Philips 21PT5420 CRT TV - Can't access SOUND menu item

[Marwell]

Hello,

I would like to ask you for advice.
When I press <MENU> key on RC the full menu (as is shown in the user instructions manual) is not displayed. Only reduced MENU is shown.

The MENU should look like this:



This MENU is not present in my TV (my MENU is pseudo-animated and consist from single line).

The only available options are:

BRIGHTNESS
COLOUR
CONTRAST
SHARPNESS
AUTO STORE
MANUAL STORE

The worst thing around is the fact that since it is not accessible SOUND menu I can not set these parameters (bass, treble values) so the device has deplorable sound quality (when you select MUSIC option using SMART AUDIO bass and treble lacks - the sound is even worse and unusable with other selection of SMART AUDIO).

Any advice?

Thanks a lot.
