Lost sound through tv/sat mode

Hi, my system worked perfectly til the power flicked off one day, now my tv will not play through the tv/sat mode but only through the dvd mode where it all still works right. the dvd player will now however not come through the dvd mode at all. i didnt change any wires or anything but i did notice that on the tv/sat mode that i cannot get the tuner to change to digital. it is stuck on analog, but on the dvd mode when i hit the signal select it will change to digital mode and thats when the sound comes through. Can someone PLEASE help me??

Thank you,

    Hi there, tried to unplug for an hour and wait. still the same problem. model is a pioneer vsx d498. It seems so strange that i can get the surround sound to work through the dvd preset now but the dvd will only play through the tv speakers now not the surround sound. It seems like the reason this is not working is because on the tv/sat mode wont switch from analog to digital. i went to best buy saturday and tried to get a brand new tuner to switch from analog to digital and it wouldnt as well. It almost makes me believe it is a setting. I know the wires are all hooked up right because it worked for over a year and i had it professionally installed.

    Please allow me to add another twist to this strange scenario. I now have managed to get surround sound to come through for my dvd player on the cd mode setting. Now mind you, I have not changed ONE single wire and for the last year or more everything has worked the way it should up to when this problem began. This is the strangest thing I have ever heard of. Any ideas on these strange happenings??

Initially, would you pls try a systems reset by removing its plug from the mains for a couple of hours.

Thereafter, would appreciate an update. On your post back, pls provide additional information on the units that are interconnected (brand and model numbers). We will then figure things out from thereon (if required).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    Hi again,

    To my understanding, the Pioneer VSX-D498 will only allow switching to Digital if the signal source/input is Dolby Digital, PCM (32kHz, 44kHz, and 48kHz) digital signal formats. All other digital signal formats other than these, would have to be treated as “ANALOG” therefore the Signal Select should be "ANALOG".

    Perhaps there is nothing wrong with the receiver and as you have posted "it is a setting" as you have tried likewise tried with a "brand new tuner". If so then perhaps you have to consider the settings of the other units hooked up and providing the signal coming into the receiver such as your TV/Satellite Tuner or DVD Player. They have to be specifically set to output/produce Dolby Digital, PCM (32kHz, 44kHz, and 48kHz) digital audio signal formats.

    As initially requested, would you please indicate what other units are hooked up to the Pioneer VSX-D498.

Try unplugging all of the equipment for 30 minute to an hour, and see if this fixes it, otherwise, it sounds like the flickering power may have caused a surge in the circuitry of the equipment, causing it to short circuit the digital tuner in the TV.

You're guessing. That is exactly the wrong thing to do. Get the manual.

"[D]vd 6 channel input" is for a 6-channel analog input as the name implies. I doubt you even have a source that HAS 6 analog channel outputs.

Speakers are OUTPUTS of the amplifers' speaker posts. Any one can work ANYwhere.

And that bi-wire capability, IF the speakers have it - pretend it isn't there.

I have a LG47" tv

Your DVD audio is sent directly to your receiver - not to you TV. That's why you can hear the audio on your stereo. The TV audio is not being sent anywhere - it is "stuck" in the TV and is amplified and sent to the TV speakers. Since the TV speakers are off, you don't hear anything. In order to listen to the TV audio on the stereo system's speakers, you need to send it to the receiver.

You need to have a pair (left + right signals) of audio cables (assuming you wish to listen to stereo sound) from the TV's Audio Output jacks to a pair of Audio Input jacks on the receiver / amplifier. You can use any unused input - CD, Video, Tape, Sat, etc. If you use Tape or Sat audio inputs, when you wish to listen to the TV audio, you must select the Tape or Sat input on the receiver.

Do not send more than one signal to a set of inputs on the receiver. Typically, a CD, DVD and Sat inputs offer two or more of the following types 1) Analog audio. These are the older RCA jacks that have been around since the beginning and require separate cables for left and right channels. 2) Optical inputs. This is the newer digital interface that provides for Dolby Digital (and others) format sound over a single fiber optic cable. 3) Coaxial inputs. This jacks looks like an RCA jack, but usually has an Orange ring - instead of the Red & White rings that analog RCA jacks have. They use a single coaxial cable. 4) HDMI input. This jacks carries both digital video and digital audio signals. If you are using an Optical input for the DVD on the receiver, do not use any other unused analog or digital inputs associated with the DVD to "piggyback" another device like a CD , VHS tape, etc.

I hope this helps and good luck! Please rate my reply. Thank you.

To listen to Tv program sound through your home theater system you will have to connect a pair of RCA to RCA cables (Red and White pair ) from the audio out socket of the TV ( some times three sockets Yellow/Red/White labeled Monitor out. Ignore the yellow as it is video out ) to the Aux or CBL/Sat input of the LG system. Then to listen to the sound through your LG HT system switch the Input selector of the LG to Aux or CBL/SAT. Will work for sure.

My Denon AVR1611 powers up and the TV sound works just fine, but after 5 seconds or so the sound quits and I have to press the quick select sat/cable button to start it up again.

There are two types of input for sat/cable in your amplifier. One is the Digital input and the other is the Analogue input. You didn't specified which one is currently used by you.
However, if you connect the digital input then you have to configure the input assignment to digital and for analogue input configure as analogue.
If you use analogue input and input assignment is in digital mode then the problem mentioned by you can occur.

First of all check the input assignment for sat cable. for that do the following
1. Press the menu button on the amplifier's remote.
2. Select input setup input assinment ( check the input assignment for sat/cable, If you are using the analogue
input select it as analogue,if your are using the digital input then select it as digital.

Hi there, My samsung home thatre HT-BD2T produces no sound ONLY when playing Bluray disc. It's fine with DVD or TV, the sound was perfect. Any ideas? Thanks

Your system is one of the best in home theater systems but the down side of that system is that it's only Blu-ray Profile 1.0 compliant, so it will not play some bonus features on some new discs in 2008 and above, I don't know if you have tried other blue ray discs but if it still has the same problem, it'll show a problem with the system not being able handle to deal with codecs so I recommend calling Samsung and having them fixed or replace the unit. they only thing you can do is "cold boot" it and see if it helps. Have a look at it and let me know if you need more advice. Best

No sound from left fronts (A+B) in TV mode.

Just check the rca cables. Try wiggling the cables as well. If they are the plastic rca cables, they do to wear out quick.
If it is not the cables, than it is a shorted resistor in the channel sound output

This is most likely a problem with the processing chip/system. It could be as simple as a bad connection at the chips or the chips are having problems internally. This is not a problem that is likely to be fixed without bench time and test equipment. You're going to need to get this unit to a service shop for proper diagnosis.
