    Somewhat the same problem with the 52".  No sound from the TV speakers - works great with receiver however, nothing from the TV.

    The TV is on "fixed" - is not muted and the sound is up.

    Any suggestions?

No reason for the audio not to work on the RF cable. Check under menu and option and make sure audio is set to fixed and not variable.

How do i turn the captions off on my sharp aquos 65

It depends on your connections. If you have a an antenna, standard cable from the wall, or a cable box connected with a coax cable u will have to turn it off using the CC button located under the panel on the bottom of you aquos remote. If your cable/satellite box is connected any other way besides coax, u will have to turn off the closed caption using the remote for that device...hope this helps.

Set up

The specs I am reading online are saying that it has digital coax connection. If your hooking up hd cable or hd satellite box some of those have a digital coax output on them. If your hd cable/satellite box only has optical out the system you have says it comes with a optical to coax converter which is pretty cool. So you should definately be able to hook up that sound system to your cable/sat box digitally for best sound. The only other way would be to run stereo red,white cables from your cable/sat box to your stereo as a last resort.

Turn off closed caption on input(component) on Sharp Aquos 42"

I have a Sharp Aquos 46" and go a Comcast HD receiver as well, and had the same problem turning off the Closed Captioning. I order to turn it off you need to go into the box user setting by (starting w/ the cable box and tv on) pressing the power button for the cable box then the menu button for the cable box. This will open up the user settings menu. Just toggle CLOSED CAPTION to DISABLED.

Connection problem

The best hook up for this unit is to use the hdmi if your samsung box offers hdmi output. The panasonic vcr should be hooked to any one of the composit video inputs with the yellow video cable and the red and white audio cables. If the vcr does not have composite output then use a rf (coax cable) to antenna a input and put the tv on channel 3 or 4 as vcr is set for.

Sound, but no picture

The hdmi inputs on this unit go directly thru the main digital pcb. and the component inputs feed thru the av pcb then to the main pcb. If the composit hook up do not work and hdmi inputs do work the unit has a bad AV pcb.

How can I take advantage of digital cable?

No digital sound comes from Digital Coax or Optical and in order to utilize a digital signal u need HDMI or Component although component wont be truly digital. Try running everything to the TV then the sound out of the TV into the sound system. If its a high def source like high def cable box then use the optical conection on the back of the aquos and plug than into your surround system. if ur system doesnt support Optical or digital coax then you need an updated surround system. If i misunderstood your question im sorry. If u live in CT though stop by Circuit city in North haven. either myself, Dave, or my associate Justin should be able to help you out. and dont worry we're not on commission or anything.
