Logic LCXW30NN6 (Apex NLC27C1) scart input and service help needed

[ProDave]

I have a Logic LCXW30NN6 which as far as I can tell is a re badged version of an Apex NLC27C1

A few questions.

The set works fine apart from the scart input neither auto selects nor does auto aspect ratio switching work via scart.

Is this normal and a limitation on this set, or do I have a fault or need to change some settings?

Does anyone have a service manual?

How do you access the engineering or service menu's on this set?

Thanks.
