We have replaced our optical block twice, we changed out the lamp twice-first time it exploded inside the tv??? now the tv doesn\'t work for cable but we can use the piss poor cloudy optical block again using hd antenna or thru xbox internet - this tv is GARBAGE end of story! I will NEVER purchase a SONY product ever again - they are basically all the same like our Food industry they just slap some other company name on the final product - we were ripped off bad for this tv paid 3,000 piece of garbage!!!
