Hi all, I have a Samsung HL-R5067W HDTV. It will be 2 years old around Halloween. I have used it with no problems whatsoever for the last 22 months. About a month ago I upgraded from a standard HDTV receiver with Dish to the HD-DVR. Shortly after this the TV started randomly shutting off. Sometimes you can turn it right back on, other times you have to try like 5-6 times as it just keeps shutting off. Could this be related to the new receiver? Or is this coincidence? I also though maybe the lamp is going out? I have read the manual for troubleshooting etc, and cant figure it out. Im hoping its not a serious issue. Any help would be great! =)
