|---|---|---|
| No power indicator light | Power adapter not connected or faulty; power outlet not working. | Check power adapter connection to amplifier and wall outlet. Test the outlet with another device. |
| No signal or poor signal on TV | Loose cable connections; antenna issue; TV not scanned for channels; amplifier malfunction. | Ensure all coaxial cables are securely connected. Check your antenna for proper positioning and function. Perform a channel scan on your TV. If issues persist, contact support. |
| Picture pixelation or freezing | Signal too strong (over-amplification); interference; poor quality cables. | While rare with this model, try bypassing the amplifier to see if the signal improves.
