My ReplayTV 5060 has stopped outputting audio just over a year after purchase. The video is fine but there is no audio on replay or live TV. I am using the component video and the RCA audio outputs. There had been no connection changes made to the 5060 audio/video system when this problem first appeared. I have tried moving the audio outs to a known good audio input on the receiver with no change. I have also done a “hard rebootâ€. It appears to me that the RCA audio driver has failed. Is there anything else I should attempt? Any idea what the cost to repair the audio driver would be?
