We've had this tv for about a week.IWe have it wall mounted in a bedroom on the second floor of our house. This morning, with no one touching the remote, the menu for the input pops up on screen. It then started scrolling through the options and finally started selecting them (DVD, AV, etc). I switched the input back to TV and it did it again. This went on for about 15 minutes and then resolved itself. Is the TV on some sort of frequency that someone outside could be triggering? Another solution? Or should we be calling Ghost Hunters? hahaha. Seriously, though- what gives?

Re: Menu Appears "on it's own"
I have seen five types of causes for this type of fault. The fifth one is extremely unusual.
The uPC, and or the IR reciever and remote data amp circuits in the set went defective and started addressing functions from noise generation.
The control panel circuit board in the set has gone defective, and randomly addresses functions. (Sometimes people spill liquid inside while cleaning the set and damage this circuit board).
In the room, there are some compact fluorescent, or fluorescent lighting, and the frequencies from the lights are causing the IR addressing to malfunction.
The remote control itself is defective and sending commands. (Remove the batteries to test).
You have an unscrupulous neighbor that enjoys to annoy you, they can see your TV set in the window, and he or she is messing with it using a compatible remote! Very very rare to have this one! (Keep your curtains pulled to see if this fixes this type of fault).

Is the power led on? Is the panel back light on? Tap gently on the screen. if you see whitish on the screen when you do this the panel is on. Press menu button does the menu appear?
if the set is 5 yrs old or older many times capacitors on the power board go bad. They are recognizable by a slight domeing on the top instead of being flat. these are replaceable at component level.
you can check on ebay under the model number for a board. The board is held on with screws and plug in connectors.
You would have to use a mounting bracket specifically designed for the type of installation you describe and it certainly would have to be fastened into the studs behind the sheetrock. A TV of that size will be heavy to lift and install in the bracket
If you search on Ebay for your TV's exact model number, sometimes you can find a replacement stand for it there from someone who has their TV mounted to the wall and is no longer using it. These are normally fairly heavy and bulky items, so Ebay purchase prices and shipping costs can vary widely.
I did not see any for your exact model of TV available there when I looked, but the online selection changes daily, so you can always keep checking back. Just search on Ebay for 'HITACHI TV STAND' or 'HITACHI TV BASE' and you will see a wide variety of them available for different Hitachi TV models as well as what the average price for them is.Otherwise you can just buy a generic wall mount floor stand for around $100 which bolts to the TV like a wall mount, but actually sits on the floor instead of being bolted to the wall.
Here are some links to a few different models currently available on Ebay which include pictures so you can see what I mean:
Acquiring wall mounts for television are according to preferences. For example, wall mounts that provide the TV dynamic directions to suit operators requirements would have separe requirements. The multidirectional wall mount provides the TV capability to swirl around several angles. Howeever, acquiring wall mounts as requirement to encamp the TV also placement on safe areas from which the device is observable is an alternative considerations.

Me again. I removed the rear plastic housing of my TV a few weeks ago on a hunch that the resonance frequency of the two speakers were matching that of the plastic rear housing. Yep. Once I removed the plastic housing (about 8 screws), all speaker vibrations ceased. It's been fine ever since. However, I don't particularly care to have the back off of it, although I see no high voltage parts like a yoke, etc. sticking out or within reach. It's also not mounted to a wall and is in a position where folks can't easily get there hands into the back. I'd still write to the CEO of Samsung since this is a wider problem that they should address without charging a tech fee.
Place the tv on its screen flat on a soft surface,
you need to remove all the screws, not just the stand one marked.
Lift the back panel and then you will be able to slide down the stand, when you have removed the back cover you will also see where how your wall mount will fit to the chassis.
Place all the screws back on the back lid.
