OK started with the buttons on the side needing to be pressed really hard, then when you turn the power on no controls respond for 60 seconds via buttons or remote, later I tried to plug direct into cable and scan for channels, but it scans analog fine and hangs on digital, progress bar never moves. Now some channels are fine, some not as clear, and some have volume 1/2 second then silent. these silent channels are not all low signal, some are crystal clear. I'm using cox cable in RI and the loss of audio is a new symptom while still on cox, was working days ago. Son has a sony upstairs with no issues, brought down here and all is fine. Figure I probably need a controller board and maybe a main board. any ideas, get really nice picture with what I have, hate to waste. runs really hot
