820-2936 not turning on

[iClub]

Some signs of oxidation in the u2600 region.
Voltage: PPbus_g3h 12.60; pp3v42_g3h 3.43V; PP5v_s0 0v; All_sys 0v; PLt_reset 0v; pp3v_s0 0v

Replaces u2600, but PPVRTC_G3H stands at 0.78V.

So you have short; cannot expect to start the board.

" Replaces u2600 "
Did you really replace the PCH???
Or was U2800, maybe...
