The receiver powers on, firmware has been updated, has been factory reset, and looks great with light signs of use. Tested the audio via bluetooth and all speaker connections work fine. However, there doesn't appear to be a signal from the HDMI port, so nothing shows on screen, and there seems to be some kind of software issue as switching between different sources etc seems a bit laggy. For these reasons, the reciver is being sold for parts, as is.
