Help! popping noise when changing channels

**pengwin** · August 24th, 2004 23:58

I have recently started to put together a Home Theater system. I am using a Yamaha HTR-5660 receiver with Yamaha NS-777 speakers. I am using an AKAI TV. I just hooked everything up and all are working fine, however, when I change channels now I get a solid pop noise as the channel switches over. When the TV is on using only the built in speakers, it does not pop. Only pops when I have sound directed through the receiver. Very annoying.

Any help on cause, and solution, would be much appreciated.

Does your TV have both fixed and variable audio output (RCA)?...if so, you could switch to the other option to see if it continues. I've never experienced the problem with my gear that you have...??? I'm clueless.

oh yeah, welcome to the forum.[IMG]'/idealbb/images/smilies/1.gif'[/IMG]

Welcome to the Forum, John.

I think Dane's on the right track. It sounds like whatever input you have into the receiver is set way too high. How are you feeding the audio signal into the receiver?

TV out, cable, dish? If it is one of the the latter two, they should be set at fixed, not variable.

Let us know.

Thanks for your help.

My TV is definately my weak link at this stage. There is only one set of RCA output jacks. This is how I am feeding the receiver. I am assuming that they are fixed as changing the volume on the TV does not effect the receiver/speaker volume.

I also have noticed that when the TV is turned on there is a period (1 second or so) where static can be heard before the sound kicks in. I know that there is dead sound time between channel changes, but why would it cause the pop?

Appreciate the welcome.

John,

I''m a newbie too and have a similiar problem with my Pioneer receiver with DD 5.1. I have my DIRECTV connected through the receiver for all my sound, nothing through the TV. Whenever I change channels, loose my dish signal, or toggle between SAT, DVD, or radio modes on the unit, my center channel has the same type of popping sound. I assume something bad happened to the enter channel circuit in the receiver (pretty bright on my part[IMG]/idealbb/images/smilies/1.gif[/IMG] Since my speaker is nothing special and the receiver is 5yrs old, I''ll just sit it out until I upgrade.

Sorry I can''t help, but misery loves company. I''m sure someone around hear has a solution for you,
Kev

You are correct, misery loves company.

I ended up getting a second cable box and routing sound direct out of the cable box. When changing channels through the box the sound is gone. I have a feeling that, in my cae, it is the result of a cheap TV. The sound is caused by the dead signal between channel changes. It may be that the output signal from the TV is too high and thus the "pop", or it may be that there is a more lengthy lag time on a cheaper TV? In any event the cable box fixed the problem.

Thanks for your support.

You're Welcome John.

I�m a little confused as to why you need a second cable box. Can�t you just use the audio outputs on the first cable converter? Most people suggest video, box direct to TV � Audio, box direct to receiver.

Kev:

Welcome to the Forum !

Yup, sounds like your receiver. Time up grade ! [IMG]'/idealbb/images/smilies/9.gif'[/IMG]

Do a search for receivers in the HT & audio sections. I remember a �Cheap receiver� topic that had a lot of responses.
