TV: MG7.1E Customer service mode

Revision history
Include alternative method for entering customer service mode
First appearance

Note: Most of this information also applies to other chassis' (eg. MG3.1E / MG3.2E / EM3E)

The customer service mode (CSM) shows the current settings of the TV. It is a 'read-only' menu; no changes can be made to the settings.

Entering customer service mode
Press the [MENU] button (TV) and the [MUTE] button (remote) simultaneously until the menu appears (takes about 4 seconds).
Alternative method: first press the TV-[MENU] for 4 seconds and then press REMOTE-[MUTE] until the menu appears.
Depending on the software you can also enter the Customer Service menu by pressing 1 2 3 6 5 4  using the standard remote control (thanks to Vsevolod Ilyin). Version 02581 does not seem to support this method.
