years ago, but it didn't get anywhere. 512GB SSD, looks in prime shape, no corrosion/visible damage of any kind. Refuses to be detected in two good machines that detect other SSDs. I can recognize some data-lines here, but unsure...

Plug in the 60W OEM magsafe, you usually get a green light w/fan spin, no chime/display/anything. Fan continually runs higher and higher etc, the usual. No USB activity/no beeps when ram is not inserted. Occasionally, when optical drive is connected, you'll get the whir of the optical drive...

So this guy had some ISL trouble, fixed er up and replaced the SDA resistor for the battery as well. Boots, detects battery and will charge it, but after a certain amount of time, the magsafe LED will just turn off and the machine won't take charge. Unplugging and plugging the magsafe back in...

Board has all G3H and s5 rails in good state, everything else is pretty much missing. Just repaired this one for a LCD connector (no backlight) and was working fine, put er in the ultrasonic for cleaning (had some minor corrosion about), alcohol bath, then dehydrator for a good 20m-30m. Tested...

Dim green light on magsafe, somebody had apparently tried to repair this board previously... both ADAPTER_SENSE and PP18V5_DCIN_FUSE jump every second, SENSE between ~3.9v to ~4.1v and FUSE between ~17.1v to ~16v. No shorts on any of those lines, and PPBUS_G3H descends constantly from around...

Liquid damage wasn't too extensive, but particularly bad regarding the pads of F9700--the corrosion essentially ate it's way thru some of the board, and there's a shallow divot where the pads should be. Otherwise, some slight corrosion and a totally burnt out L9004, same issue with F9700 where...

Liquid damage pretty extensively on the I/O board, but the main logic board was mostly untouched--only slight corrosion around U7330, nothing on backside. Cleaned her up, no change in magsafe (goes green, then amber), fans do not whir. All main power rails are there, PP5V_S0 and PP3V3_S0 are...

U7090 gets 15v nice and steady on pin 6, middling around .252v on G3H_SW on pin 4. L7095 shows 0.00 on diode mode, when I remove L7095 pin 4 of U7090 shoots up to 14v and diode mode returns a normal reading of around ~.3 on L7095. When I replaced it with a good L7095 tho, the short returned. Not...

Got a Mid-2015 15" retina board here, everything works fine except for the backlight on the screen. LVDS connector had corrosion on pins 2/3/4, LVDS cable had corrosion similarly on both LB and screen side in the same areas. Connector cleaned nicely, but the LVDS cable had pin 1 basically broken...

Hey! This time I actually have a 2012 13" board, 3115-B. Similar problem to last time, except this guy gets no power even with battery plugged in. When AC adapter is attached, sleed LED lights and fan spins for a quarter-second, then rests. Board does power on in SMC bypass mode. Board had...

EDIT 820-2936-B board, 13", board receives power well but when power button is pressed the fan will whir and the sleep light will come on for a moment, then abruptly cut off. When I keep only the charger plugged in instead of the battery, eventually after many cycles of doing the above the...

Hey! First post here, hope to be an active member of the community once I become a bit more experienced. :) 2015 13" MBAir board, had some liquid damage on the I/O board and no light on magsafe even w/new I/O cable so I bought a new I/O board. No viewable liquid damage at all on main logic...
