Question about Symphonic ST420FF 20" TV
The television is making a loud buzzing noise when it is on. The noise doesn't always occur; but when it does occur it is loud and disturbing and ruins the enjoyment of watching the television. The noise is not localized to a specific channel, and there is no way to predict when it will begin or end. I have had the television for about three years and I think that the television is in someway defective.
This can happen with the flyback transformer's brightness which can be adjusted , also the power transformer can make humming or buzzing sounds which can't be adjusted , also this can happen with the picture tube or the CRT board failing , and sometimes chips with heat sinks or the IC's themselfs
