I have an Insignia installed on the wall connected to a Hardon Kardon receiver. I did all of the install myself. I have video cables running up one side of the wall into the attic and back down behind the plasma. I have a horizontal line that scrolls slowly up the picture, but only when i have my kitchen light on. Obviously this is the problem, but what can I do to correct it?
if the kitchen light is flourecent then change it. there are many new models on the market, low energy circuits etc. or just put in regular light fittings. you're getting a hum bar from something emitting a high frequency....
