i recently ran into an issue with the HDMI ports on my PS50 C7700. All HDMI ports show a 'no signal' message, this started to happen after the power was disconnected. It reckonizes that something is plugged in, but it doesn't show the source. I unplugged the power from the TV and reconnected all devices but that didn't work.
my devices see that the TV is connected, the Anynet connection with my receiver also works, but the image isn't displayed. Any tips?
