I have the Samsung DLP TV HL-S5687W and a couple months ago the TV just started to turn off randomly. Then it became more frequent. So I read online and found that the lamp is the most common problem so i replaced it. But the next day after replacing it the problem began to occur again. I talked to the Samsung tech support and they said it might be the color wheel so Ive ordered that and will be coming in tomorrow. As anyone else had this problem where theyve fixed it with a known solution where they dont have to spend more money then they have to.
