Question about Emerson EWF2703 27" TV
Most of the time it is just a coil or the high voltage transformer itself that is vibrating causing the noise. The high voltage trasformer has an iron core that goes through the center of it and there is usually a giant clip to hol it together. That clip ometimes is loose causing the vibration. Usually you can listen for the sound when the back is off (careful there is 30,000 volts present while in operation and the tube holds a charge even when off) and press on different coils near the transfomer with a long plastic tool (no metal to avoid shorting components out). When you find the one that is the most sensitive with the slightest touch you can usually apply hot glue or silicone over it (with TV off and unplugged) and let it sit for a while. Good luck and be safe.
