Problems connecting my Wii

I had my Wii connected to the main TV downstairs but I have now moved it upstairs and tried to connect it to a TV there but without success. The TV I'm trying to connect to is an Alba LCDW16HDF. I have tried all the different 'source' options but all I get are blue screens. I've re-tuned teh TV on both digital and ananlogue but am at a loss what to try next. Any help would be appreciated.;-)
