Nvidia shield pro 2019

Hi there,

My shield pro 2019 suddenly developed an HDMI issue whereby it will only display at 720p and the audio output is limited to PCM.

I dismantled the device hoping to be able to test the HDMI traces, and expecting to see an HDMI chip of some sort close to the HDMI port but the traces appear to be hidden I think due to it being a multi-layer board and the only chips in the vicinity are a INA3221 voltage shunt (which I am not sure what would be used for or if it relates to HDMI) and a realtek B111H5 HD audio chip. Everything else seems to be covered by EMF shields which are soldered to the board.

Does anyone know if there's a schematic somewhere which identifies where everything is, or can anyone help me identify where the HDMI related chips are on this board?

All of the information I have found so far online seems to relate to older versions of the shield. Thank you.
