HI-FI

> Recently, a friend accessed the service menu of the above television,
> and irritatingly, entered various numbers into the TT-- field.
> In doing this, he appears to have changed the sound system from I to
> DK and has caused the onscreen menus to become garbled. Also, the
> defult background colour for blank channels is now purple.
> Undoubtedly, there are probably many more as-of-yet undiscovered
> problems.
>
> So, is there a way to reset this television to its factory defult (for
> the UK)?
>
> Any help would be very appreciated.
