This is an overview of the lists of capacitors and other components that I had to create in order to repair or modify my devices. Currently, all of them are already featured in my repair articles, but I will add further lists that are not featured yet or are a work in progress.
Recently, I acquired yet another CD-i player for repair and it came with a Philips 22ER9021 CD-i Gamepad. The gamepad showed two common signs of usage: Broken cable insulation and an unresponsive D-Pad.
The coating is broken right behind the cable strain relief. I’ve seen much worse cases of broken insulation and even ripped out conductors, but this still needs to be fixed before it becomes worse.
For quite some time, I was puzzled why my CDI660 was stuck in a reset loop after I inserted the test/dummy plug into Input 1. I expected it to boot into the Service Shell, like most other CD-i players. My solution so far was to use a 490 system ROM in the 660 whenever I needed the Service Shell (the compatibility and also the error were discovered during this experiment). However, this wasn’t a very practical approach because I had to open up the player and dig out the system ROM from underneath the DVC every time.
When CD-i Emulator with -testplug option showed the same behaviour, CD-i Fan figured out what is causing this error: The Service Shell module sv is missing from the 660/670 system ROM.
In this article, I will show you a simple ROM patch to enable the Service Shell for the CDI660.
The second generation professional and authoring CD-i players of the Philips CDI60x series feature a DE-9 RGB port. To improve the video quality of my CDI605T/20 and also to prepare for future experiments, I built a prototype RGB SCART adapter. The needed pinout is documented in the 605 and 605T user manuals on ICDIA.
After the first tests were successful, I made this schematic for an adapter with a SCART socket (output) for both RGB video and audio:
Continue reading Philips CDI605 RGB SCART AdapterIt has been on my table for a while to figure out a working Philips CDI490 RGB SCART modification. The topic caught my interest when it came up in the community on The world of CD-i last year. Back then, I thought it would be quite easy because the small 470 and 490 CD-i players share a certain mainboard (Mono IV) with their big brothers 660/00, 220/80 and 210/60. There are only some components missing that could be figured out by looking at the service manuals.
However, I couldn’t try it out back then because I didn’t have a working 470 or 490. I focused on repairing my 470 first and then adding a PAL/NTSC switch. Eventually, I bought the needed components and two broken 490s to experiment with.

It’s been a while since I opened my first Philips CDI350 portable CD-i player and published a repair guide with capacitor list. I have already received some positive feedback that this was helpful for others fixing their players. However, part 2 of the article ended with a big question mark because some topics remained unsolved. Let’s have a look at the status of these topics and see if I can resolve them today in Philips CDI350 Repair Part 3.
This turned out to be my fault. After carefully following the traces to and from the video encoder and comparing every component with the service manual, I noticed that I had soldered two electrolytic capacitors with the wrong polarity: C938 and C991. I can only assume that this happened because I used the + marks as indicators and not the white dots. Just look at the vast amount of plusses:

The other option, CD-i Link, and how to connect a Philips CD-i player to a modern Windows PC is covered in the first part. Make sure to follow the guide to set up the connection and the terminal program Tera Term.
CD-interlink (alternate spelling: CD-i’nterlink, CD-Interlink and CD-InterLink) is a program developed by Novaré International (and human interaction inc.) in 1994. It is dubbed The Complete CD-i File Manager and has some useful functions to view and manipulate single/multiple files in the NVRAM. Some functions require the connection to a terminal. At first sight, it seems to be easier to use for beginners because it has a graphical user interface that can be operated with a CD-i controller. Don’t get fooled by this though, because file transfers are actually more complicated to set up than with cdilink.

The other option CD-interlink is covered in this article.
Back then, I built a null-modem cable which I still use today. Over the years I’ve used it to connect all my CD-i players to PCs and portable devices for data transfer and debugging purposes. However, some models required additional adapters and/or different connectors.
For most Philips CD-i players you will need to make a null-modem cable with Mini-DIN-8 and DE-9F connectors according to the CD-i Nullmodem Cable Specification found on this page. The Mini-DIN-8 connector goes into the back port of the player (usually labelled INPUT 2, RS-232 or SERIAL I/O).
Continue reading Back Up and Restore NVRAM Data With CD-i LinkThis is an attempt to collect all known and available modifications for Philips CD-i players in a single article. Consider it a work in progress – I will add new information from time to time. Please give feedback if you find an error or want to add something to this article.
Due to the plethora of different models, versions and revisions of CD-i players that have been sold under the Philips / Magnavox or entirely different brands (OEM), it is virtually impossible to create one big list that contains every player. I chose a different approach with several lists to cover most of the hardware combinations: Available modifications, mainboards, and video encoders.
