How hard is it to change the motherboard on the bose sounddock

SOURCE: No sound from Bose SoundDock

I had this problem on my SoundDock. My iPod would charge on the dock just fine and when I played my iPod on the dock, it would look like it was playing, but have no sound. Since my Bose was out of warranty, this is what I did to fix it. #1 Unplug the adapter. #2 Unscrew the four large screws on the bottom of the speaker and the three small screws under the dock. #3 You'll see one long ribbon connection and one very short one. Check to see if the ribbon connector coming from the front of the speaker system came loose from the green board. You'll only be able to see 1/2 an inch of it sticking out, and it's not easy to plug it back in, but it's possible. Just take your time. #4 Carefully put everything back together being very careful not to let the ribbon fall out of the plug again. #5 Make sure to plug in the DC adapter the correct way. There's a very subtle difference, but there is a difference. There are four prongs - two are square and two have slightly rounded corners. If it's not plugged in the correct way, the dock will have a static clicking sound. On my adapter, the words "DC power" are on the top of the plug.

You probably have a broken docking connector or bad power supply. Contact www.invebo.com to get a replacement board. It takes minutes to fit. They also sell the USB charge upgrade to enable you dock to charge the IPHONE on the Soundock original. Try the PSUif you can. The click is the PSU shorted that can be caused by a fault n the sound processor. Invebo will repair it for you too.
