That sounds strange. Make sure you don't have something funny going on with your remote like your cat is sitting on it or the batteries are dying in it. Use the buttons on the TV to turn on/off and look in your manual to see if there is a factory reset which is available.
Failing that, it may be a power supply issue. I would take check to see if it is under manufacturer warranty and call their support centre ASAP.
