I have a strange problem with my LX59 with HDMI.
For example i'm using nvidia, when i switch to Sat cable sometimes i have no audio or video, when came back to nvidia again is the same. I have to switch to other source that is not in use and switch back again to one for sources above. Other strange thing, when i put the TV (Pioneer Lx5090) on standby and leave the av and nvidia on, when turn on the plasma the screen is black with no video nor audio. I have to power off lx59 to get it work again.
What i'm missing?
