Playstation 5 EDM-020 board. Most rails test good, first stage has good 320mah current draw. Testing voltage rails around the console, I see that the 3.3 enable at the encoder power circuit is missing and therefore 1.8 and .9 is missing for the HDMI encoder, but all other rails seem good. SBV IC near f7502 is outputting low at a little over 2.05v. Resistance on the circuit measures around 350 kilo ohm. Uart code 80810001, general apu gddr6 power failure. Any suggestions? Calvin?
The output at the SBV chip (IC7113) near F7502 is 2.08V_MAIN. So 2.05V are ok.
Can you post the whole UART error code string?
