Our new TV has static-like cracks when we turn on a light switch or the dishwasher, etc. It also makes the cracking sound when we get up from the sofa like we are making static. Usually only the sound and not the picture are affected. Will this shorten the life of my TV? Is there anything I can do to stop it?
Yes get a humidifyer for the room or call an electrician. Sounds like an old house without a good or faulty grounding system. yes it can certainlt shorten the life of anything electrical in the home. Static electricity is bad for electronic circuits.
