My RD-XS34 supplies sound to the TV when playing back a recorded source from the HDD or a DVD, but recently it does not play any sound while in TV Guide. It shows the tiny picture of the broadcast program in the upper left corner of the screen as always, but with no sound, AND it plays neither sound nor picture when changed from TVGuide to a selected channel.
And, here's the additional variation, there is a picture from a broadcast program if I stop playing a recorded source and it "switches" to a channel, but still NO sound.
I have checked settings, etc. with no solution.
Any suggestions would be helpful...
