Liquid on a few spots. J4800, U5110, some around SMC as well. Replaced J4800, touched up SMC area as well as reflow and touched up 55110 area. Replaced I/O Board and cable, as well as TP cable. Fans still high. Ran Apple Diags and Im getting SMC error and Camera error. Fans high with or without camera connected. Any direction will be appreciated.

Thanks

Ambient Light Sensor uses same camera connector.
And ALS is connected in the same bus with various temp sensors...
Try a complete LCD assembly, to discard ALS.

Hi!
Sorry for the delayed response, I got sidetracked and just got back to this one.
I tried the full display assembly with the same result. HWMonitor showed that the issue was with CPU Sensor. SMBUS _SMC_SDA was fluctuating. Followed that line to U5620, where there was a tiny bit of corrosion that I missed. Replaced U5620 and all is good.
Thanks alot guys for your help!
