@Vlad-ui4ry Hello and thanks for watching the video. Indeed I put up the video to help other people out as you never know when it might come in handy to know.
Wonderfull to see this again after 26 years! This truly was/is true example of how promotional videos should be made. Still have to visit though, but will be doing so soon.
Hola, tengo ese mismo reproductor, el problema es que con un disco Laser Disc al principio detecta el disco y la cara del mismo, pero a la hora de empezar a reproducir en la panatalla aparece "Open" y lo expulsa la bandeja, ¿Que puede ser? en los otros discos no me lo hace, funcionan sin problema. Muchas gracias, un saludo.
What video card do you think would be best for a AT system? Recently refurbished a 233MHz Pentium MMX system and trying to find a good video card - My first through was a 3DFX card but finding one within my budget is rough - so I thought Riva 128 but then I read that AT boards sometimes do not support cards of this nature because of the 3.3v requirement from the PCI slot. I feel like I'm going to end up spending as much on random video cards trying to find one that works as I would have on just getting a 3DFX Voodoo 2.
Hello. There is nothing really beyond the videos. In some cases, it can be the tilt adjustment and many more adjustment pots in between. You will need the proper calibration gear like an oscilloscope and remember if you do source the laser Disc adjustment/ reference disc. It's usually a one-way road ( the disc can be destroyed by the calibration!). I have replaced or swapped lasers with more success from one drive to another. Now, one commentary on my videos pointed out that you need to calibrate the laser.. well, technically, you do. But we ain't got the gear in most cases. If you can find an expert, you will be better off. And remember, live voltage is inside these machines and pretty exposed, so exercise caution ⚠️!
@@DRCHRISTIANMD dont have such gear and the experience to try this. the machine plays other discs just fine and those failing seem to be in perfect condiction both sides. maybe cleaning lens and belt will work?
@paubayes2002 could be disc rot on the said discs. Not always visible. I would leave be if your not confident. That said a new belt can help some times and cleaning the grip ring. I would be vary cautious about cleaning the lens and if you do only use distilled water. I don't use the alcohol based stuff myself on them.
@@paubayes2002 no idea TBH. Not sure if a service mode will help with the issue. Most likely simple causes like the belt,grip holder, or dirty lens. The service manual is online and explains how to enter service mode.
@RetroReels Probably best to change all the capacitors on the PSU. That said I found the PSU and it's traces to be very fragile. I am also not by any measure good at soldering!
I have had the power supply re-capped and checked - still H2 error. Anything else worth looking at? No visible damage on any of the main board or dry solders etc.
My first PC had been a 386sx 40 MHz NEAT AT. Had to buy a copro. Why? The computer had to do 2D CAD (STRAKON by DiCAD). It had Hercules paperwhite 14". Had to buy a Speedstar 24 and an EIZO 9080i as well. Ready to become "The CAD Pope" when I still was a student. I will rebuild an Intel i386 20 MHz soon, adding a copro. Had been given that board from an engineering office these days when i486 came around. Curious if it can be brought back to life with scsi and STRAKON running on it. DiCAD is still around AFAIK.

Ok 👌. I was looking at this laserdisc player. 1992 Pioneer CDL 1750 PAL/NTSC CD CV Laserdisc Player. It has a digital optical in the back but it doesn't have AC3! So does this mean it won't be dolby digital sound? So i really need to find a laserdisc player with AC3 on the player
Also I'd only be using a optical setup? With that optical cable going in to my bose 5.1 surround sound system? So do I still have to get a laserdisc player with a AC3 logo on it?
@worzysp1 pretty darn good. On a properly setup 5.1 system the stereo surround from the optical will give you decent range and surround. The quality on the disc is very good compared to some modern stereo software.
My CLD-950 (ssided) player wasn't getting to the end of CAV discs, but after taking out the rail, cleaning and re-seating it, all CAV's are playing nicely now. Thank you for posting this.
Their workstation boards from that time period had a rather odd construction, which used a mezzanine card to carry the CPU. And the PowerLine 450DE/2 DGX was made available with NeXTStep/86- it was actually the first computer announced to ship with that OS.
Yes, indeed, I had a few of them style with 486 SX for scrapping back in the late 1990's. I thought I kept one of the riser cards but couldn't find it for another video. 😉
THANK YOU SO MUCH MY FRIEND ! - The CD drive unit is exactly the same as in my NAD C541i...and it seems the load / unload drive belt for the draw is a common problem. It should ideally be a new (square section ) belt, if you can find one. To get at the belt, the trick is to withdraw the tray completely by moving outward the two butter-fly like plastic clips at the front of the draw, as you very kindly pointed to in the video...I just could not work it out till you showed us !!!. Then you can slide the new belt over the two pullies by raising the little black plastic cover a little, the one you said was just to cover the pully wheels. No need to actually remove the unit at all if you are very careful!!! Hope this helps someone?. Long live RU-vid !!
@@DRCHRISTIANMD It actually influenced a purchasing decision for a "spares-only" laptop just half an hour ago! Don't worry, I won't whinge to you if I screw up 🙂
Also, VLB will RUN at the CPU FSB Speed, which means up to 50Mhz on 486 (remember the DX50?) on Pentium there are workarounds as it is true not all cards will work well past 33MHz, got many a VGA card killed thanks to that on DX50 systems, not on DX2's though as those never went past 40Mhz FSB speed.
My 468SX rig had VLB, just the slot, I didnt have any hardware to use it with, but even being 12/13 yo at the time in the early years of the post-socialist Poland, i was baffled how jerry-rigged that looked XD also having no access to any resources or information on PCs in general, not to mention something so specific, i figured out VLB stands for Very Long Board - made perfect sense :D
Thanks for watching. Indeed the VLB/VESA Slot was a stop gap solution to a problem that was soon resolved with the PCI Local Bus. At the time it was needed to improve performance on HD transfer speeds and VGA performance. I think Jerry-rigged is not far from reality.
Hi I’ve just bought a d925 with a bad belt however in the hands of the delivery company it’s been crushed. Could you tell me if the upper slide for the laser should be completely flat? Mines bent downwards and fouling the drawer!
found video useful and repairing pioneer cld 925 with brand new laser but have live video and some new problems that figuring out , but slowly winning , also brought the satlink st-5150 , i find it to be when arrives in few , no days to be useful when repair in the kitchen before i connect to the THX cinema
Just here cause my CLD-2950 broke down, laser issues. Around IC902,your vid seen at 10:15 min,Left of screwdriver, I found couple of bad capacitors, very leaky and totally off specs. C976,C970,C967,C987,C968. All were the brown ones, as there are also black case capacitors, those seems to age better.Without measure equipment you even can spot them due to corroded leads of them. So really leaky. Now audio-CDs are working, but very pick when touch the case of the player, it skips easy, LaserDisk, still not, so have to digg further, I do hope not adjustments of the laser cause lach of service remote and special LD-s .Damn, I am said. CLD-2950,was..., a great player, even already some degrading LD-s it still would play them, when other LD-player would reject those bad disks.
What wrong is you and not the laser pickup. You need the tools to align it again and a scope. Not going to go into this but laserdisc player are not like cd players and are much harder to do when come to laser problems.
Maybe, however I have taken laser assembly from various machines and swaped them around to no ill effect. They where calibrated at the factory and would require fine tuning on a n individual player but as you say you need the laserdisc to align the unit. Thanks for watching.
@michaelmitchell8218 you need to stop making yourself feeling proud and boasting your "skills" here, if you know how to fix them then why you don't make a video about repiaring them? Saw you in another video claiming the no disc error laserdisc player video making the same boasting attitude there. And don;t criticise DRCHRISTIANMD here, at least he done a well-done job.
@@BackupChannel-i9c you want to understand I’m not going on about my skills, also I don’t have time to do a video because I’m busy repairing fuck ups because of people like you who think they can repair. It takes years to learn the skills you need to do this stuff. Laserdisc is not an easy one unless you got the tools for the job and an oscilloscope and know how to use it. Laserdisc is nothing like a cd player for setting up and even see videos of that being done wrong. These players are old and need a service and not someone just trying this and that. If you want to repair stuff like this and then learn electronics like we all had too. Yeah I got skills but took years to learn, not a RU-vid video and talking of RU-vid videos, do you know how many people are killed a year playing around with electricity because of what they see on RU-vid videos ? And also it’s not a well done job it’s called a fuck up because it don’t work and all because he don’t have the knowledge or skills to do it. With all things like video, cds and laserdisc,etc you need an oscilloscope and know how to read RF signals and eye patterns, etc to put these things back in alignment. Pioneer got an online video showing you all about laserdisc players and how to repair them if you look about. You think what you like I’m just trying to stop people making things worse or end up killing themselves playing with high voltage.
@@DRCHRISTIANMD the laser can be used once you recallibrate properly with an oscilloscope. You can watch Chad Page's uploads regarding a Pioneer Laserdisc Player Service.
Just wondering as I have this model, is there an online community of people like yourself with such knowledge and expertise who can repair LD players as I’m in Manchester and struggling to find anyone.
Hello. Yup, Laserdisc Forever on Facebook has a large international community all about Laserdisc Player and discs. Much appreciated you watching this RU-vid video and the lovely compliment 😊.
Don't want to impose. Is there any way to get in contact with you regarding a no disc error on a CLD-1850 ? Seems like all meganisims is funtioning however disk refuse to spin. Btw. Im in Ireland and seeing that you are the leading authority on these machines, naturally you would be the first line of contact.
Hello, and thanks for watching my videos. I wouldn't have any spare parts for this machine anymore. My hunch is either a loose cable for power, maybe a bad power board, or simply the motor has died. Have you tried a CD. Beign smaller, it might spin up?
First of all, thank you for perhaps the most informative videos regarding LD players. Stumbled over your videos and would highly recommend each and every one of them. Being a complete novice, and only recently obtaining one of these players, I unfortunately ran into a issue where it cannot recognise any disk that is loaded. No disc error. Opened it up and it would appear that all mechanics is functioning Tray opens and closes both for CD and LD. Laser clicks twice up and down and I can see the red laser active. Laser pickup looks to be working as it moves on the rail. Clamping of disks appears to be functioning. But there is no spinning from spindle. I manually tried spinning it and it spins freely without resistance. No luck. Bands seem ok as well. Any ideas or options that I could further check perhaps ? Unfortunately I don't have the luxury of a doner machine or any technician here in Ireland 😉 that could take a look.
Probably still got some in a draw, oh no its an i386, when i built my first PC my work colleague said this 386DX40 is better to have than the 486DX33 i said er no thanks, i wanted one for playing Alone In The Dark
The 486DX has a maths coprocessor, and the 386DX doesn't. When it comes to architecture on the 486 v 386, the 486 could have VLB or even PCI, so overall, it is a better choice. I use and still use the 486 for the odd games. I only have one working 386 ( AST Premium 386, as per other video), but I generally only use 486 class. Bit more speed and user-friendly architecture.
Yup these are the FPU and the AMD is the CPU near the end. If you go watch my video on the AST Computer 386, you will see them in action. Many thanks for watching. 😉
I had a problem with my laserdiscplayer with a similiar motor sound. Simply fixed it by placing a piece of plastic under the white rail to raise it up abit so the gears could grab on to it. Works perfectly now😅
i have one, would it work as a output if i don't have the pci and only the isa? or is it being connected to pci a hard requirement for it to output anything
Exactly what DrDuron said 😉. Great to save another from the landfill. Thanks for watching my video and hopefully another one at some stage will help you again.
