When I try to configure my TV see that error:

However some methods work fine. I try: getSupportedApiInfo, getApplicationList, setPowerStatus, setSceneSetting and few other.

But my target is control PictureMode by setPictureQualitySettings (and getPictureQualitySettings) and that method don`t work.

I try that method at display_control.html and it work.
