Hello,
I have an Anthem MRX 520 AV Receiver (AVR) with current Software/Firmware updates completed. The AVR was experiencing fluctuating signal loss when watching Bell TV and the Nvidia Shield. The AVR suffers more “no signal” than operating as it should. It also experiences speaker interference (popping/crackling noises occasionally). Radio/FM works fine. The equipment I’m using with the AVR is a Panasonic TC-65DX900 TV, Wharfdale Diamond 9.5 speakers, Wharfdale 9.CM center speaker, Klipsch R-12SW Subwoofer, Bell TV Box, and a Nvidia Shield Box. I sent the AVR in for repair and was advised a new HDMI board was required. $585 for the board and $160 for labour. I declined the service, however, they sent it back with a different board that would allow audio to function via toslink/fiber optic. BTW HDMI ARC and HDMI 2 and 3 work with video but no audio. That service cost me $260 which included shipping. It worked for a few days and now has no signal. The connection setup is TV Fiber Optic out to AVR Fiber Optic in (number1). Bell Box and Nvidia Shield connected to TV inputs 3 and 4, not HDMI ARC. AVR to subwoofer and speaker connections. I have called Anthem and have not received a response in a few weeks.
Any help or ideas would be appreciated.
Thank you in advance
