Electrical problem with TV when T5's are on?

[sr07g6]

Anyone have any knowledge with electrical?? I have a large rear projection TV that is in the same room that my 120G tank is in. It is on a separate circuit with a GFI outlet. When my T5 lights come on the TV becomes very fuzzy and static"¦ This only happens when the T5 lamps are on for some reason and any other time it is completely fine??? I don't understand as they are on completely different breakers and it seems that this is all that's being effected in the house...Any ideas?

Where is the ballast in relation to the TV's power cord?

T5 Ballast is on the back of the canopy and is about 8 to 10 feet away. The ballast is also less than 4 months old and is the Tek Sunlight Supply 48" retro.

Put the TV on a power strip with a surge protector. Some ballasts can be "noisy". The surge protector may filter it out.

Are both the TV and the ballasts grounded? They should be.

run a ground line from the ballast casing to some copper plumbing. make sure your copper plumbing is grounded wherever the water comes in.

Rear projections are more susceptible to electrical noise of all kinds than LCD/Plasma/LED TV's. You're either dealing with line noise, EMF (electro magnetic field) noise, or both. As Nico says, sometimes the fuses and breakers in a power strip can filter out minimal line noise. Grounding the case of the units can also filter out some EMF. A better way to filter out EMF though is to wrap the ballasts in some kind of steel. The cheapest/easiest way to do that is to cover them with an old metal coffee can, or a metal paint/stain can.

If the EMF filtering doesn't work, you can try buying surge protectors with line filters built-in, but remember, you get what you pay for

I dealt with this on my icecap halide ballasts.

See the thread on how I got rid of it here: http://www.forum.digitalaquatics.com/viewtopic.php?f=4&t=8119

I had it with a MH ballast but the noise was being picked up on the coax between my tivo and tv, if I used the composite connection it went away. Luckily it ended when we moved.

I had noise issues messing with my AC JR (cant remember what anymore) so I bought some chokes at da shack and it filtered the noise out.
