    A friend of mine recently had ceiling fluorescent lights installed in a room in his basement. He says that they cause interference on his TV in his living above them, both with the satellite box and watching DVDs. Any suggestions what he can do for this?

    Thanks,

    Jack

    Depending on the type of ballast the lights use, electronic ones, probably what he has, do generate RF noise.

    I really wouldn't want to watch TV with overhead lighting no matter what they are. You can go to a retail store and get that. Turn the light off, use a small table lamp or some indirect lighting (even compact fluorescent) to do the job.

    I believe Jack means his friend watches his display in the living room while the flourescent light in the basement causes the interference from down below. I'd recommend simply turing off the flourescent light when the TV is in use.

    You can install EMI/RMI filters as necessary to eliminate the noise that the lights put out.

    Sorry if I understood...........use a AM portable radio. Tune to a empty area or a weak station. You won't miss hearing the 'buzz'!

    I would still use a different fixture with a different ballast since that is waht is causing the problem. Just like computers, fluorescent fixtures are very noisy (thanks to the FCC not putting a tighter limit on the RF they generate!).

    If Home Depot doesn't have the RFI filters they should sell a better quality ballast that has internal RFI filters. Don't skimp on price if you want to eliminate noise.

    You can also check with a local electrical supply like Graybar. They should carry what you need.

    Another option would be to buy a Power Conditioner for the TV. A good one will eliminate any noise coming in on the the power lines (which is what flourescent lights do). It will also provide extra lightning (surge) protection for your tv.

    Where can I find a Power Conditioner for my TV's and are they expensive and where do I install them?

    Wanted to say 'Thanks' for a specific solution.

    That helps. Need to know more but can contact Graybar and get options and pros and cons.

    Appreciate your input as I just installed 2 Home Depot T-8 fixtures and lamps in garage and now the livingroom TV is barely watchable when lights are on. The existing T-12 fixtures never caused this problem.

    New isn't always better, I guess.

    I definitely agree. I had the same issue before with my lights and the filter works.
