RCX 2.0 Firmware downloaded successfully but "Run" does nothing I recently was able to install RIS 2.0 for the first time since I just got a 32bit Windows 7 machine.

I got the IR tower to download the firmware to the RCX 2.0 and it showed exactly the same screens the guide showed, but when I got to the point where I test the motors, I found that the "Run" button does nothing.

I tried installing the firmware 3-4 times and still have the same problem, so I'm assuming the RCX itself has a defective Run button.

Does anyone know what's possibly going on? All the other buttons work, they beep and change the screen when pressed, nothing beeps or happens when Run is pressed.
Could be the button indeed. These buttons are conductive rubber pressing on the circuit boards integrated contacts. Might need some cleaning there... 

Disassembly of the RCX is not easy but can be done. You have to remove the screws in the battery compartment, then pull slightly to disengage and remove the black IR front. Once this is done, you can pull out the PCB and battery case from the top cover. Important note: the PCB is connected to the battery case through metallic blades that can easily bend and no longer make contact. So when you pull the PCB+case, you must pull on the PCB itself, not on the battery case.

Once done, you can clean the button area with alcohol and/or swap buttons to hopefully repair the Run button ("View" button is useful, but not mandatory...).
