You have problems with your power up circuits. It is more than likely a fuse blown in some part of the TV that is keeping it from coming on. Also almost everything from a Computer to a $10.00 Calculator starts up by running a self diagnostics test on it's circuitry and if it detects any problems it will shut down or will go into a standby mode. Your TV has detected a problem some where in the circuitry and went into 'safe' or 'standby mode'. As I said in the beginning it could be a fuse, then again it could be about anything. I'm saying fuse because the heating and cooling of the element in the fuse often leads to metal fatigue and causes them to open up. Check the back and see if it has a 'user friendly' fuse panel and go from there. Look for a 30 amp blade fuse [it will be green] and see if its blown. I think that model has a history of blowing that particular fuse. If not, and you are not experienced in TV Repair don't attempt to take the back off and fix it your self, because there's places in there that will fix you good. You will need to take to a reputable TV Repair shop. I hope it's the fuse and that this helped! dhgill1949
