Do you want a better video output on your CD-i 450 or 470/490 player? And you have some experience in soldering some extra parts on the maiboard? It is now possible to buy a RGB Do It Yourself kit to upgrade your player with RGB out. In the package you will receive a circuit board and the right components, wires and of course the RGB port. If you're interested, head over to our community The price is 40$.
RGB out on a CD-i 4xx player was a new request from a customer, to get RGB output working on his Philips CD-i 450 console. The Philips CD-i exists in a variety of set-top box and console versions, some with vastly different components and part arrangements. Some are easy to mod, others harder, some not possible at all. The 450 console was in the “not possible” to mod category until AssemblerGames forum member Taijigamer2 found the CDi 220 service manual through another forum contact of his. Manual can be found here: http://freeservicemanuals.info/en/servicemanuals/download/Philips/cdi210.pdf
With this part of the schematic it was discovered that the video encoders could be switched from s-video Y/C to RGB by pin 14. With pin 14 is lifted while connected to 5v (through a 1k ohm resistor) RGB mode is enabled. This applies to both BT9106 and BT9107 video encoders and they have the same pin-out. These encoders can be found in different CD-i units. The RGB signal can be taken from pins 4,8,6. Sync can be taken from either pin 2 of the BT9106 or from the composite video socket. The CDi 450 is fairly easy to dismantle and gave me no surprises. Once the RF shield was removed the motherboard can easily be accessed and removed. These RGB kits can be easily installed, but of course you need some soldering skills as the contact points are quite small.
