Why does my sound system pop when I switch channels with my tv remote?

If this is a Surround Sound System you can check channel and audio tone levels using the remote. Check remote for a receiver button followed by Test button. Check manual for test instructions.

It sounds that the main system control memory IC is faulty. Replace it and check. It is a very small IC, having 8 solder terminals, and can be located very near to main system control IC. Will look somewhat like this.

It's not going to be the mute feature as the sound works on video. Tuner may be damaged? Could be the channel?

You can program to regular (analog) antenna channels. To do so you must use the original remote which has a TV/DTV switch in the top right corner of the remote. Choose the appropriate mode for the type of channel you want to see or scan for. Here is a link to the owners manual and a picture of the remote swithc. The info on the signal switching is on pg.13.

you could do it to setup to a/v input . then try to set up to menu to do setup.if not . you tv need change epprom ic. good luck!

You can access the menus using the buttons on the set. Go to audio menu, you'll find a setting that says listen to and have choices of mono stereo or sap, choose stereo.

I had this same issue, and solved it by putting the TV in "Theater Mode', which can be acheived by hitting the "Theater" button on the remote.

install your cellphones with tv remote.. download that from www.mobile9.com.. you can use that to remote you TV.. depends on your cellphones..

sounds actually like it has had weather damage, sometimes water can get into a place it shouldnt on a tv, not shorting it out, but instead messing up in your case the numbers or menu screen, so i'd say it is best to take it to tyour nearest recycler, hope this helps.......jason

This noise is normal with the cable box unless you set the cable box on HDMI sound
