Chosen Solution
I recently replaced the PI3USB chip because there was power, but no video/audio. Replaced the chip, everything works great, however now when I place it in the dock the console doesn’t show an image on the TV, but the led is solid green. Any ideas?
I too have this exact same problem, I purchase a faulty switch from ebay and replaced the p13usb chip and the switch works perfectly now in handheld mode but will not dock, my next option is to replace the USB C port as I have seen this done for other issues and wondered if it may be a faulty connection to one of the hidden pads underneath. But as the switch is working I am reluctant to replace it at this stage, especially with that awful screen connector, nearly bent a pin the last time I had it apart
