The image was fine via RGB Scart but the component cable (in either 480p or 576i/480i) was only giving me a green and purple mix of colours. After fiddling around and with a bit of testing I eliminated my TV as the cause. Removing each of the component connections (and double checking I hadn’t got the red video [pR] and red audio cable [Right Audio] the wrong way) confirmed that they were all sending something.
Either the cable was faulty or somehow my Wii was not sending the right signals. I identified that the blue cable (pB) was at fault. Only green and red signals were transmitting so I only saw green and purple colours – maybe I needed a replacement cable?
Well it turns out I just needed to wiggle the cable near the connection to the Wii! Well I suppose that’s what you get for buying a HK cable from eBay – although if the only downside to a £3 cable is a single installation wiggle then I can live with it.
Hopefully if you have had similar issues with your Wii’s component video this might help.
Other things to check are:
- Swap the Red Video and red audio cables (idiot check!)
- Does it work on a different TV? (maybe an issue with your TV)
- Does RGB Scart give full colour? (this tests the pins on the Wii)
- Do other component sources work? (if not it’s your telly)
- Does a different component video cable work? (the cable is faulty) *only worth it if you have a spare or can borrow another
- If you are using a switch box or similar; does connecting directly to the TV help? (maybe your switch is bust)
I have also read that some cables have a SD/HD switch on them so if you are getting no colour don’t forget to check for that.
