Sony Sony STR-AN1000 7.2-Channel AV Receiver with Dolby Atmos HDMI HANDSHAKE Error Fix: HDMI Authentication / Handshake Failure

Error code HDMI HANDSHAKE on the Sony Sony STR-AN1000 7.2-Channel AV Receiver with Dolby Atmos means: HDMI Authentication / Handshake Failure. Connected HDMI source devices produce no picture, no sound, or the picture displays as snow, a black screen, a purple screen, or a frozen frame when routed through the receiver. HDMI handshake failures occur when the source device, receiver, and TV cannot successfully negotiate the correct video resolution, HDR format, color space, or HDCP content protection level across the chain of devices. Power cycle all three devices in sequence: turn off and unplug the TV first, then the receiver, then the source device; wait 30 seconds; then power them on in reverse order (source, receiver, TV). Try connecting the source directly to the TV to verify the source device works independently. In the receiver HDMI settings, try changing the HDMI Signal Format, 4K Output, or HDCP mode for the problematic input port. Ensure all HDMI cables are Ultra High Speed rated if using 4K HDR or 8K content. Update firmware on all three devices.
