It's an interuption in the signal to your digital tuner. effectively the tuner memorises the last signal it got before the interuption and appears to freeze the screen. Ours does it when the heating flicks on. It goes spastic if the wife uses the micro wave in the kitchen, and poor weather effects all the itv channels and channel 5.
Most problems like this are down to a poor signal, check out your receiver instruction manual, somewhere you should be able to access a display which shows signal strength as a moving bar (usually). it should be above 65% at all times for good results, if its marginal = new antenna.
Anyone tell us what happens when someone uses a lawn-mower nearby? My normal tv at home goes funny when my dad mows the lawn. Wonder what happens to digital.
We get a blip and the sound goes really quiet. I thought it was the TV to start with as both a Sky box and a Freeview box did it. Looks like it's a digital problem as when recording, the blips get recorded too.
Utter rubbish this digital TV. It's a shame we're being forced down this road!
we bought a digital antenna, and this wasnt a rip off by the installer cos hes a mate ive known for years, using a special digital antenna works far better than your standard antenna, as has been said many electrical things can interfere with the signal, we have two massive trees in our garden so my mate sited the antenna at the other side of the house with no trees and it worked fine.
