The LE3990FHD TV may show no signal after plugging in the antenna due to several possible reasons:

1. Antenna Issues – The antenna may not be properly installed or connected. Ensure it is securely plugged in and positioned correctly.
2. Signal Reception Problems – The antenna may not be receiving a strong enough signal. Try adjusting its position or using a signal booster.
3. Interference – Nearby high-voltage power lines or communication cables could be causing interference. Install the antenna away from such sources.
4. TV Settings – The TV may not be set to the correct input or tuning mode. Check the settings and perform an auto-tune or channel scan.
5. Hardware Fault – There may be an issue with the TV’s tuner or antenna port. Test with another antenna or check for visible damage.

If the problem persists, contact TEAC Customer Support at 1300 553 315 for further assistance.
