It is completely possible that some types of LED lights may cause interference to television reception. Such interference may consist of a sudden loss of signal or picture quality in a residence where LED lights are in use. Such interference is most likely to occur during evening hours when light globes are most likely to be in use.
Try this simple test before looking at adjusting or replacing your antenna.
- Switch your LED lights off while viewing the affected television channel. If your television signal immediately returns to normal this will provide a very strong indication of whether the LED globe(s) is the source of the interference.
If it appears that the lights are the problem, you may consider returning them to the place of purchase or contact the manufacturer directly.
