first time to hear this, after the storm your HDMI doesn't work anymore, but your old school audio video connector works right? Try plugging the HDMI along with the old school one then, turn off your PS unplug the audio old school SD video cable and see if the TV detects the HDMI.
If you want to see more of Akeno, then you should watch DxD OVA's ( the second in particular) and episode 2 of the specials.
In season 2 (that will air in July), there will be a scene where Akeno sucks Issei's finger and then tries to do a little more than that. And later in the season there will be a topless battle betweem Rias and Akeno over Issei.
