    Thank you for your replies. I switched out the audio cable connection for a coaxial connection. That solved the problem. I wanted to use an optical audio connection but I was unable to make much sense of the user guide instructions. None of the optical ports on the back of the unit were labeled tv/cable so I decided to leave well enough alone. Again, thank you for your help.

    Usualy optical signal will output whatever is set to play(audio) and in the amplifier there sould be a ``optical in`` that can be selected(like a video 1 port)

    you should theck if the connetor inside the machine have not been

    broken on the solder side,check by moving the connecters sligthly

    while listening to it(that problem is easy to fix)

I switched out of the audio-out cables from the cable box to the audio in at the Denon receiver and went with a coaxial cable connection. That switch got rid of the hum. I don't understand why the initial connection produced the hum, but the unit is working fine now.

TUNNER BAD, YOU NEED TO CHANGE THE MAIN BOARD OR CHANGE THE TUNNER WITH AN OLD USED BOARD. MAYBE IF YOU OPEN THE TUNNER FIND A OPEN LINE NEAR COAXIAL CONNECTOR.

Check the input selector on the TV, if you have audio only then it is a cable problem,
that means that cables are not connected in the right way.

S video displays, but Component video is intermittant


Shall we assume that the DVD is fine, before addressing the TV issues? Does it work with any other device or component? Seems that if your S Video is clean, then it's just a matter of refining whether your DVD is as well. Check that, and let us know.

Intermittent sound with cbl/sat. Sometimes sound


Your receiver is HDMI version 1.1,1.2 or 1.2a and just don't work with anything to be honest with you. It's an HDCP (copyright Issue) and 5v pass thru issue. and the list goes on. If you can, just run HDMI directly to the TV and optical or Digital Coaxial to your receiver for audio and all will be well again. If you need more help, just post a comment and I will gladly help some more

I am trying to get the volume bar on my tv screen.It works on everything else but not cbl/sat. Receiver is tx-sr606. Thanks


en order to help out here a few questions need to be asked? Is the CBL/SAT connection VIA HDMI? Some HDMI signals will not pass CC and or On-screen display (OSD) via certain video modes. If all is analog video, not a problem, if mixed with component and HDMI and analog, you may experience issues. Let me know your thoughts and the best of luck.

Split screen on DVD player


This sounds like a progressive scan issue (unit in P.Scan Mode) here is a C&P from the manual

Set "Alt Video Out"
Highlight "Alt Video Out", then press the RIGHT button to select
one of the following options:
• S-Video - Select this if you are using the S-Video OUT jack on
the rear panel to connect to a TV.
• Component - Select this if you are using the COMPONENT
VIDEO OUT jacks on the rear panel to connect to a
Progressive(480p) or Interlaced (480i) TV.
• See your TV owner's manual to determine what type of TV you
have.
- Interlace : Interlaced Scan mode will work.
- Progressive : Progressive Scan mode will work, and Video
and S-Video will not work.
• Press the Progressive button on the front panel if you have a
Progressive scan TV only. Otherwise, the picture will be
disturbed.

1 front speaker and 1 surround speaker won't work on cable selection


theres probably a problem with the right channel cable or plug that connects the tv to the reciever, or the tv is set to mono audio.

Picture is of poor quality (wavy)


This may indicate a problem with the RF tuner. When you are using the DVD player is the output of the DVD using the F (RF Coax) Conncetor or is the DVD connect to the TV using the Video/Audio cables (either Composite (Red, White, Yellow) or Component (Red, Green, Blue)). I am do however believe this to be a RF tuner problem. Make sure that the TV is set to channel 3 and the cable box is connected to the TV (set to channel 3). What you could also do is get digital cable and use the video output jack as the input to the TV on one of your aux positions.

I would first make sure the tunner is on channel 3 when using the regular cable box, or if you are using the TV's cable ready features make sure the tunner is working correctly, this might have to be done by a qualifide TV repair person.

I hope this helps
Thank you,
