| Hi Crosscomp, There might be several reasons behind the problem you are facing with your TV Audio. * First check the options, should be in Menu>Options>Audio, look for audio system profiles, try changing them to see if anything happens. * Connect any audio/cd/dvd player with your TV and play something to make sure if the problem is related to tv stations only or it happens to all. * There is a possibility that your speaker carbons are busted due to high volume. It makes sense because you only get that "high pitched whine" with high treble, it seems carbons can't vibrate to make proper sound but the wire coil makes noise due to high voltage. If your problem is not solved yet, consult a electrician to be sure, we only can make assumptions without testing the real thing! Goodluck, hope you will get it fixed. |
