You have messed up the tuner configuration. The factory reset has options to reset tuner settings, you can experiment with it. Aternatively, flash your image again, do not restore settings after it reboots. Download/Save the page with the tuner config advice just in case you have internet access issues.

Please transfer the file called "settings" located in /etc/enigma2 to your PC. Zip and upload it here. I am sure it has errors.
