samsung dlp 50" hdtv (bought in 2006) goes blank by itself after a couple of hours of viewing satellite. satellite receiver is connected to tv with hdmi cable (same thing happens with component cables). not sure if it happens with dvd player, don't watch long enough or it just doesn't happen with dvd? lamp is new (old lamp did same thing), screen goes dark, audio still on, lamp still on, no picture. to get it to work again i have to turn the tv off and turn it back on again. it comes back on quickly. this can happen several times over a few hours of watching the tv. have dusted with compressed air inside the tv. colour wheel is only 14 months old. any ideas?
