What to do if my Insignia NS-48D420NA16 TV has no power?
- RRoy ButlerAug 22, 2025
If your Insignia TV has no power, first ensure that the power cord is properly plugged into a working outlet. If it is, try unplugging the power cord, waiting 60 seconds, and then plugging it back in and turning on the TV. Other devices (for example, a surround sound receiver, external speakers, fans, or hair dryers) may be interfering with your TV. Try turning off one device at a time to determine which device is causing interference. After you have determined which device is causing interference, move it further from the TV to eliminate the interference.
