My elderly parents tv was switched off at the power yesterday and when it came back on they got this message. The Bravia tv is about 10 years old and they can’t find the model number - their sight isn’t great. We don’t live near and I need help in resolving this issue ASAP. Due to lockdown and their ages no one can go into their home to help. Has anyone an idea? We have switched it on and off again in case it resolved it and it hasn’t. The remote doesn’t seem to move the sections showing either.
