Service Menu Access Procedure To access the service menu, press and hold the handset sound mute button whilst pressing the TV's front panel 'Menu' button (under the front panel cover on the TV). The up/down channel buttons on the handset step through the options and the left/right buttons change the data values. Turn the TV off to get out of service mode and DO NOT touch any other handset buttons whilst in service mode. Service menu access is also similar for many other Toshiba large-screen TV's so this procedure may work on other Toshiba TV's - even those sold outside the UK.

The factory settings of each service menu option will be entirely different on every TV manufactured, due to component, tube and scan coil tolerances, so don't under any circumstances adjust your TV's settings to my factory default settings or your TV's picture will probably look awful! The factory settings are provided out of interest - the useful part of this document is actually the definition of each service menu option. You will see that some geometry settings are duplicated for each screen mode such as 'Cinema' and 'Subtitle'. This could, for example, help resolve a geometry problem that's present just in one screen mode.

I hope help you with this.

It sounds like your TV is in Shop Mode.
Shop mode is a set of picture parameters that have been optimized for a store showroom or display floor. Shop mode does not allow you save any picture settings such as brightness or contrast.
To get the TV out of Shop Mode press and hold the Menu button on the front panel for three seconds, the picture will blank momentarily then reappear with “Dynamic Mode” shown on the screen. At this point the picture parameters can be changed and saved.
