We had a power cut a few nights ago and since then we have not been able to access any channels including SKY which the TV was set up for. The television is in the bedroom so not so important but very annoying. Have tried, as suggested, to reset time and date, but this has made no difference. The only thing I can access is the SMART page but this does not provide any tv programmes. I have tried re programming but it displays that there are no channels available. Any help would be greatly appreciated before I have to call in a TV engineer!
