I've recently fixed an LCD TV to the centre of the party wall in my terraced house. About 1.5m along the same wall is a standard lamp. The old dear next door is complaining that when either of these are on it causes interference to her radio. It turns out that her radio is positioned directly between the lamp and TV on the other side of the wall. Neither the lamp or TV are earthed, the LCD TV coming with a two point mains into the back of the unit. I've tried running an earthing cable from the back of these units to a nearby heating pipe but this does not seem to have worked .. Any ideas?

Sheet of tin foil (preferably earthed) behind the LCD TV??
Have you experimented to figure out which one is the source of interference? I could understand if it was TV, but you said either? Its hard to see the lamp on it's own causing a problem - unless there is a very bad contact.
Could be that the lamp lead is acting and an aerial for any mains bourne interference from the TV - try unplugging the lamp.
Also do you have an aerial booster, and have you moved your aerial leads as a result of the new TV? We have a booster to feed the rest of the house from the combined freeview/video/DVD/RF signal. The resulting co-ax feeds leak a bit - a result you can tune a portable telly into the current freeview channel in most rooms and the garage - magic!

which radio band VHF or LW/MW?
'if LW /MW it is probaby radiating via the cables, and ferrite rings omn the leads are an easy wayt to reduce this dramatically.
If VHF it is probaby radiated. Wave a prtable radio over your equi[ment to see if you can identify the source of emmission.
The RSGB have an EMC website, which while aimed at ham radio transmitter problems the same physics applies equally in this sort of case.
