Hi, I have recently purchased a Toshiba 42WT29B rear projection tv and I have noticed coloured tints down the left and right hand side of the tv. There is a blue tint on the left 1/4 of the tv and a red tint on the right 1/4 of the tv. I have played about with the convergence but I can't imagine this is the problem as you would expect detail to have rgb problems, not large areas. Has anyone had this before, or does anyone know what this is and if i can do anything about it short of sending it back? Thanks.
