OKm I opened the beast and here is what I found. Here is the link for more detail pictures : https://retro-visual.jimdofree.com/autr ... sid=986596I should maybe change the 2 bigs capacitor + the greens with gold around ? I have some knowledge about soldering but not any about electronics... I imagine that the big ones can be dangerous to manipulate (I unplugged the player 2 weeks ago, but...) Should I take some precaution ? What sort ? Here is the link for more detail pictures : https://retro-visual.jimdofree.com/autr ... sid=986596

I dunno if it's a good idea to mess with those screws unless you have an oscilloscope and service remote (or Harmony or other remote programmed with its codes). If you do, you should follow the service manual, but I don't see the service manual for the CLD-959 in https://manuals.lddb.com/LD_Players/Pioneer/CLD/ . Take a look around and see if you can find one that's close to the specs/internals of the 959, it should be good enough. A test disc might come in handy but I haven't really needed one whenever I needed to adjust the centering/tangential screws on my player, I just adjusted them until the signal was at its highest point on the oscilloscope. But you might need a CRT TV or monitor, the service mode signal can get pretty screwy and a video processor might not lock onto it.

OK, I got back to the player. Opened it again, searching for a bad cap or other causing the video distortion. I found that the player was modded for AC3 output. The mod was installed at the place of the second video output. For that, the modder cutted the video signal on the board and connected the wires for the audio mod. I realised that the solder was very bad, and may caused the video distortion, as the solder may touch both audio and video signals on the board. Here is the picture of the solder : I don't know exactly what to do now, but I think I will insold the mod from the video out at first. The wire is connected to this little box. Don't really know if this is the AC3 board or if this part is in any CLD-959?

For that, the modder cutted the video signal on the board and connected the wires for the audio mod. I always hated seeing people mod their players in that way. In a way, it's easier to take over a jack you don't feel one needs, but it's really a hack that at best really ruins the original functionality of the player. And I know some people think punching out a new hole may also look like ruining the original look of the player, but if it's done neatly I feel it adds to the look of the player and will still retain all of the player's original output jacks as is. mimylovesjapan wrote: I realised that the solder was very bad, and may caused the video distortion, as the solder may touch both audio and video signals on the board.
I don't know exactly what to do now, but I think I will insold the mod from the video out at first. It might not be causing any issues. If the trace was completely cut off, there would be no way for the AC3 signal to make it back to the video chip. However, it wouldn't hurt to remove the mod and clean up all the possible solder bridges and then re-test the player. If the issues is still happening, then there is more to search for and possibly the issue is still dried caps. mimylovesjapan wrote: The wire is connected to this little box.

That box is definitely not a part of the CLD-97 based on schematics of the player (I would look inside my 97 but I'm too lazy to open it up @ the moment). It sounds like the person who modded the player thought it would be a good idea to put the AC3-RF board inside a shielded container. Honestly speaking, considering it's located all the way @ the front the player, I would think the excess wire run alone would defeat the effectiveness of such a box. I would open up the box to peak inside and see if it's really an AC3 board and then remove it along w/ the wires. You can re-install the board @ a better location (and without the box) once you get the issues resolved.
