"Hello, I am an owner of a Toshiba 40H80 rear projection television. About 2
months ago I had some convergence problems. I attempted fixing it myself.
Unfortunately I altered the geometry and had to have a professional repair
the mess. While in the service menu. I believe I did something to the
sound/volume. I have no sound form the TV but I am able to use my home
theatre(separate from the TV). I also have a Playstation 2 and cannot get
sound to produce using it.
