My tv says maintenance mode?

@rl147 if anything else fails try a factory reset. This will clear all your presets and any favourites you have set

1: Make sure your TV is on standby (i.e. off, but plugged into the wall)

2: Using your remote, press the following buttons in exactly this order: INFO – MENU – MUTE – POWER.

Note: You have to press them rather quickly one after another, and make sure the remote is properly pointing to the TV.

3: The TV will now switch on, and after a moment, display the service menu. If after about 10 or 15 seconds the service menu doesn’t appear, switch off the TV and try again.

4: Press the Options button (It’s the first option).

5: Press the Factory Reset Button (Again, it’s the first option).

6: The TV will now switch off.

7: Switch the TV back on, and begin the full setup process from the beginning. From here. Let us know what you get.
