I found few explanations about NTSC/PAL switch for CD-i 200/00, CD-i 220/20, CD-i 210/40, nevertheless there's nothing about CD-i 210/60 and the mono IV motherboard.

I haven't tried it with a Mono IV board yet. A quick check of the service manual tells me that there is a pair of resistors that connect CPU pin 58 to either +5V or GND in map section C2. Try moving 3290 to 3203 for 60 Hz.

Hello,
Thanks for you advice !
I will try this as soon as I'll receive the switch and wires I ordered yesterday.
If it works I will take some pictures of the switch mount.

Cool, please take some pics for our Open-source section.
Thanks

Don't forget to buy a regular 10 kΩ resistor. Soldering wires to a SMD resistor isn't going to be easy...

@rosewood, just to be sure (for my own knowledge), is it a SMD resistor or a SMD inductor?

Most of the jumpers are resistors, at least on the Mono boards.
Mini MMC = regular solder bridge to switch between 50/60 Hz
Mono I and II = 1 kΩ
Mono III and IV = 10 kΩ
But as I said before, I haven't tried it with a Mono IV yet.

Thanks for the clarification.

Ok, it works. Just tried it with my CDI660/00.
You'll have to remove DVC, CD assembly and the mainboard. The resistor pads are on the back of the mainboard. In the first picture I've marked the four pads (resistor 3290 has already been removed). The two lower pads go to CPU pin 58. Connect them with a 10 kΩ resistor to the center of the switch. The upper left pad is for 50 Hz and the upper right pad for 60 Hz.

Yes, I've also added a new topic in the hardware repair section.

I've just finished to install the switch and it works.
Many thanks to Rosewood for detailed explanations.
It was quite simple with taking time to do things step by step.

I am really happy to hear this!
Thank you for letting us know your work!
Rosewood is the man 😎

Good work!
You can check out this page to see what else can be done with your CD-i player:
https://retrostuff.org/2020/01/12/modifications-for-philips-cd-i-players/#Mono-IV
If you share a screenshot/the terminal output of the low-level test menu, I can tell you if a 32 KB NVRAM modification is possible or not. Look here for instructions: https://retrostuff.org/2020/04/03/back-up-and-restore-nvram-data-with-cd-i-link/

@datapro, do you still have this player and could post a picture of the system ROM?
