RE: Pioneer DVD System HTZ
-575DV NO SOUND FROM RADIO
I've just spent 20 minutes @ http://www.pioneerelectronics.com/PUSA/
and let me tell you I am not impressed! I saw a lot of links to order repair parts and/or repair service plus the site was very slow to react and gave me an error on downloading the manual!
ANYWAY....I was trying to find out, unsuccessfully I might add, if your Pioneer DVD is also a recorder! Is it?
I have an RCA 500 watt Home Theater
and I can sympathize with you on the complications of the remote!
I know with my system the DVD can be playing but muted while I listen to the radio or the radio can be muted while listening to the DVD.
MAYBE you muted the radio when in the DVD mode so it may be as simple as going back to your remote getting in DVD mode and un-muting
the radio as your system may be storing the mute in your remote even when you unplug the reciever!
I'd try taking the batteries out of the remote for at least a minute before doing anything else.
Hope This Is Helpful!
