6000 - Tosa / Sl-6000 Navigation Button Problems

I went ahead and cleaned the contacts on my Z and my buttons work fine now. For anyone deciding to do some light dismantling due to similar problems I would recommend the following procedure (electrical engineers feel free to chime in on the best method for cleaning metallic contacts):
1. Push the sliding portion of your Z open to expose the keyboard. Look at the back side of the same portion. You will see 2 main electrical contacts each one split into 4 sections by some dividing plastic. Try to scrape away any corrosion you might see and see if this fixes your problem (these are the contacts that are engaged when the slider is closed).
2. If that doesn't work, there are 4 small screws on the SIDE (gray area) of the sliding portion. Removing them will allow you to remove the slider (it is held in place by 2 plastic protrusions on each of the 2 platic sliding arms). You should be able to remove it without much physical deformation -- and no permanent damage
3. When the slider is free, you will have access to another set of contacts to clean (presumably the ones that are engaged when the slider is open?). You will also have access to the contacts on the non-slider portion of your Z. Don't bother trying to remove the back plate from the slider (like I did) as there is nothing to clean...all contacts for the buttons are completely enclosed.
Happy Z'ing.
