How do I connect Samsung smart TV to a Yamaha receiver and get sound to come out of surround sound speakers?

Generally you will connect the Digital audio or optical audio cable from TV to the input of Receiver. Then using the remote control of Receiver you will program the source for digital audio or optical audio as TV. I am assuming the speakers on the receiver are already connected and working. All you do is then turn on TV and turn on Receiver and select TV on Receiver. The TV audio will play through the receiver. Make sure the TV sound is in Mute.

I have a Denon Surround receiver, model AVR-1804 which manages our home surround sound system (6 speakers including a sub-woofer). When the TV (Visio HDTV) is turned off, but the receiver is still on, we...

Some kind of ground potential difference between the TV and the AVR or perhaps it's a badly shielded cable.

Considering the multitude of variations you may have connecting the TV video and audio to the receiver it's hard to pin it down, but try removing all cabling between them and that should silence the hum. Add any cable and see if it comes back. Disconnect it. Test each cable the same way. At some point a single cable might be implicated. Replace it.

Also consider routing of any analog audio cable near power cables, the TV or other sources of high voltage and magnetic fields. I have a known problem when my overhead dimmer-controlled track lighting is on. Food for thought.

Subwoofer hum from STR-DH800

That points pretty much to a bad shield on the cable. Have you tried another one? Another thing to try is to rotate the AC power cord on the sub (if it has one). Sorry, too lazy to look it up.

Digital optical output for technics 5.1 surround sound receiver

I went to the HDTV plasma manual. It stated the only way the digital optical audio output would work (from this TV) was to go to the menu, select audio and turn off the TV speakers. Basically, it had nothing to do with the technics receiver.

Humming sound when watching tv,but not when watching dvd's

It wounds like you are getting interference from you tv to the receiver. You can try a few different things here.

1. Connect the tv output into another input on you receiver to see if it isnt the channel on the receiver.

2. Try a different set of cables between the tv and receiver. Faulty cables can give you problems.

3. Connect the cable from you tv to a different device. (another dvd vcr blue ray etc.) This will tell you if its the receivers or the tv.

I have a Vizio 42' and a cable box and there's a constant humming

I think I had the same problem. This is how I fixed it.

I have my vizio 42 hooked up to a Harmon Kardon surround sound, and the digital cable box. Essentially, I can adjust the volume 3 ways - through the tv, cable box or av receiver. The humming sound happens when you have the volume maxed out on the av receiver and not the cable box.

For example, the sound level on my Harmon Kardon goes from -10 (lowest) to 10 (loudest), with 0 being the middle ground. The buzzing was happening when the Harmon Kardon was set to 10, and I was using the cable box volume to adjust the sound. To fix it, I turned down the volume on my receiver to 0, which may be about 50% max volume of the receiver. Then, I switched devices and used the volume on my cable box. This got rid of the static I was getting. Hope that helps.

Surround sound 5.1

Does your rca cables go to a surrond sound amplifier or directly to the tv. The tv only has two speakers.If the signal is sent to a seperate receiver it must have a lisyen mode then set to 5.1 surround. The digital optic cable should go to receiver first.

Good Luck

Purple and Green hum bars?

You could have a drain on your AC (120) causing the hum bars in your set . Best thing to try is to reduce what you have plugged into your 120v outlet . One of your unit could have a capacitor going bad in its power supply causing the hum bars . Even if it is not turned on. Try one unit at a time . if you find out it one of your units they make what is called a line conditioner which filters out these hum bars . Good luck
