Hi, my Samsung HLN467wx DLP has been running great (other than the color wheel replacement a couple years ago) but now has developed a bad problem:
Turn on the TV, and all appears normal for a couple of minutes. Then flickering lines and color / artifacts begin to cover the screen. The entire picture appears completely corrupted/glitched within 30 seconds or so. The sound continues normally. No lights on the front panel are flashing or lit. No odd sounds come from the TV. At this point the power button on the remote and TV are unresponsive (the sound cuts off, but the picture corruption continues). In 10 minutes or so the picture goes completely black. After pulling the plug and letting the TV sit off for a few minutes, I can restart the TV and it looks normal, until the problem begins again in a minute or two.
If I unplug and restart the TV immediately after the above problem, then I get this new problem:
the TV seems to start normally, with sound coming on, but soon it shuts down and restarts itself before ever displaying any image. It does this 3 times, finally resting on a black screen with all 3 front panel/circle lights (Timer, Lamp and Temp) flashing on and off (Timer and Lamp are green, and Temp is red).
I've been searching around the net for hours today, and only seen one other mention on another forum of what appears to be the same problem, but they got no response. Any ideas?
I did read of known problems with the Digital and DMD boards, and that in some cases Samsung may even cover replacing the parts even for out-of-warranty TVs. Would be great if this is possible, is there any info available?
