SOURCE: No audio on pasma when cable set box set to certain channel

In that case two things might be happening. 1. HDMI/DVI cable you using might be faulty you want to change that or 2. The HDMI input of your TV set might be the problem. I will suggest you use component cable instead, I am talking about the 5-color-coded (green, blue, red and red/wihte) cable to connect the set top box to your TV.

WD-65734, cable DVR, audio receiver and digital remote: picture goes black for 1-20 seconds and then returns, but audio is stable. Status led and lamp led are NOT on. Any suggestions? Thanks,


well are you using an hdmi cable, cause if you are there is a known issue with the communciations where it will lose communication if you reremove the hdmi cable then turn the box off slide the cable back into the box then turn the box back on it should restore the pic and audio just fine. if this is your fix then its one of three things a faulty hdmi cable or an out of date hdmi cable meaning the version is no longer support for the video production. or it's the hdmi output on the cable box. or it's a poor seat/faulty hdmi input on the tv. easy fix is try to replace the cable or use componet cables (red/blue/green) if this is not the setup of your tv/cable box then i will need more info.

I am having problems getting cable on my TV. The cable man told me on the phone to change it to either #4 on the back of my cable , and then the cable will work. The problem I have is when I look into the...


There are several possibilities here Brenda. If you have a cable box, then the signal is coming out either as component (5 individual connections of varying color) or High Definition (1 cable that supplies both audio and video). If you don't have a cable box, then the cable runs directly into the back of your TV. This is calle da coax cable. Either way, each "input" on the back of your tv should be labeled as a number. Take note of this number and Once your TV is turned on, locate the "Input" or "source" button on your remote. This will allow you to switch which device you would like to view on your tv. If you have a DVD player or gaming unit hooked to the tv, this is how you would choose to display it. Once you've chosen the correct input number, you should eb able to view cable. Hope that this helped

My (Cable Service) wire feed is directly behind my HDTV and hooked up over my fireplace . The Rxv667 is located on a side wall book shelf. I have A HDMI wire running to the TV from my receiver. Do I need...


Is there a set top cable box, or are you feeding the cable directly to your HDTV (coax directly to the TV). If you are feeding cable directly to the HDTV then you don't need HDMI. There maybe exceptions, but most TV's don't have HDMI output. The only thing you need to run from your TV to the Yamaha is an audio cable. I assume your HDTV has an optical audio out (either TOS or coax.... Your Yamaha will accept either). Connect the optical audio cable to the AV4 input on the Yamaha. This way when you hit the TV scene button on the Yamaha remote, it will select the AV4 audio input (the default for the TV scene). The optical cable will feed the full audio signal, so that the Yamaha can pass through the surround sound or use the decoder as appropriate to feed your 7.1 or 5.1 speaker system.
If you have a set top box, you may be better off moving that near the Yamaha. In this case, cable goes to settop box, output of set top box via HDMI or component video (RGB) and optical audio to the Yamaha (if you use HDMI Input 2, and AV4 for the optical audio (if necessary), the TV Scene will select the appropriate inputs) and then an HDMI to your HDTV.
In case one, you may need to setup the TV to process the audio appropriately. I have experience with Panasonic Plasma but thats about it.

I can't get my back speakers on when I'm watching TV in HDMI. I have a new TX-SR608


What is feeding the video/audio signals to your Onkyo receiver? Are you getting your input from a satellite receiver or cable set top box? Or are you just using you TV with a coax feed from a terrestrial aerial?

You need a receiver that will decode Dolby 5.1 or 7.1 if you want to use surround sound. If you are using your TV as the reveiver and it has that capability then the problem is probably the type of HDMI cable you are using. You need a cable that has 'audio return' - in other words it will feed the digital audio (from your TV receiver) to the Onkyo box. Some HDMI cables do not include 'audio return'.
Check what type of HDMI cable you have.

If you respond with answers to these questions I will be glad to provide more assistance.

I lose Audio from internal speakers Vizio


This issue is actually caused by my cable box. Access the audio SETTINGS on Hand held Cable Remote, and turn on the HDMI and or "Digital Audio Out" option. found on 'more' settings list. This should fix the issue. I had assumed the Cable companeis 'Boot' would have installed this feature during its initialization.

I recently purchased an xbox, but because of the cable box, i dont know to to get video


Your cable box and TV should have RCA input jacks (Red, White, and Yellow) Red & White are for Audio and Yellow is for video feed...

HD Receivers & HD TV's are just slightly more upgraded with better video feed connections.
HD video can use three color coded RCA jacks for the video feed or a HDMI cable; if you can use the HDMI connection on your TV I recommend using that because it's less confusing to plugin the input cables. Try turning your TV to it's side to see what inputs you have available to connect your device to.

After you have it pugged your device into the input jacks press the "Input" key on your TV remote and power up the device.
Most TV's have more than one input, so you may have to cycle through the TV inputs by press the input key again until the video feed is displayed.
(If you don't have a "input" button on the TV or remote control you can try entering channel "00")
