a while ago I got a french lot which included a Philips 210 CD-i. the seller said that the touchpad that came with it doesnt work but I found out that the touchpad works fine its the controller port which doesn't work. so I opened it up to have a look at it
I think I found the problem looks like its a missing wire. can someone please check their player to confirm that the mini din plug is meant to have 9 wires coming from it? if that is the problem then it shouldnt be that difficult to fix
controller port repair help

The missing pin is number 6 which according to the documentation in http://www.icdia.co.uk/docs/pointing_devices.zip is "reserved" and hence not necessary.
For a working pointing device only four wires are needed:
pin 2 - RXD (data from device to player)
pin 5 - GND (signal and power supply ground)
pin 7 - RTS (reset pulse from player to device)
pin 8 - +5V (power supply for device)
So your missing wire almost surely isn't the problem; it may be that the electonics inside the player are broken. Have you tried the other pointing device port (there is one on the front and one on the back).

The front port is connected via the so-called "slave" processor and supports only pointing devices (these are all input-only); the back port is connected to the main processor and supports bidirectional i/o and hence more devices (is is essentially a "normal" serial port and can be used as such by CD-i software).
Players supporting a splitter combine the two ports in a single connector and usually have a third port supporting only pointing devices.
CD-i software is supposed to support pointing devices on all ports (this was a publishing requirement by Philips Media) but it wouldn't surprise me if some software out there doesn't do this correctly.
If it doesn't work on either port I would assume that the device is bad, not the ports. The only way to know this for sure is to test with another device or player...
