Marking opcode 'standby' as unsupported feature for device 'TV'

[schmeffn]

My TV can switched on with the pulse-eight software, but (currently) not switched off at all.
You have an idea we could proceed also then let me know maybe.

TV: Samsung LE40A559P4F
As descriped from the TV's manuel it should be possible to switch off with Anynet+ (HDMI-CEC).
The feature automatically Switch off (with Anynet+) is set to enabled on the TV.
CEC Version of TV is: 1.3a (as displayed from the Pulse-Eight Software at tab "CEC-Tester"-> Device information)
