Sound cuts out especially when commercials come on. I turn off receiver then turn back on and the sound is back.

if your saying that overall the sound works just fine but just some commercials don't have sound , this surely is a cause that not all commercials have Dolby decodable sound , this receiver has a dolby decoder inside it , im betting that you use the dolby sound selection most often , a simple test of theory is to select 2 channel stereo sound in set up and watch same commercials if you got sound now there's your problem , I do ask that you not complain to broadcasters of this (they might fix this) as id rather enjoy missing the entire commercial but no sound would be a viable alternative

Yes, electronic components fail with time: switches, especially capacitors, there can be dust or corrosion acting upon connections; really a multitude of age related problems CAN occur. (Not necessarily but can.) The problem becomes cost vs. benefit for repairing and another unit of that age is probably an inexpensive fix.

most likely your samsung has an active search for inputs. normally to solve this problem is to try moving input of hdmi into a different port on samsung reciever or see if maybe your manual states you can shut off this automatic audio switching. what happens is receiver will actively seek another input when sound cuts out like between commercials or movie/commercial because no sound will be coming through hdmi cable for a sec or 2. Read your samsung manual carefully it might state how to get around it but some don't so that's why i say try a different input to see if it will still do it because some hdmi inputs will be more dominant than others or have a longer delay before searching other inputs for audio.

My SR607 also cuts out from time to time. My experience is that this is an issue of overheating, and protection circuits shut the thing down. Once it cools, seems to work ok. I have plenty of space around the unit, but still it seems to overheat, especially when playing hi-def / digital audio material.

I have a TX-SR505 and the same thing has been happening on mine since I bought it. I am also hooked up to a Panasonic Plasma, using the optical cable to the receiver. It's been perplexing me. I have noticed it typically during commercials, not during normal programming. If I turn up the volume on the Panasonic TV, I can hear the audio, so I know it's not a problem with the over the air signal. It must be something wrong with the reciever. Would love a fix to this!

Your HDMI version software and hardware will not work with todays version. The current version 1.3b is what works correctly (so far) IT can be upgraded to todays specs however, it's a preicey task for minimal gain if you are viewing any TV smaller than 50". The human eye cannot see the difference between 720p and 1080p on any TV 50 or smaller. That being said, if your TV has multiple HDMI ports, you can sidetrack this issue by connecting directly from the source, ie DVD, BLURAY, etc. then use optical or coaxial digital coaxial to the receiver. I know it's not the best news!! don't Blame Yamaha! it's been the recording industry and copyright protection issues that have overloaded product with "anti-piracy" software to the point you can't view it!. All receivers prior to 09' have multiple HDMI issues. Also, try setting your receiver to "Auto" in audio and running an analog RCA from the source to the receiver as well as HDMI, it may help, however, analog is much louder than digital, and I'm not sure if you can "offset" the volume level for analog in that receiver's settings. So, when you go to a commercial it could be unbearably more annoying than not listening to the commercial at all! Hope this helps.

HI,
Yes you are right man, this problem occurs only with the cable problem, i can explain you, if there is a receiver problem means you won't get the sound its dam sure,
only if there is a cable problem you will get some noise or sound cut off with the speakers, so you please check the cables properly it will be alright.

If it will turn back on then it is not a simple blown fuse. If you heard it 'POP' then I would take an educated guess and say that the integrated output amplifier module has blown. You could try disconnecting from the power and taking off the lid and checking to see if there is any physical signs of damage, but, unfortunately there usually isn't. Without electronic knowledge it will be difficult to pinpoint and trial and error replacing parts can quickly become economically unviable. Sorry and Good luck.

I was listening to my surround sound when all of a sudden it just cut off with no sound or anything I would turn it back on and all the power would come on and cut right back off again I have an RCA RT2270 would it be possible to get someone to come out and look at it please help

There are two reasons for this. Firstly, the commercial channels are deliberately boosting the volume during commercial breaks to grab your attention. Secondly, the commercials use compressed audio (narrow dynamic range). This often comes across much louder than program material, which is using a wider dynamic range on which you would have based your volume setting. It is noticeable that the BBC are also sending out wide variations in volume at present - Yes it is VERY annoying. Some sort of ALC (automatic level control) is required but this would need to be switchable. Hope this helps.
