In addition to taking a look at the wiring harness, if I wasn't risking further damage to the television, I might just err on the side of doing nothing until the issues worsen; I'd have nothing to lose in that--even if they're affected--I don't use SMART features and the existing problems are, at this point, only a "mild nuisance" level.
Another thing I was considering: Factory Re-set in the menu (I think it's called 'Initial Setting'). Would that also re-flash the system's existing firmware?
Again, I appreciate your input.
I've reflashed my 6200 ONCE a few months ago using the USB drive method, and had no issues. I think it's safer than updating it via wireless. Just make SURE the firmware you download is for your exact model version. My tv set is on a UPS though, as IF you had a power outage during the flash, that could brick it, but the flash goes pretty fast. As for a factory reset, NO it will not "reflash" the firmware, but it would zero-out everything back to as if it just came off the assembly line. That MIGHT be good enough and work for you, if you want to try that first.
If that doesn't work, go for the firmware reflash next. If that also doesn't work, (I'd bet it will work though) you've pretty much done all you could by then.
P.S. Mine started doing power cycling also. It turned out to be 2 bad LED's for the backlighting. It's a bitch to tear down the set to the point where you can replace the leds, but I did it, and now all my leds work again, and the tv no longer power cycles at random. I watched a Youtube video on how to do it. Let me warn you though, the SCREEN is so thin, (like paper) it's easy to chip it, and get a permanent line in it. That happened to me, (there was a thin spot, and my fingernail actually just barely chipped a tiny piece!) unfortunately, but it's the very right hand edge, so is still usable. Here's the video I used, as my la6200 had the same led strips as the model shown here:
