I thought I had a dead battery pack, because the unit screen showed the "charging" battery animation.
Unfortunately, a new battery pack did not fix the problem... it is a dead charging unit.

I now noticed the blue lights do not illuminate anymore when I dock my TSU3000.

The philips website does not carry the charger any longer (the charger part #)

EDIT: My docking station had a blown fuse ($1 - $5 part). I will post a pictorial on replacement soon. If the blue lights don't illuminate on your dock when the unit is in the cradle, you probably have a blown fuse on the inside. Easy fix if you can handle a soldering iron!
