I have a A1706 with a 820-0092-A Water damage near UB400, and bad corrosion at J6600. Ultrasonic board, cleaned up well, and no obvious signs of damage. When plugged in, no fan spin, but pulls 5V fo 3 seconds, ramps up to 20V @ .9 A. After 30 seconds, settles down to .26A After a little...

That document most definitely helped me, big thanks ! Do we have an area for docs like this ? PM_PWRBTN_L, check for pulse at PM_SLP_S4_L : Both pulse when I ground SMC_ONOFF. It drawn a little more power briefly, then goes back to drawing 0.09A

Checked 3v3_SUS @ U6100 pin 8 ,C6100, R6101, U8130 Pin 2, R8133, R1583, R1581, R1590, R1580, C1206, C1202, C1204, R1549, R152. All pined @ 3.3V I'm a bit green.. Would need help with " Trigger SMC_ONOFF_L and check for drop pulse at PM_PWRBTN_L " Not sure how this is done?

820-3476-a A1502 Fixed blown cap and resistor and still issues. Came in no boot. Removed logic board and found C7536 blown, C7537 and R7536 looked like hell. Replaced them both, and unit had fan spin. Reassembled unit and no boot ? Ok, let's take it back apart. Power supply shows 0.09A...

Oddly enough, the pads that lifted are not used. The half pads I was able to use and were still connected. I believe I'm good, I'll assembly and test. Purchased ZXW to confirm pin location to components. They ohm out, so I may just have lucked out being able to repair. I'll double check with...

Thanks for sending what you can. I have nothing to find the other end. I would like to fix the traces as it seems easiest (I would imagine anyway) I just don't see what direction they go, or where they end up?

I have a iPad 8th gen, A2270 and some monster pulled a few pads off trying to replace home button zif connector. I started scraping to see if I can follow the traces. They are not clearly seen through the mask like I see some show. Didn't want to start tearing all the mask off, and figure...

FlexBV has done me well. Worth every penny. Had no use to change so far.

I'm killing myself looking for 0201 fast fuses (example 32V 6A) So we have some secret place to buy these for back light repair on motherboards ? Like looking for a unicorn so far. Or better yet, a fuse kit with the 0201 and 0402 ? Thanks in advance !

Yea, I sacrificed a charger, but I'm sure you can find leads. Quick search of ebay pulled them up.

Is the above what we were looking for ? Newish to this, and yesterday was not a good example .....lol

Ok. I must need a few more days off... Using Pos on ground in diode. Power Disconnected. Third times a charm 2 : 0.434 V 3 : 0.434 V 5 : 0.626 V 6 : 0.617 V PP3V3_SUS 3.34 V

Diode Mode : 2 : Open 3 : Open 5 : Tone 6 : Open PPBUS_G3H : 12.59 ? Taken @ Q5400 Pin 4 and R7005 Should be 3V right ? PP3V3_S5 : 3.34V

Ok, think I had something wrong? Ohms by Pin : 1 : 0.5 2 : 9.8 m 3 : 101.9 k 4 : 0.5 5 : 99.5 k 6 : 219.0 k I'll check the rest of the items now.

Very sorry, was forced off the job and then the holidays.. Hoping you had a good one. For Q8002. this is what we have. Pins: 1 : 0.0V / 1.0 Ohms 2 : 0.0V / 8.0 Ohms 3 : 3.31V / Open 4 : 0.0V / 0.4 Ohms 5 : 0.0V / 47.6 Ohms 6 : 3.2 V / Open Again sorry for the delay, and thanks for your...

Oh and a follow up. Pin 30 on keyboard connector J4813 actually does get 3.34V from Q8000. However after about 30 seconds I lose it . Board is out of unit (Breadboard). Not sure if that's normal, but didn't want to leave that info out.

Thanks for the quick replay ! Ok, hair confused. I see Q8000 as a 6 leg chip on the board. However the schematics I see it portrayed as 4 legs, 1 on top and 3 under. So I posted what I see and tested from both views. Q8000 Actual Photo of board has Ohms as well as voltage (Board out of...

MacBook A1398 board 820-00163-05 Had a short to ground on C7324 PPVIN_S5_HS_COMPUTIN and not allowing unit to boot. Replaced the capacitor with Tantalum Polymer 16V 68uF 2917 20% ESR=50mOhms. System boots up to desktop and I'm thinking in good to go. Not so fast. No keyboard or trackpad...

Any way to find what other boards are compatible for parts ? Cheat sheet somewhere ? Sorry, lots of questions....lol
