Hello everyone.
I have a CD-i that will not play audio. I can play games, watch CD-i movies, and (seemingly) play audio cds but I get nothing from the sound. Neither from the the RCA Jacks, SCART Output, nor the headphone jack. I did a recap hoping it would help but has still not solved my problem. My Timekeeper is fine and the cs4328-ks chip has proper voltage. I have no idea what to check next as it's almost certainly something in the audio circuitry. I did a Service Shell test and the CD Player works fine. I can get into the APU/KEY menu but have no idea what I'm doing in there so I've tried changing attenuation values to no effect. I will note that my front panel does not work, neither the buttons nor the display (on occasion it will flash strangely but is normally blank). My controller port works fine and don't think this would effect audio circuitry but figured I'd mention it just in case.
My next step is to start swapping chips out but would like to perform a low-level test first. Does anyone here have any ideas as to what I could look at or if I could bypass the audio circuitry entirely with a different amp? Any help would be appreciated.
Thanks

It’s a 220/39 unit which I believe is a Mono I board, will provide photos of the board later as I’m at work now

Here are some photos, sorry it took so long got delayed with holiday stuff. Included are photos of the full board, the audio section, the reverse of the audio section, and the servo/ cdic sections. I have checked all points in the audio section for continuity and reflowed some areas after doing a recap. Any ideas on what to do or where to look next would be appreciated.

Hi happy to have these photo.
First , here it look to have tow condensor faulty look like inflate , in green there is to coil look to be damaged and possibily shortcut.
In the second there is some wire soldered and look to bypass audio from the scart connector , it look to be realy badly soldered and cause shortcut to the ground .
I think is this cause your no sound issues .

Thanks, I'll see if I can find some online to replace them.

Hello and welcome to The World of CD-i vip77!
1st of all, have you measured the capacitors? Do they still have the correct capacity?
The bottom ones doesn't seams to be dead, I do believe it is the light of the flash that makes this white color on the top of them.
You do not heard nothing at all? Not a noice?

Hello, I replaced the capacitors, I'm going to order some new chips and replace those to see if it will help. No noise at all, no cracking or popping, just silence. but the video works fine.

Hey @vip77 happy to see you again.
Do you have a multimeter with a capacitors reading? It is better to check them 1st and verify if they still have the capacity indicated on them.
@rosewood, do tou have a 220/39 service manual? Can you provide the Low Level Test for the audio c check?

I've sent him here to seek for help because I don't have time to look at my CDI220/20/39 at the moment. The service manuals for /20 and /39 are the same and available here: http://www.icdia.co.uk/svcmanuals/index.html

Hello, I came across a service manual at http://www.icdia.co.uk/svcmanuals/index.html so I've been looking through it. I've got the parts I need to put together a RS-232 cable in order to run a low-level test but I will probably not have time to do it until after the holidays. I will report back the results once I've done the test.

Exactly.
I am under a cable project. I am waiting for your results. Good luck.

Hello everyone.I appreciate all who tried to assist me in this matter but I have fixed this issue. Turns out the main problem was that I am an idiot. Seems as though my Voltage Step Up/Step Down converter was not functioning properly and therefore was not providing quite enough voltage for the unit to work entirely properly. Luckily it was under warranty and the item has been exchanged for a working model. Now my CD-I works fine and with proper audio. Sorry if I wasted anyone's time on this matter as I found it immensely frustrating but I am happy you were all willing to help. Thanks!
