Poor audio from Freeview box? Thomson DTI6300-16

[foxhole]

Have a tv set up in lounge and feed from Thompson freeview box [with recording facility] to my kitchen tv so can watch freeview etc in kitchen.
Feed to tv in lounge and kitchen comes from freeview box via a amplified aerial splitter.Used to have the same set up with a video providing the final feed and that was fine but new set up gives an audible continuous tone on kitchen tv which is about 60% of the tv 's volume so anoying unless I have tv at low volume. Lounge tv seems unaffected.

TV tuning of the kitchen set, perhaps?

I think you may need to elaborate on exactly how you have this rigged up, is it the composite video out you are using from the Thompson?

Give us all the details!

"Feed to tv in lounge and kitchen comes from freeview box via a amplified aerial splitter" so no composite feed.
Tv is tuned correctly and works fine on all other channels.[moved channel output on freeview box to 42 so as not to conflict with other channels]

Is it possible to borrow a different freeview box to try?

Had a sony freeview box previously, no problem.
