I am putting a new 25" TV on a corner shelf in my basement and something behind one of the walls is causing a big blue spot in the lower right hand side of the screen. I cannot move the shelf or the TV from where it is so I need to find another way of fixing this. Would a large metal plate keep whatever is causing the interference from hitting the TV? What if I grounded the metal plate?? Thanks for your help! ------------------ Check out my home-built mame cabinet here!
