Have I bought the Lidls Sat system and have hit a snag in that I don't have a scart socket. In a previous thread Brambles suggested to use a RF modulator so I took myself round to Maplins and found one , unfortunately its mains powered and I wanted to get away from using my invertor too much. So has anybody any ideas on how to hook this system up without a scart socket without using 240 volt:?:
