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.
1. S-Video output is not working
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:
Quizard was a series of quiz games published by TAB-Austria in the ’90s. What makes it special is the fact that it is one of the very few arcade games based on Philips CD-i hardware. The protection of Quizard 1.x and 2.x has been figured out quite a while ago and since then it is emulated in MAME. Quizard 3.x and 4.x, however, refused to run – until now. A first step was done when Team Europe dumped a protection MCU a couple of years ago. Very soon, they will release an MCU board that will turn almost every CD-i player into a Quizard arcade machine. I received a sample last week and just finished assembling and testing it.
While doing my research for another project (finding a plug for the Philips CDI350 RGB in/out port), I came across an old IBM MIDI/Game port adapter. It is listed with P/N 29H9467 (FRU P/N 29H9269) and can be used with some models of the ThinkPad 760 series (760CD, 760ED, 760XD, and also 765D). What makes it so special is the plug. It is similar to the 26-pin external floppy connectors used by several laptop brands in the ’90s. While most of the external floppy drives used a 17 mm wide plug, this one is 20 mm wide. This JAE datasheet lists the plug as TX20A series connector, part number TX20A-26PH1-D2P1-D1.
Last year I began to disassemble and repair one of my Philips CDI350 players. This has been covered in the article Philips CDI350 Repair Part 1.
After that, it took me a while to make a list of all capacitors, to find replacement parts (the original Philips part numbers are not useful anymore) and to find shops that had them on stock.
The scanned CDI350 service manual on ICDIA is missing the pages 78 and 79, which contain the parts lists of the servo and power sections. I found some of the missing parts in the CDI360 service manual and some by comparing the removed parts with both service manuals.
Two portable Philips CD-i players (CDI350) came into my care last month. They show common errors, such as not loading any CDs and not storing any settings, and also flickering screens. Let’s have a look inside and repair them.
The screen becomes normal after a while so that I can navigate.
