Hi Lucky
I'm afraid you are out of luck this time, unless you provide the make and model of your TV to give us half a chance of answering your question.
There are two solutions that I can suggest in the meantime, the first is to go to ebay and buy a replacement remote control and the other, which I am certain will stop your tv being in standby mode and this is to unplug the tv from the power socket.
