Question about Sony FD Trinitron WEGA KV-27HS420 27" TV
When the TV is on I get a high pitch sound. I turn on the volume mute and the sound is still on. I turn off the satillite and still have the pitch sound . The sound is very, very annoying and sometimes hurts my ears. Any ideas or is it time for a new TV. Picture is still great!!!! Thanks Dunovan
The high pitch squeal you hear is usually caused by a coil vibrating, normally in the horizontal circuit. I've also seen the ferrite bead on the horizontal output transistor do this, but, it is rare. I normally will repair this by finding the coil and "tightening" it. To tighten a coil, technicians use different chemicals, such as, a hot glue gun, rubber silicone or even finger nail polish. I will find the coil that screams by starting with the usual suspects and using a wooden dowel, barely touch the coil and if the pitch of the noise changes, then, thats the coil that needs repaired. If you do not know your way around the inside of a television, I never recommend you do so, since, this procedure must be done with the set turned on and you poke your hands around the inside of the set by the high voltage circuit. Hope this helps your decision.
