It just makes it so much harder to unscrew the bar. So I decided to take the sensor bar apart to see what I can do to fix it. I have to use 7.5V to power it up which matches some other posts I read.Īlthough it works with 7.5V (or even 9V) P/S, it is still not ideal as it is not a common power source. Maybe it works for some newer sensor bars. I tried with a variable voltage power supply and I found out it isn't quite true. I read from post on the web that says I can power the sensor bar using 5V USB. The other problem is simply that the sensor bar needs to be hooked up to the Wii and it makes it difficult to get the sensor bar connected away from Wii. I have two problems, the IR LED is no longer emitting (a working sensor bar should lights when viewed through camera) and I don't know whether it is the Wii or the sensor bar that is broken. The sensor is in the Wiimote and the sensor bar is really just emitting infrared signal. It is common knowledge that sensor bar has no 'sensor' at all. The Wii is not getting a lot of use lately and I noticed the sensor bar isn't working. The same old Wii that I bought back in 2006.
