Long term Cigarette smoke won't be good for any electronics. When my mother was smoking cigarettes the walls of her home were coated with a thick coating of yellow nicotine. When I sprayed the walls with 409, the walls would drip with nasty yellow drool. This is what would first happen to the TV screen, then eventually the internal electronics would be affected. In Broadcast facilities no smoking is allowed because of the affects.
Will smoking in a small room that my 50" plasma tv is in, do any serious damage?
