Have a 00165 that goes to full fan immediately upon plug-in (regardless of TP). Checked all rails are present except no VCORE. Noted some solder balls around C1031, but other than that the board looks absolutely fine. All 3.3 V present, all 5V present, all 1.8V present (except VCORE), all 1.2V...

Have a late 13 3662 with no back light and MagSafe stays orange (no charge in battery) history is that water from a faucet dropped on Apple logo over some time. Display works fine, backlight does not. pin 1 at lcd bkltboost registered 0v. No real corrosion on board. Do you think it could simply...

So I have a problem with a 00165 no display/bklt Indeed no display... Indeed no bklt... CPU is warm The following will be obvious if there is fan and there is warmth on CPU BUT: PPBUS-Fine PPBUS S5 HS Comp-8.57v PPDCIN G3H-20.35v PP3V42 G3H-3.42 pp5vs5-s5.13v pp5v-s0-5.13 pp3v3 s5-s0: 3.3v...

Another from my client... They did LD repair, again ended up replacing palmrest, and now just one fan runs at full speed... machine runs fine otherwise. Ideas? (board seems fine).

This is from a repair shop client of mine. They did liquid damage repair and ended up replacing palmrest of a 2016/2017 15" MBP w/TB. It runs for a while, then crashes and says: *** Panic Report *** panic(cpu 0 caller 0xffffff7f90ccb1b5): "Failed to quiesce supporting...

Hi, I have a 3330 with no bklt. External Screen works with screen unplugged. No history. Older machine, very faint corrosion around the board, nothing major anywhere, especially along LCDBKLT circuit. J9000 Pins 2,3=3.3V Pins 38,39,40 (PPVOUT_SW_LCDBKLT) reads 25V. I believe this is supposed...

Hey yall, having a little trouble due to no schematic for the 820-00426 and no donor board... Does anyone know where I can find which component this is? A long shot, but figured I would try.

Have a 2879 when Camera/Bluetooth is plugged in, won't power on. when unplugged, turns on and boots fine. Ideas?

have a 00165 that presents no prior liquid damage or technical work that works and posts intermittently. when it posts, vcore is present. when it doesn't, vcore and pp5v_S4RS3 are not present, yet the fan spins (not fast) for about 30 seconds. However, when it does post, the fan goes to full...

Anyone know of any powering up problems, or shut down problems inherent in these devices? This customer brought it in for me, I inspected it, no liquid damage anywhere... very clean. I plugged in a cord and it fired up... I loaded it up with stress, and nothing bad happened... so I sent it back...

Have a 00165 with some issue. The CPU is getting warm just like the other one I did but there is no short to ground betwixt VCORE and PPBUS_G3H PPBUS_G3H-8.58V PP3v42_G3H-3.43V PP5V_S5 = 5V PP3v3_S5 = 3.32 SMC_PM_G2_EN = 3.42 PPVRTC_G3H = 3.29 PP3v3_SUS = 0V PM_DSW_PWRGD = 3.42 S5_PWRGD = 3.39...

Have a 3662 board with no corrosion, but appears to have no life... However, when im testing around, the CPU gets slightly warm which means its at least getting power. PPBUS_G3H is reading at .5V-.6V. sort of weird. Ideas?

Had a 3476 with some issues, no start, no power, then it would start but kernel panic. Replaced corroded r8185 and trace. powered up but kernel panicked. Ran ASD that failed. Said "ASD-Sensor Failure Voltage VD0R DC-in Failed Value 19.86" and Error 2 Sensor reading above alarm point Any idea...

Have a 3332 with a lot of corrosion, liquid damaged around l7030, j6950, L9830, C7240, C9820, and C1756. No boot or power when battery is connected. PPBUS G3H still present though. Works fine with battery disconn. Think battery is shorted?

Have a 000165 with widespread liquid damage. The wierd thing is when i use a new I/O board, it shows the "battery voltage low" screen (battery with red and the lightning bolt). I tried two other known good ones and same thing. I change back to the damaged original and it doesnt happen...

Have a 00165 that runs ok, history is widespread liquid damage. it seems to suddenly go in to sleep mode on its own... for no reason. it "wakes back up" when you make an input. Ideas? is that PM SLP S3?

Have a 2010 2850, that one fan spins, and the other "twitches"/pulses. Presents with very small amount of corrosion at J9000 but nowhere else. Customer reports that when trying to play graphic heavy games, it tends to crash. I suspect the capacitor for that issue, but cant be quite sure just...

Have a 3476 that chimes on startup, has fan etc. checked all components and traces around u7100, but it either crashes on start up(sometimes), or freezes(mostly) with the apple logo and an empty progress bar. If I change the SSD, it boots but very slowly and then goes right to recovery. If I...

Have a 3437 that lights up logo, but doesnt display. Did PRAM rest, nothing. Looks like it had minor liquid damage based upon palm rest, but it was cleaned. Allsys_pwrgd-3.3 smc_delayed-3.4 L7310-1.75V pp3v3_S0 3.3V pp3vs_S5 3.3 pp5v_S3RTUSB 5.14 Any ideas? I hate these ones.... typically...

have a 3115 with a burn hole under what was f9700. Restored 3v42 to fuse. Burn hole however is puffing smoke when I plug it in and no fan. I've had bad luck with burn holes. Any suggestions? Or junk?
