I have a Sony Bravia TV and I have a problem switching it on. I will switch off at night using the remote control but the TV will not switch back on again the next day unless I unplug from the mains and plug it straight back in again. I can then switch it back on using the remote. It is the same using the remote or the on/off button on the TV. It doesn't do this all the time it will sometimes switch back on using the remote without unplugging but will start as if it has been switched off completely and not restarting from standby.
