Is this a Wii we are talking about? Or something else?
it is a wii
I am unable to get the arrow/hands up on the screen, the sensor bar is above the screen but will not turn off without unplugging the machine
Ok, Let's check the sensor bar.
Do you have a digital camera or mobile phone camera? If so, grab it, turn it on, and then point it at the sensor bar.
If the sensor bar is working, you should see blue flashing from the front of it in the viewfinder of the camera or on the phone.
If you see no blue lights in the camera, the sensor bar is bad.
Try that and let me know.
There is no blue flashing when pointing the camera at the sensor
Ok, then either the sensor is not plugged into the Wii correctly or it has failed.
A new one is not expensive - about $7 CLICK HERE.
Without a working sensor bar, the Wii cannot interpret the controller's signals.
Check that it is plugged in. If it is, get a new one.
