When I turn on TV a logo displaying LED TV logo and a number of other logos display on upper left side of TV. It goes awat after a few seconds and then comes back. It continues to repeat this and I can't seem to get rid of the logo.
Apparently it's on demo-mode so you have to go to 1. Set up 2. Plug and play 3. Then change to home instead of demo

You are likely to have a module bad....part number BN94-00864A and if you take it out (unpluggs) you should inspect it for capacitors that may be domed or pooched up at the top. If so they should be replaced first before getting the module as the capacitors are about $1.00 each. Do a search for Samsung parts online if you need the module and call them toll free

I have the same problem of the set turning off and on by itself. There is a circuit in Samsung TVs that would shut it down if a very loud noise occurs in the program being watched, but I have not noticed that correlation. My problem is solved by vacuuming the back panels of the set. They do not seem to have any significant dust on them, but I think the vacuum sucks somewhat inside of the TV and does some good with the fan that is supposed to be cooling the bulb and the mirror. It seems to work for months on end and when the problem recurrs, I vacuum again.

could be just a few bad capacitors on the power supply, if you want you can do a visual of the power board caps will appear swollen on top and are easy to solder in cost about $1 each
value is 1000mf at 16volts usually replace four of them

If you take the back off you might find a couple of bulged electrolytic caps on the power supply board that need change, or just buy a new power supply at www.partstore.com

I managed to resolve this issue. TV was apparently set to store demo mode which can be turned off under the Tools menu.
It worked for me thanks
