I have a analog TV that is still working fine and no plans to replace it. Over time, it has developed an audio hum - I'm guessing it's 60 Hz. When the picture is dark, the hum is nearly gone. The brighter the picture, the louder it is. I'm guessing some kind of filter on the speaker connections would do it, maybe something as simple as connecting a capacitor circuit.... But, as I ain't the sharpest feller with audio electronics, I thought I better ask the genius pool here!

First I thought was a power cord was near the antenna cable, but that doesn't seem to be the problem.

The key word in all this is "cheap". Anything over $10 is way out of line.

- Are you sure it's coming from the speaker? Deflection yokes are known to hum as the mastic snot that locates the convergence shunts dry up from age.

Yes, the hum goes up and down with the volume.
