How can I fix my Luxor TV?

Every time I turn on my TV it says that I need to carry out 1st time installation. I go ahead and scan all channels, but will not show any info on EPG about any channel. Then once I have turned it off and back on again, low and behold.. 1st time installation. Can anyone tell me what the problem is and how to fix it? Luxor TV 40" which is JUST out of its years warranty
