- This one's a little bit different insofar as it's part two of the Philips Laserdisc player repair and we get it going and working well in this video.
The laser assembly I bought was purchased from Aliexpress:
www.aliexpress.com/item/33039...
I totally missed to say what laser assembly is used in these machines but it's the Sony KHS-130A.
The sled issues were down to the sled itself being slightly misaligned which I have now sorted. The Laserdisc was also rather warped and the outer edge plays with distortion on both sides.
I also forgot to change the capture to 16:9!
Really hope you enjoyed this one and lots more coming up.

Thanks for this video, which inspired me to do the same repair to my LDP600WS, successfully.
I ordered from the same seller you did, delivery of a (definitely used!) laser took about a fortnight.
My player, like yours, was a different design to that shown in the commonly-circulating Service Manual - it looks as though we need supplement IMS 92-006 "Mechanism Modification" for that, but I can't find that online...
The transplant was successful, but I offer a couple of observations.
It's not actually necessary to detach the plastic toothed rack from the underside of the laser sled before lifting the sled out of the player - a little judicious manœuvring allows it to all come out in one piece. The rack can then be detached from the old sled and attached to the new with ease, and the whole assembled block threaded back into the player.
The 'collars' at each end of the slide shaft (also not shown in the manual). As you observed these are eccentric, and seem to be so to provide a degree of adjustment to the position of the slide shaft - there is a slot in the one to the rear of the player, to allow it to be turned. In my player, the rear one was held in place with a dab of glue, presumably added after some fine-tuning at the factory. So if anyone else is following this procedure, my advice would be to make a note of the rotational position of the back collar before dismantling - I took a photo of the 'half moon' visible through the collar - and try to restore it in the same position when reassembling.
Hope that's useful, once again thanks for the video, it would have taken me five times as long without it!
That's some great info there and certainly something I'll take on board in the future. So glad it helped you out too. I did wonder if they were used or new/old stock!
Fantastic repair and player ! Think this one may have been built but Marantz in Japan . If the serial number starts in MZ it is .
Thank you. That's really interesting - the serial on my machine starts with MZ so that fits! Very interested to learn more on the Marrantz link. Many Philips higher-end machines were rebadged as Marrantz and looked really good too as they tended to be black with gold emblems
@@MrBetaByte That’s right . Philips owned Marantz From early 80s right through till mid 2000s . Was a great era in my opinion as Philips invented CD and laser disc . So marantz came out with some nice cd players including the bullet proof swing arm laser mechanism CDM4 - CDM9 . A lot still working fine to this day .Your actually lucky thatKHS Sony laser worked for you . A lot don’t even new out of box .
@@troyconnolly9053 I had forgotten Philips bought Marrantz. I agree, it was a great time for Philips, maybe not so much with the VHS machines with not so great video quality and then the Charlie deck which was a fun one to repair (I must try and source one of those for old times sake!). The design of the CD players was really so good - I remember a story of a customer shaking a Philips CD player hard claiming something was loose! That must have taken some effort but blimey! I do think I was very lucky with the Sony KHS in many ways and it's been so solid and has played several discs now without any issue at all. A really very solid machine.
HI, Alex. Nice repair. This machine is using a SONY laser pickup KHS-130A. These pickups are normally used in the Sony MDP machines which i used to service back in the days. We normally use to raise/adjust the laser level and get the pickup back up and running which used to do the trick. You should keep the old laser unit it may still have some life in it. Good Video...
That's a great tip. I can't believe I didn't actually say what the laser unit used in these units is and as you say it is the KHS-130A. Lots of searching to find the 'cheap' one on Aliexpress. My question was more where an earth is that unit sourced? It really looks like new old stock. The Philips was shutting down from no laser detected - which to my mind suggests the laser has actually gone bad but would a laser level issue give the same result?
I've just updated the thumb- feel so daft for not saying what the laser assembly used in these actually is! Thanks again for this, it really is appreciated.
@@MrBetaByte The laser level goes weak in operation along with time. There should be a small adjustment pot on the laser itself that can be turned counter clockwise slightly which will increase the level of the laser and make it work (if there is some life still left in it). I had a Sony MDP999 which came from Japan with exactly the same fault (No LD/CD rotation) after adjustment everything fired up and worked perfectly. The Sony MDP999 is very special and heavy unit (30kg) and I still am using it. I hope the info helps... All the best.
@@Televid4 That's really worth knowing and thank you so much for sharing - really very much appreciated. I'll have to test the old one now... 😊
Are you able to point out where in the player this raise/adjust the laser level potentiometer is positioned?...
Thanks in advance.
Edit:
There isn't (as far I can see/find) a small adjustment pot on the pickup module itself... :-(
The video of that LaserDisc has a lot of dropouts, which isn't unusual for that title.
"Eraser" for NTSC North America, replicated by Sony DADC USA, is a notorious rotter.
That confirms what I thought - thank you so much. The disc itself looks pretty good but the drop outs are so bad in places but are fine later on through the disc - I would have thought it would have been the other way around.
Hello, very interesting video. I've an LD Philips CDV400 that doesn't read disc. I've tryied to regulate trimmer and other things without success. I think that Pickup laser it old or broken. Kindest regards 😊
More than likely it's the laser unit but it does really depend on how good the rest of the machine is.
Hi there. Did you having cross talk issue on CLV laserdisc? Do you know where is the tilt adjustment switch? I cannot find it on mine. Please help.
No, not had crosstalk issue on CLV disks at all. I have to say I'm not sure on the tilt switch location - do you have the service manual? If not let me know.
I once exchanged the complete (Plastic) Laser Unit on a real PHILIPS LaserDisc Player. I have to research what Manufacturer this is.
It's a Sony KHS-130A but I am wondering where this has come from - it looks new old stock. What do you think?
@@MrBetaByte ORIGINAL PART extra on the box makes me rather suspicious, but nowadays you have to take what you can get anyway.
In the workshop I only ever got undyed cardboard boxes without manufacturer imprint but type stickers or stamps.
@@TTVEaGMXde Exactly what I thought to be honest. I really didn't expect it to work but it's doing great and I've played a few discs on it now too.
hi there, Could you advise where did you get the laser pick up?
Hi. The link to the laser assembly I bought is in the video's description. It's on offer too at the moment. Hope this helps and good luck.
