Just got home from a few days away and when I put the tv on the stb was showing the language wizard set up page and all my channels had gone. When I tried to reboot it returned to the same page also saying ;timer file corrupt: I have tried to load the statellites and channels and I have even had a picture but then for no reason it goes green screen and goes back to langauge set up wizadr and I have to do it all again. Any ideas. Thanks
