I've got a new plasma tv on order (my Loewe CRT tv blew after just 3 years!). I want to wall mount it and there is only one wall where I can hang it. However, underneath the intended location for the screen, there is a power socket, which will come in useful to power the tv, but obviously the ring cables run down the wall (i.e. within the wall) and will pass behind where the screen will eventually be hung. Apart from the obvious, like detecting and marking the cables to avoid with the mounting screws, is there a possibility that the electric field generated by the power cables might cause interference on the screen, or is the technology not affected in such a way? Any thoughts would be much appreciated. Thanks.
