I have DM 7020HD. I use HDMI CEC command to wake up my TV. But after DM update my TV starts on a wrong input, now it uses TV input instead of AV. Did not change any settings on TV or Box, just did update ... and everying is broken now. Is it possible to fix?

Dreambox 7020HD. After startup box goes to standby, but sends hdmi signal to wakeup TV! Is it possible to fix it? Do not send hdmi CEC command if box goes to standby after reboot.
