820-4924 Liquid Damage No Boot

Board came in with liquid damage around CPU mosfet and Q7630, Also burnt pins in the Thunderbolt port.

Removed and cleaned up the CPU mosfets and Q7630. Cleaned out the thunderbolt ports and It has green light switching to Orange.
Fan spins in SMC Bypass and spins in normal boot once the cpu get warm. CPU gets warm but not hot. Backlight turns on and I have LCD Power but I have no image and no chime.
Does not output anything on HDMI and does not boot to USB.
CPU mosfets both show correct power going to CPU when backlight is on.

Is the Intel chip dead on the GPU side or is there something else that may cause these symptoms.

If there is backlight most things are working. Can you do a PRAM reset on an external USB keyboard? Disconnect the trackpad to prevent the internal keyboard from messing up.
