Oxford Transmitter. TV will not pick up all available digital channels, specifically ITV, Channel 4, Film 4. Also, majortiy of non BBC channels break up. All BBC channels good and pick up BBC Oxford. Tested aerial on another TV (not Sony) and picks up all channels from that aerial and no channels break up. Have tried to complete factory reset, but not an option in settings. Tried tutorial from Sony, but at the stage where you press the TV power button, TV turns off and stays off. Tested Remote (ED009 supplied with TV) following tutorial from Sony and all works. So not remote, not aerial, must be TV, but TV used to work fine, all available channels. Anyone able to help?
