mobile phone interference

muskymagic

hello,just joined up today, i have recently installed a panasonic 32 lcd tv,and have a great saorview reception, but if some one in the room is using mobile phone , i get green lines and freezing on the screen.My amps and booster are in another room,so i cant see them picking up the mbl phone,has any one else had this problemo?? I have witnessed this happening with some cheapo 'blue diamond' tv's that where on sale around Christmas, but they were freezing due to dect phones being to close, cheers

What type of aerial are you using - indoor or outdoor?

Is it a high end smartphone or a bog standard phone?
Do you have an amplifier for your TV signal?

If the signal is strong enough at the antenna, and if the boosters are the modern type which block mobile phone signals then using a mobile should not be a problem. Does the picture go blocky when for example you watch a DVD from a DVD player? If so it may be the TV itself.

Have you another TV in the house you can try to see if it is the TV or the signal.

Generally if the signal is very strong then the picture will not go blocky. If the signal to the TV is a bit weak, then a nearby mobile could cause problems.

I would say first step is to confirm if it is indeed that make of TV and not something else. It probably is something else, such as a weak signal arriving to the TV.

If you really have problems you can get special channelised boosters and special channel group aerials. These are much less likely to be affected by mobile phones.

Let us know what you try and how you get on.
