Hi there,
I have the same problem. I have a PlayStation 5 with an EDM-020 board. The issue was that the HDMI port was defective. I turned it on beforehand to see if it would still work. The PlayStation powered on, but there was no display. I couldn’t test it further. I replaced the HDMI port, cleaned it thoroughly, and refreshed the liquid metal. After this, I tested it, and the fan immediately started spinning very loudly and shuts itself off. Now, I can sometimes get it to turn on. As long as I stay on the home screen, it works fine. But as soon as I start a game, the fan spins extremely fast, and it shuts down again. I used a thermal camera, but it doesn’t show that the board is getting too hot. The hottest point is 50 degrees Celsius. Does anyone have any idea if this could be a problem with the temperature sensor?
Tnnx everyone for reading and helping
