On/Off Beep. Shorts around APU test points

I have an xbox series x that does not power on. It started as an HDMI repair with ripped traces and snowballed into something worse. I cannot get it to come on. I ordered a raspberrypi pico to flash this firmware (https://github.com/xboxoneresearch/PicoD...) and get the whatever POST code it was throwing.

The result was SMC (1): E006 [SMC_FATAL_CPUGFX] Low priority: VREG_PWRGPAB_CPUGFX_PWRGD missing/timout: Check shorts on V_DRAM1P8, V_SOC1P8, V_SOCPHY. U681, U7, U129, U57 and U480 drive this signal low when a fault is detected.

I checked those test points and got no shorts. I did get shorts on the V_GFXCORE, V_CPUCORE, V_MEMPHY, V_SOC test points though.

I am at a loss as to what could be the issue here. Can anyone guide me in the right direction?

Hi!

Did you also checked the MOSFET? It does sound APU related anyway, but maybe you can check that one out as well?
