[Donlan78]

working on 820-01700 2.4,64,8tb,5600m great specs, and great condition, board is clean, no liquid damage, all ports amp meter just cycle on off wont even display voltage, just lights up and goes back off, looks like 5v .3 amp on all ports all cycling after 1 sec

Check diode mode to ground on CC1/2 pins of all ports.
Also check the same at R7020 and F7000/1.

Don't you find "CC1" and "CC2" on schematic???
Shouldn't be dificult to find them around CD3217 chips.
