So with R7050 off the board, F7040 on the board and no U7000 I get OL on all pins except pin 1 which is 144ohms. With R7050 on the board it is 144ohms across all pins.

Appreciate the reply man. Yes 2936 is what I meant sorry. After I made the mistake I took those measurements. I have pretty much given up on this though, it's a mind fucking rabbits hole I've concluded. U7000 isn't even on the board, neither is C7050, R7051 or R7052. R7050 is also off the...

I think it should be about 3ohms shouldn’t it?? Anyway its a piece of shit this thing. Pin 2 R7052 beeps to ground. Removed R7050 and pin 4 still beeps to ground. So CHGR_CSO_R_N goes to ground yet R7052 and R7050 are off the board. U5420 isn’t on board so how on earth does it connect to...

Ok sorry the delayed reply, this got pushed to the side seeing as though it’s a personal goal. Understand the smc reset L now. My understanding of it was reversed. So made a mistake. Went to measure resistance of pin 17/18 of the ISL. Charger was still plugged in and I made smoke.. Pads...

820-2396 has green light. Seemed to of charged a dead battery. Zero evidence of liquid damage. Won't turn on. Ppbus g3h is 12.4v smc_reset_l is high at 3.4v im guessing this is why we are not turning on. I tried shorting it to ground as I assume that would be like doing an smc reset but no...

Yes a mouse lights up, always wondered what that suggests as I've seen you ask that a few times before. Lcd was smashed

ok been working on this 820-00163 for a couple days now. It has orange and green lights on charger. fans spin but no chime and no display. Have checked with working display just in case it didn't chime or something in this model. History is i I replaced the display 12months ago. It has now...

Was only no backlight but problem solved. I came in with a fresh mind and fresh eyes this morning. Spent 2 mins looking, changed the LCD cable and problem solved 15min total. Spent a good two hours last night testing and changing crap...

Need some help please sorry.. ok so pin 1 at LCD connector I have 0v U7700 has pp5v__s0 going in. Ppvin_s0sw_lcdbklt_r is present going into u7700 and q7700. lcdbklt_sw is missing along with ppvin_s0sw_lcdbklt i have replace q7700 and reballed a used u7700 from donor board. Could the u7700...

Firstly does anyone have schematics for this model iMac? I can't find anywhere. Does anyone know the diagnostic leds mean on this model. I have the bottom one on, the next one up flashs on button push and the rest don't light up. Imac does not boot. Have gone though board, no liquid damage or...

FUCK!!!! Disregard this sorry. Made a fkn stupid mistake need to open my eyes and plug keyboard connector into keyboard for fuck sake.

Hi Duke.. So I replaced the LCD today on the 2015 12in MacBook. Forgot to plug trackpad to motherboard in. Opened it and did it last however battery was still connected and I made smoke. Trackpad would then get really hot. And there was a burn mark on trackpad motherboard flex cable. Took...

Must of been the ic because I changed as well and there was small corrosion around pin 17 and r7202 had a hole in it. The problem 100% was fixed after doing so anyway

Problem solved. Ppbus_s5_hs_computing_isns line was not being created.

Looking for help here. Works perfect until lid gets closed upon which I guess an smc reset keeps happening. When the lid is closed for a short while you hear the chime and it reboots and either comes back on or stays off. Then power button to get going again. Sometimes I have to do another smc...

Fixed! C7095, replaced and charging and back on!

lol thanks, believe me when I say I am trying!

ok so I measured in ohms on the multimeter, 0.588 pp3v42 is that a correct way to measure? I'm not sure if I have the range set correctly either

Diode mode. Negative on line positive on ground

PP3V42 shows 0.327 L7095 shows 0.327 both sides U7090 is dead then? It was the only water damaged part I could find anyway
