KD-55XF9005 - Wii will not connect

[JL2020]

Our Wii has worked fine on all our previous TVs, including a Samsung curved model and a Sharp LC50LE751K

The picture and sound on our new Sony is blurred/buzzing. 

The red/white/yellow connector from the Wii uses a 3 into 1 adaptor into the yellow AV socket on the Sony - this is how it connected to the Samsung (now gone) and the Sharp, which we still have and still connects fine to the Wii.

Any help is most welcome please!

The connections may be different between different tvs. Check it out with a meter if you have one or get in touch with a service centre

Hi @JL2020 @rooobb 

When all else fails, read the manual 🙂

The fat, multi-country, and largely useless Reference Guide you got with the TV contains the diagram at the bottom of this post (just item 2; ignore the item 3 snippet at the bottom) which shows you the requirement for the cable that goes into the relevant socket on the Sony TV; it’s a 3.5mm four-pole adaptor, which you should compare with the adaptor you have now. If that is not 3.5mm, or not four-pole, you need a new adaptor cable for the Sony.

It doesn’t need to be made by Sony, but it does need pole 3 to be ground, so check this, if you can.

As does your existing adaptor, even if it is 3.5mm four-pole. We might hope these are standard pin outs, but they might not be.

A continuity tester, or multimeter, can be useful here if you have one; there should not be a circuit between pole 3 and any of the input sockets on the adaptor. But if you haven’t got one, you can use the process of elimination below.

As long as pole 3 is ground, you can try the other pins one by one. Start with the yellow-ended cable from the Wii, and try it in each input on the adaptor until you get a picture. After which, get the white-ended cable from the Wii and plug that into whichever remaining input makes the sound come out on the left. And plug the red-ended cable into the remaining one, and make sure sound now comes out on the right as well.

If one of these inputs doesn’t give a signal, then it’s going to pole 3, and the adaptor, even if 3.5mm 4-pole, isn’t suitable, and you will need the Sony one or an exact equivalent.

If it does give all 3 signals, though, then we might hope that each cable winds up plugged into the same-coloured input on the adaptor; but if not, it doesn’t matter, except you will have to make a note of what goes where.

Please let us know how you get on!
