Your in the wrong forum, this is for projector screens. You should post in the flat screen forum matching the model of your TV. To answer your question I assume that is an edge lit LCD TV and that is why we don't like them in general in these forums. Some models are worse than others but Full array back lighting is preferred over edge lit.
