820-3208a liquid damage, no light on charger.

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 tv but haven’t got any result. Tho I tried only 1 time.

Of course no short anymore if you already removed the bad cap; you didn't mention that in previous post...
You can now try for external video, if you have proper adapter.

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 100% working, so must be something on a board

So fat tested everything around u6210, nothing is shorted and resistors are okey. Tried resoldering u6210, but didn’t help.
that chip looks all messed up from bottom, but I want to replace it only as a last action. So what should I be checking?

Did you try other LIO board and flex?

 

[BigPersonalety]

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

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 junk, I learned a lot of new things
See you in the future
PS:
I still haven’t solder LCD connector, so there is slight chance after 2-3 weeks I might comeback with some issue related to LCD, but I hope everything is fine in that department... ?
