Have recently bought a Phillips TV, linking to 4 year old Marantz nr1506 AV Receiver (Blu-Ray + Virgin V6 as inputs in AV receiver) and getting all kinds of issues with sound or picture not coming through. Ran Firmware updates on both. Best way to resolve appears to be by unplugging the AV receiver and plugging back in again. Considered replacing the HDMI cable between TV and AV, but haven’t done that yet. Any suggestions appreciated.
