Ok so I remembered that there was a topic related to an E0 error ( [CLD-D925] E0 error [SOLVED!]) and it was the same problem, the switch position at the back was also wrong, now that I moved it back, it works ! But I declared victory a little too quickly, there are still two issues to solve. The first one is the weirdest, i've got the same issue that I had on the s315, there are lines appearing when the disc reaches the half of it's playtime (25-30 min, a video here https://youtu.be/k-ieSLcSkp0) The second problem I have is that the laser can't reach it's b side position, it gets stuck somehow (video here : https://youtu.be/JIOyoeJ7-qc) And for those two I have no idea what to do.

When replacing the pickup all the calibrations will be off, so you will need to go through the service manual and follow the steps set out for when you replace the pickup. https://manuals.lddb.com/LD_Players/Pio ... l_Scan.pdf covers the NTSC version of the 515/915. And simoni just updated this alignment guide for the LD-4300D/4400 - it's for a more complex player but a really good description: edit after cplusplus's comment below: https://www.domesday86.com/?page_id=2896edit: The above's for more general issues. Make sure the motor holder is in good shape on the new pickup - the 315 has the dreaded VNL16xx version - and maybe remount the pickup and make sure there isn't anything blocking it? krbahr or a more experienced tech will be more helpful than I ![Smile :)](./images/smilies/icon_e_smile.gif)

As happycube said, when you swap a laser pickup, a full alignment procedure must be performed on the player. The pickup you placed in the 925 was aligned for that specific S315 when it left the factory. Even if you had a a pickup from another 925, you would still need to perform an alignment. If you are not experienced with using an oscilliscope, etc, I would strongly recommend finding someone who is very experienced in electronics repair and give them GGV1069 and the service manual. Also I believe happycube meant to link https://www.domesday86.com/?page_id=2896 (Thanks for pointing this out! Simon's guide was the only one I knew of for alignment and now it is even better!)

I reopened my player today to try and and "eye" calibrate the thing using the "video level" screw and I think I sort of succeeded, the video is brighter (it was way too dark before), and a little less noisy but still not as clear as I think it should be, though the picture is pretty correct so i'm not gonna touch that again. As I opened it I also looked for anything that might be blocking the laser's path to side B, the only thing note worthy I found was that the rail doesn't seem aligned correctly (picture here https://www.noelshack.com/2019-37-7-156 ... 154417.jpg), I tried to move it but it won't budge, I don't want to force anything so I wondered if maybe it was the correct way, if someone could check on his 925, I would really apreciate it. Anyway I think I'm on the right path to succeed in making my player fully operational, It'll be so awesome when I'm done.

I always thought that swapping a laser pick (as well as head drum on a VCR) only require a minor tweek of some electrical adjustment but mechanically speaking nothing should need tweaking. Still need to do all the adjustments. I was just focusing on the laser not flipping and seeming to get stuck from going back at a certain point. If you press side B to close and start the player if should flip over to side B and then the adjustments come into play after it starts to spin and read the disc.
