High Pitch Sounds


In this model the horizontal drive coil vibrates and makes a high pitch squeal. Most times it is intermitent. Touching on the coil with something (non electrical, like wood) will make it stop or change it's pitch. The fix my shop uses: It's not to technical, but, we put fingernail polish around the coil. It's a remedy I've used for decades and has always worked. Some shops use a hot glue gun. With the back open you can hear the coil to locate it. When fixing the problem have the set unplugged. When a technician is working on a television while it's plugged in. He uses only one hand and stays away from the high voltage.
