I would appreciate any assistance in diagnosing a problem with my Samsung DLP DLP HLR5067WAX/XAA. I've uploaded a video of the problem to youtube. (since I'm new to this site, I can't post a URL, but you can see it if you search my youtube ID: bluedog925).
As you can see in the video, when I plug in the unit, the TV starts automatically, but the picture is highly distorted and jittery, though audio seems ok. After about 15 seconds the picture freezes and audio goes out, then the picture goes out also. After another 5+ seconds, the distorted picture and audio come back. This cycle repeats. The TV will not respond to pressing power button. I unplug the unit to turn it off. I tried pressing other commands on the remote (eg, MENU), but no response. Would a bad DMD chip cause this erratic system behavior?
I was going to order a replacement DMD board (part BP96-01102A on samsungparts.com), which doesn't come with a new DMD chip. I saw on another forum that a poster said his problem was fixed when the repairman replaced his digital control board assembly, which I think is ASSY PCB P-DIGITAL (part ASSY PCB P-DIGITAL). Both of these are over $400 each on samsungparts website so I'd like to be reasonably sure what I need to replace before I start ordering parts.
Thanks in advance!
