Alright so probably last update. Restorted audio on that speaker I was talking about earlier, the fault was in u6210, took it of a donor board, now everything works as new ? Now when board has been fully restored, I have no more question. Thank you very much for helping me fix this old piece of...

Yes, if I connect left/right speaker to LIO’s speaker connector - everything works. But if I connect left/right speaker to motherboard speaker connector - nothing works (sounds) Also sometime during booting up I can hear some realy faith static coming from that speaker

Okey... so I managed to get adapter to connect MacBook to tv. everything works, tho sometimes, not consistently when I turn on MacBook it goes full bananas ramping fan to max speed and not seeing battery, tho working of a battery... Also left speaker isn’t working, I tested speaker it self it’s...

Just checked PP5V_S3 is not shorted to ground, and still orange light. also I haven’t solder new c4696, since at the moment I don’t have any. Also connected speakers and I can hear chime. But for now can’t test display cause don’t have any LCD connectors (they are coming) tried thunderbolt on...

Sorry for late reply. So I checked everything works on clock chip ? tho found shorted cap c4696, not sure if it’s relevant or not Update, found out that PPVCORE_S0_AXG is shorted to ground More update: just removed that shorted cap, and what you know... a fucking fan spin ??? only thing is...

Nah I don’t get anything on SYSCLK_CLK32K_RTC that comes from u2700. Tried replacing u2700 nothing changed. Previous chip looked clean and all but I tried resoldering it, but as turned out it was literary welded to the board, cause heating it with heat gun @480C for few minutes didn’t do...

Hi I messed up... I checked back everything and it appears 32k clock isn’t present... can it be cause nothing is working?

I have friend who does GPU replacement quite often so I suppose there is no issue with “experience” part (he said boj cost ~25€) And I have some 820-3209 I checked PCH SN and they match so I will try getting it from there. maybe it’s worth first trying to reball PCH? Or there is no point and I...

Yes but in thoery if I replace PCH it has chance to work?

Oh also if PCH replacement is needed, do I need to find u1800 exatly from 820-3208a, or there are compatible chips...?

Soo only solution is to reball/replace u1800? Or there could be dead cap somewhere or something “minor”? oh yes forgot to say, I put back q5040, and everything is as it was before I removed it If PCH replacement is needed, how much does it cost? It’s just I don’t have that high tech to do it...

PM_BATLOW_L - 0,1V with charger + battery Removed Q5040 - no light on charger, Every pin on Q5040 - 0,1-0,3V PM_SLP_SUS_L - 0V

Soo... any idea what’s wrong? Anything I need to look for?

PP1V05_SUS - 0,1V (can’t be present since U7740, C7740, C7741 are missing) No fan spin with battery and charger, later I will leave battery and charger connected for a bit to see if charging is happening. sorry for stupid question, I am used to repairing iPhones, but now my son splilled...
