Your VHO ballast is acting like a little radio transmitter. This may or may
not be simple to cure. You must attack the problem at the source, i.e., at
the ballast. The best approach would be to replace the 2-wire cord with a
3-wire grounded cord, and attach the green wire to the metal case of the
ballast. Filtration involves picking up a pair of 0.001 to 0.005 mfd, 600v
Disc Ceramic Capacitors (once commonly available, but not so much these days
of low voltage circuitry), and wiring one from each side of the 115 VAC
terminals to ground, inside the case. An alternate (and less effective)
approach would be to pick up a couple of ferrite loops (Radio Shack probably
carries them), and wrapping 3 to 5 turns of the 115 VAC lead through and
through these loops. They also sell RF filtered outlet strips for computer
applications, but the last time I was at Office Max looking for one, they
didn't have any. You might be able to order one. Look specifically for the
words "RF Filtered." Moving the TV and ballast to different rooms can help.
You might also try a "High Pass Filter" in line with the antenna leads going
into the TV. Again, Radio Shack should sell these, but with the advent of
cable TV, there is less and less demand for them. There are more aggressive
ways to eliminate this interference, but without having a background in
electronics, you probably would not want to attempt them. If all of these
methods fail, you might want to contact the ballast manufacturer and see if
they sell retrofit kits to modify the ballast to eliminate RF (Radio
Frequency) emissions, or if they offer to do this service for you by
returning the ballast to them. Sometimes manufacturers are aware of their
defective design (and it IS a defect in the design of the ballast!), but
don't put the fix in every unit made because it would drive up their cost of
manufacture, and they figure few people would even know what's causing the
interference, or may not even encounter the problem. Hence, they will supply
you with the parts to effect the fix, or fix it for you, but only if you
complain.
