Hello I have a Samsung DLP HLR5067WX/XAA that when you turn it on the picture is great and everything is fine, but after a few minutes the video goes off and the sound stays on. I checked the back of the tv and the bulb stays lit when the video is out and I have also pulled the rear cover off to make sure the fans are working and there wasnt an abundance of dust (fans are working and cleaned the little dust that was in there). I was leaning toward a temperature issue so I left the cover off and bypassed the switch but this did not help. If you turn the tv off and then immediatly turn it back on the picture comes back like nothing was ever wrong but after a few minutes the video goes out again. I am hoping someone can help me with this problem. Thank you in advance!!!!
