About a week ago, I noticed that my Sony KDP-51WS655 had lost its digital channels. So, I reran the auto program and it found them again. A couple of days ago, I turned the TV back on and again noticed it had lost its digital channels. Since we were watching a DVD, I didn't bother to reprogram it right then. Yesterday when I got home from work, I turned it on and reran the auto program. I confirmed that it found all the digital channels and shut it off. Later last night, I turned it on so we could watch a DVD and decided to check the digital channels. Once again they were gone! I noticed that the analog channels were still there but the TY wouldn't cycle through them using the CH + or - buttons. It would only access the analog channels if I directly punched them in by number. It appears that every time I shut the TV off, it purges its channel progamming. BTW, I am running basic cable directly to the TV so there is no cable box involved. I used to get all the networks in HD plus a bunch of random digital channels. My relatively-new LG 37LG50 LCD TV in the other room is fine and hasn't lost its channels so I don't think this is an issue with the incoming signal. Any thoughts?

Thanks in advance!

OK, last night I tried unplugging cable TV and my OTA antenna to the unit and reran the auto program as I heard this will "clear" the programming. After I did that I hooked everything up and reran the auto program. Once again, it found all the channels - both analog and digital. I then shut the TV off, turned it back on and "BOOM" all the channels were gone as before. Is the tuner in the TV shot?

Try unplugging the set.

Thanks for the idea Bill! Not sure why I didn't think of it myself?!? :confused: Anyway, I unplugged the TV for a couple of hours and I also tried a full reset (as described in the manual) and neither worked. I still lose all my channels when I turn the TV off - the digital ones are completely gone and the analog ones are there, but only by directly punching the numbers in. I still get some HD via OTA. I'm beginning to think the QAM tuner is shot. :mad: I think I'll unplug it for the night and try again tomorrow night...
