TV loses signal when bedroom light is on

My TV uses the rooftop antenna and gets a great pic till the bedroom light is turned on, then the TV loses the signal. I'm guessing that it is a short and I'll take it to the dealer when I get a chance, but does anyone have any quick ideas to check.
  • My trailer came with LED for most of the lights including the ones causing the issue. The TV is a standard 120V TV, so it wouldn't be on the same circuit as the 12V lights.
    The lights are within a couple of feet of the antenna.
    Definitely could be on the same circuit as the booster which is also in the bedroom.
    It is under warranty, so I'll let the dealer resolve the issue but it will be after our 2 week vacation before I have time to take it in.

    I'm dealing with the same issue in my new trailer. I've come to believe it is RFI from the LEDs and will investigate further.
  • I'd guess it's the LED light. Same happened to us after we installed led's throughout. The 2 closet to the TV, bedroom/bathroom, kill the picture when they're turned on. They're not led light boards, just standard replacement led lights.

    I remember reading somewhere, just don't remember where, that it isn't unusual with some brands of LED's.
  • I am guessing this is a 12 volt TV.
    It could be that the light and the TV is on the same circuit. It could be that the voltage is dropping low enough that the TV doesn't like it.
    It could be that the antenna is on the same circuit and voltage to the booster is dropping that low.
    Take a good voltage reading on the circuit with a voltmeter.

    If you have just recently installed a LED LIGHT BOARD in your bedroom that is probably the cause. Some LED lights that have built-in regulator circuit will emit enough RFI to kill a digital TV signal.

    If this is the case use a $4.99 LED Board from EBAY/CHINA to solve the problem.

    Just a thought for you to investigate
