My beko tv has a system setting on BG. I need to change it to L but it won't change. How do I change the system setting?

Hi
you need to get into the service mode to change such features..sometimes user Remote restricts to get in and it needs special service RC unit .Try the following methods..here it is:
HOW TO GET SERVICE MODE. Procedure:
1. Press Service In/Out button on the Service RC or activate the Picture Menu with the user RC and enter 8500 or 1903
2. Red, Green, Yellow and Blue TXT buttons are for Feature Setup, Geometry, White Balance and AFC menus respectively.
3. Press 0 button to exit the Service Mode ----
another 2 user recommended methods HOW TO GET SERVICE MODE:

a.....TV off...press: "pr+" and " pr- " on remote and while pressing both turn on the TV

b. if your RC model is #909 ,press " color - " than service mode will come...
