I've had my Sony W60b smart tv 48" for four months. It has recently been randomly rebooting itself. Thought at first it was from a faulty satellite signal, but the satellite engineer checked that and can't find a fault. I tried unplugging, no good..then re-tuning but that made no difference. It may be a coincidence, but the software version was recently updated (after auto prompt). Any clues??? Thanks folks.
