Thank you for coming so quickly.What seems to be the problem?All the channels suddenly stopped working.Did you make sure all the cables are plugged in?Yes, I checked and double checked them.There may be some kind of signal interference.Is there any way you can test that?Of course! Give me a moment, please.Do you know what the problem is?Not quite yet. So you can't change the channels?No, not at all.Well, you'll be able to once you change the remote batteries.
