What to do if my SmartLabs SML-5112W Set-top boxes screen displays 'No signal'?
- JJoseph OliverAug 2, 2025
If your SmartLabs Set-top box displays a 'No signal' message, it could be due to several reasons. First, ensure that the STB is properly connected to the mains supply. If it is, check whether the STB is turned on using its remote control. Also, verify that your TV is set to the correct input source that is connected to the STB.
