I found that using a "backlight" or bias lighting behind my RPTV greatly improved my Dish viewing experience. You can get a commercial version called IDEAL-LUME from http://www.cinemaquestinc.com/ideal_lume.htm
but I made my own, following their specs for 1/3 of the price.
A 18" Verilux Fluorescent Bulb, 6200K w/95 CI and a 18" corded fluorescent fixture for $19 total from Menards. Works great. I have it velcroed on the back of my Hitachi 57S700 RPTV. I did have to do some placement adjustments to get it just right. I leave it on all the time, 18W.. bulb should last 1.5 years. I always had a glare problem before I tried this using ambient lighting. Couldn't watch in complete darkness for long due to the eye strain. I highly recommend trying one if you haven't already.
