- These symptoms are typically caused by electrical interference from domestic appliances, switches and computers in your home or a nearby neighbour. The most common cause is a faulty boiler or central heating thermostat, which can lead to regular bursts of interference, for example for 10 seconds every 20 minutes
- Sometimes, high-voltage electrical equipment outside your home can cause interference
- If you have a baby monitor, cordless phone or another wireless device susceptible of causing some wave interference, make sure it isn't too close to the TV
- If you have equipment such as a video or DVD/BD player or recorder and the aerial lead is plugged into it, first disconnect the device from the TV and then plug the aerial lead directly into the TV. This will show whether the equipment is causing the interference. If you have several units connected, reconnect each one until you find out which one is causing the problem. If it turns out that one of your connected devices is indeed causing this issue, please contact its manufacturer for support
