ES6900 settings

[evesham]

hi all, great forum you have here, i recently went into the service mode menu to try and change my Locale from France to UK. I couldn't get out of the service menu by pressing exit, or return etc, the only way I could was by putting into standby. Since then none of my settings are saved and every time I switch the Tv back on its in dynamic mode.
can anyone help.
thanks
