AV1 remains in the upper left corner of the screen. Volume diagram remains in the center of the bottom of the screen. Both of these are on the screen all of the time.


Hi,

This sounds like Screen-Burn which is very uncommon for an LCD TV.

You could try resetting the TV.

- Press and hold the 'Exit' button for 10-15 seconds.
- Follow on screen prompts to reset and retune.

Failing this it *Could* be screen burn.
