I have two, a 50 inch DLP I picked up as a closeout and my monitor is a TV/monitor combo. Both are Samsung and have gorgeous pictures.
From almost day one the 50 in. had a problem with turning off. I thought it might be the nature of the beast and initially this was an easily solved issue by hitting the "on" button.
Over time this became a possible heat issue so I added external fans to cool it. As of yesterday they rarely help at all. I'm going to try to open & clean what I can in hopes of a cure.
I frequent thrift stores and see almost brand new LG TV's more than I should.
