I also have an EDM-030 with this problem.. It works perfectly fine when I launch music or video apps, but as soon as I run a game,the screen freezes within a few minutes, and then it shuts down a few seconds later. When the fault occurs, I get two error codes via the UART: 808B00FF and 80830018. I've already checked the MOSFETs and capacitors in the APU VRM, and they all seem fine.The thermal imaging didn't show any abnormalities either.I checked the VRM waveform with an oscilloscope, and the ripple is quite large. I replaced the XDPE, but there was no improvement. I noticed that Sony left out some filtering capacitors , there are unpopulated pads on the PCB,I added some extra VRM capacitors, which brought the ripple down,the ripple peak is currently around 20mV,but the fault still persists. However, I've noticed that some games can run longer now, while certain games still freeze during the loading stage. Should I keep going with capacitor replacements? Could this be related to the SSD? I'm not sure what to do next.
