HD56W58 rear projection tv started snapping and popping with a high pitched squeal then went dead

Our TV started making a popping and snapping sound along with a high pitched squeal then went dead. I turned it off and it smelled hot then it turned itself back on and continued with the noises. I had to unplug it for fear it was going to blow up.

Same problem, high pitched noise over regular sound and no pictur


No guarantees with this diagnosis. But it sounds like an HT ( high tension) leak This is often caused by the lead becoming partly unplugged ( being bumped or moved) and because of dust buildup it arcs making a high pitched hissing whistle.Ther lamp may also have been affected by the HT leak. The safest option for you is to call a service technician to it, as opening it up could cosntitute a a danger to the unskilled.

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.
