LN-T4066F Turning On/Off or Unsupported Mode automatically

I own the above device for a few month now and I noticed now and then that the device is turning itself off and back on after a few seconds. I can reproduce the problem hence there is little chance the that tech support will find anything. Sometime it takes a few months until it come back sometimes more than once a week there is really no pattern. Also, sometimes the screen turns black during playback of Blueray or DVD with an error message 'unsupported mode'. Turning the TV of and On always fixes the problem. Since both is happening only from time to time it's just annoying rather than a serious problem but perhaps someone has an idea how to fix this? Obviously the problem is known to Samsung but the only recommendation thy have is make sure the timer is turned off which in my case has been turned off since delivery.
