Remote of my TV, KLD-46EX723 has went crazy by itself.

It worked just normally but now it turns TV on or off in every touch.

I can touch any button and it shuts down the TV and touching any other button it goes back on.

I have had TV unplugged a while but it did not work.

Also I have removed batteries from remote but did not help either.

If I use TV on its own buttons on side, it works just fine, Changes channes, volume etc...

Anyone has any idea about problem?
