Hello. I have a problem with a PS5 console that I bought to learn electronics repair. The auction description indicated that the console had been dropped. The HDMI port and USB ports were damaged. The HDMI port was replaced by the previous owner, and after his repair, the console worked for 2 days and then became dead. After receiving the console, I replaced all the USB ports. After replacing them, the console started to turn on. On the logo screen, it displays "too many USB devices connected". My further attempts to fix the error involved replacing the Southbridge, 4 TPS2001D chips, and the Wi-Fi module. Unfortunately, the "too many USB devices connected" message still appears, which means I can't synchronize the controller to start the console. I would be very grateful if you could point me in the direction of where the problem might lie. The mainboard is EDM-010.
