Bigtime shot in the dark: Do a rescan with rf disconnected. See if settings, like manual clock stick. I'm guessing one of your channels is giving your unit problems. Trick will be finding which one.
I have used my 515H on clear QAM and never had an issue. My cable feed strips the PSIP and doesn't add SCTE-127, so it's pretty clean. I still get 22 analog and 120 digital channels. I never use the analog.

If your setup has ANYTHING that could contribute to actually turning power off, like an external, switched power strip or wall switch, that can cause reappearance of the Setup menu. If no switch, check the UPS for possible "off" condition in some weird (?) circumstances (prob. nothing here but you never know).
Here's a help file on CC, describing the 2-step process to turn DTV CC ON for viewing and separately for RECORDING... not all programs have CC, and they can take up to 1-minute to start appearing:http://www.avsforum.com/avs-vb/showpost.php?p=12298458
If a program has ANALOG CC, that can only be seen by turning the TV's
CC control on (usually CC1 for English), and it HAS TO BE recorded since it appears in the VBI of an interlaced pic, but the TV controls viewing.
Many cablecos charge more for digital tier channels but send analog anyway, and you might not notice unless you have a machine that can report the true signal data as analog or digital (Tivo, for one). I don't think turning DTV CC on will work in that case.
Thanks JoeKustra and Wajo, for your help. You nailed it, Joe, with your suggestion that a channel was causing my problem. I don't speak the technical language well enough to describe the situation in technical terms, but here's what I found.
My cable company is what I would call weird. They broadcast the same TV programs on different numbered channels. For example, I can watch the local ABC channel on Channel 3, Channel 3.1 or Channel 1.103 (and maybe others). I normally watch it on Channel 1.103, and therein was the problem. With the 537 on channel 1.103, closed captioning does not work, and if I shut it down while it is tuned to 1.103, the settings all go back to default when I turn the 537 on again. Conversely, if I operate on Channel 3 or 3.1, closed captioning works, and the 537 holds its settings when I turn it off and back on.
I don't know how long it would have taken me to discover that without your help.....matter of fact I probably would not have discovered it and would have returned a perfectly good unit before the return period expired as I always watch the 1.xxx channels.
So THANKS a bunch!
