3 PS4 slim in the hope that I can repair all three so I can sell two and have one for free.
All three had the error that no picture is outputed but the LED lights up white.
I have already replaced the HDMI encoder IC and one PS4 is working straight away.
It seems to be a different error with the others.
I have measured everything that I can measure in the installed state. There are 5V, 5.1V, 2.4V, 3.6V, 1V, 2V. I can't see any differences between the working PS4 and the defective ones.
I have measured the HDMI port and all PINs have approximately.
