Mini,

If you do have a multimeter, use the Ohms part to check if all wires of the cable you are using are not broken at some point. I am not talking about being broken on one of the connectors, I am talking about inside the cable.

Check also the battery voltage.

Thank you all for your help.

like i said, sunday i'm going to test an S-Video cable and a flat tv, and a crt tv. I also need to have a multimeter to test continuity in the rgb cable.

I come back to you very quickly!

I love this little community ❤️

With a little delay, here is the latest news. in fact everything works, the problem I had had to come from my setup!
Test 1 - S-video = everything works (the image is gray because I had not changed the switch from NTSC to PAL)

Test 2 - RGB = everything works equally!

The test images are strange, but who is this woman ?!

I always have a low-light display, I will have to find a way to remedy this, if you have any ideas don't hesitate !!

Mini

Hey Mini!

I am happy to see your CD-i working!
Is the low light issue due to the Frequency of your TV? 50Hz or higher?

sorry i misspoke. I wanted to say that the front panel display of the module is weak. I posted a photo showing that the lighting was very dim. I wonder if it comes from the display itself or elsewhere!

Good to hear that everything works!

You might want to consider buying are better converter from SCART to HDMI. I recommend an OSSC - it won't have any problems with the signal. The only downside: It can only deal with all kinds of RGB signals; no composite or s-video.

Regarding the VFD, I've searched a bit the www:
They tend to fade over time (just look at the age of the machine).

Thank you again for your help !
I will have to study your links, in order to know more and I hope to find a solution!

Otherwise concerning the OSSC, I wait to see the price and the improvements of the pro version before choosing which one to take 🙂
