What to do if my Technomate TM-5402HD M3 CI Super+ TV Receiver has no picture or sound?
- KKiara OrtegaAug 6, 2025
If your Technomate TV Receiver isn't displaying a picture or producing sound, several factors could be at play. First, verify that the video/audio output is correctly connected to the TV input terminal using RCA or HDMI cables. Also, ensure the satellite antenna cable is properly connected. The antenna's direction is crucial, so make sure it's correctly aligned. A weak or absent signal can also cause this issue; therefore, inspect all cable connections, the LNB, and any other equipment between the LNB and the receiver. Finally, confirm that the channel information settings in the MENU screen are accurate.
