What to do if my Sony SDM-N50 Marketing says 'NO INPUT SIGNAL'?
- RRyan AdamsJul 31, 2025
If your Sony Monitor displays 'NO INPUT SIGNAL', it means either no signal is being input, or no signal is being input from the currently selected connector. Check that the video signal cable is properly connected and all plugs are firmly seated in their sockets. Also, verify that the input select setting is correct and that the video input connector’s pins are not bent or pushed in.
