My 50H82 just arrived Thursday. It's terrific, but a few times the picture went away for a brief moment, then faded back in, as if you'd turned the set off and back on. It even displayed the channel info. I don't know if this is normal, like a periodic self-reset, or if this is a problem. I will mention it to the tech who comes next week. (The onboard speakers went out an hour after setup, but I half-expected a sound bug after hearing of others' hissing speakers.) I've got the 4 year in-home service contract, so no worries, just curious.
