Sound problems with LG TV

[robbo7]

Hi, recently bought an LG 42LG7000 television with freeview, problem i have is that the radio channels when tuned in suddenly go silent after about 1 minute, it is only the radio channels that this happens with.. thought originally it might be the signal with the aerial, but tv upstairs [samsung] which also has freeview has no problems.

Anyone

Are just receiving your signal via freeview, do you have cable tv/radio at all that you can test it with?
