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.
Maybe this list can help you, click here
for a list of each widescreen Toshiba TV Service Menu adjustment with details on the purpose of each.
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.
