[SOLVED]820-00138 fans on high

[jgraffis]

I got in a couple of these 820-00138 machines today. They had small amounts of liquid damage around the lcd connector. the board powers on no internal video, fans go full speed. i have the schematic but can't seem to find a board view for this machine. the machine didn't come with the original hdd, so not sure i can even run onboard diag test.

any ideas?

First inspect trackpad cable for corrosion. Correct LCD used? 2015/16 machines are different from all others.

track pad area looks good. i changed the lcd connector just to be sure. and i got video now. is there away to tell the difference in the screens by just looking at the cables? not sure just yet on the high fan issue yet. i put it in uc found a 128gb drive gonna get an install and see what happens. wish there was a way to either put the original onboard diagnostics back on. don't like letting them leave with out checking them out. ill report soon as i get an install on it.

looks like the ultrasonic cleaner did its job no more high fan spin. problem solved
