So After using my Razor (The Philips Norelco 9000 model) I noticed that the on/off activator switch was not working. At first I thought it was broken but then, I came on here to this Website Ifixit.com and found some answers not everything but some Ideas. I was annoyed. I then decided to open it up realizing after reading @Jstanman’s comment about moisture that the moisture that got into the machine messes with the conductivity (those are his words). Here’s the plan:
Step 1: Open up your Philips Norelco 9,000 Preferably with a set of small 2.4 mm Flathead screwdrivers or just any old flathead screwdriver you can wedge in there. I managed to free it up a bit then just pry it open with my nails.
Step 2: Once you’ve got your Philips Norelco 9,000 open you’re going to want to grab a rag of some sort i used what is known as a microfiber cloth and dry off the inside! This is where you get to see the inside and I noticed just how flawless the inside is it’s fascinating and quite simplistic in design.
Step 3: Then just pop back on the backing and the on/off cover and your Philips Norelco should work!
I hope this helps! :-) Peace & Love,
Santino
