In Reply to: High pich scream (16khz) on JVC AV-27F702...HELP!! =) posted by Algae on October 30, 2001 at 08:55:03:
Almost all NTSC tube TVs have this behavior. The sound comes from the ringing of the cathode tube. Because of the vertical and horizontal scanning frequencies on 480i NTSC format, most TVs produce a ring at around 15KHz. It's more prominent on some TVs than others.Turning down the brightness helps a little but won't rid the problem. You will have to change to a DTV which scans at least twice the rate, producing the tube ring at 30KHz and above, inaudible to most people.
