Introduction

I ended up breaking a part, but it does not seem to be needed…

Should be similar for the R700 & R800, but I don’t have one…

What you need

Step 1

              Remove the unnecessary parts
  • Remove the USB-Receiver.
  • Open the battery compartment.
  • Remove the batteries.

Remove the USB-Receiver.

Open the battery compartment.

Remove the batteries.

Step 2

              Remove the sticker
  • To remove the sticker that’s covering the next screws, I used a small slot screwdriver and carefully inserted it at the shown position. There is a little notch here that guides you in.

Step 3

              Remove 2 screws

Below the sticker we have two Philips screws (red). Unscrew them.

Now carefully pry apart the two halves of the cover, starting from the side of the battery compartment.

Step 4

              Just another screw.
  • The green board is where all the application logic is in, so don’t scratch it.
  • There is one single screw. Unscrew it.
  • Carefully take out the green board. The connectors for the batteries are attached here, don’t break them (though they are quite sturdy). Step 6 has an image how the board looks from the other side.

Step 5

              Finished
  • This should be the end product.

Step 6

              Not actually part of the disassembly...
  • The reason why I disassembled my presenter was, that the laser diode (red) did not project out of the case any more. You can clearly see the laser being at a very odd angle. I can not imagine how that happened.
  • The yellow marker shows the battery connectors you are not supposed to break in step 4.
  • In the last image you see the “fixed” laser diode. I just gently pushed it down, now it’s working again.

To reassemble your device, follow these instructions in reverse order.

R800 disassembly is indeed similar, although the sticker is in two parts. The battery image should also be removed.

Seems that Logitech has produced several generations or versions and calls them call R400. Mine looks all different inside, for example the laser diode cannot bend any longer, it has got its own bolting-down-plate and two flex cables to connect it. My PID is WD502XM. Mine was purchased in Denmark or Sweden some time in 2014 or 2015. My laser stopped working too (while the rest of the functionality is still working). How can we set up different versions on ifixit, so that we will not confuse versions and discussions/instructions? I am new here, joined today.
