Why is the light in the room off?
Changed the wallpaper in the room. And accordingly, the electrical box pulled from the wall. I set it back, but there is no light. Looked the wire was disconnected. Reconnected and still no light. There is light in the living room, but not in the room. What to do?
Hello! It is not clear what kind of wire and in general the whole situation is not very clear. Most likely not something was connected, there are more than one pair of wires in the junction box, so they could mix something up. Call an electrician, he will ring the wiring and restore the necessary connections.
