Most TVs have a power button located on the front of the TV that you can push to turn it on. If your TV doesn't have one, you could buy a universal remote and use that or buy a new tv.

The fact that it turns on is good. Most likely the trouble is with a data line internal in the set. It may be the remote receiver IC or a push button on the set. A stuck button or switch can confuse or load communication between internal microprocessor circuits. Take a look or feel each of the push buttons do they feel the same when pushed ? Do they have a slight snap when pushed. The tac switches used in most cases are made like a small old clicker. If one feels soft and has no snap it's probably your trouble. If so tap lightly around but not on the button and it might free itself. You should just have Samsung replace whatever is the cause.
