Most common fault other than bad craps

@@12voltvids I guess i've just been lucky, or unlucky? lol. I do have an old CRT apple monitor I'm gearing up to try repairing maybe I'll find a reflow requiring situation in that one! fingers crossed, lol.

They start at the same speed as a vhs head drum. 1800 rpm. Mini DV spun 9000 and digital 8 4500. Most hard drives 5800.

I also have a wonky MDP-455. I've sunk close to 10 hours into trying to fix it and haven't really gotten anywhere. In fact, I made it worse last time by accidentally removing the laser's drive belt. This video is giving me the itch to give it one last ditch effort to get it working, though.

Seems like an odd inquiry 🤔. Blade Runner is a pretty common LD title on virtually all its iterations. Anything specific you were looking for?

Amazing Stories. Tv series NBC 1985-87 I have some of them on LD. My favorite episode is The Family Dog.

I agree on the challenge aspect of broken units, too. I would usually prefer to buy one that is not working, but fixable, than one that works. I will attempt to fix it. Someone else might just throw it away. Let _that_ guy take the one that "just works." I fully re-cap just about everything I get, or _at least_ the power supply and servo sections, just as much a matter of course as wiping down the top and front panels. A lot of times, after recapping, cleaning, re-lubing, and exercising the mechanisms a few times, they just spring to life -- whether they were previously working or not!

It's usually not hard and very cheap to find replacement lasers for Sony CD players, if it's not very old. KSS-213A-B-C-D-E-F are the most common and dirt cheap on ebay and Aliexpress, sometimes you can find NOS originals, but the third party ones are usually not that bad either (even if they fail within 2 years, it's so cheap it's worth replacing it again). I don't like the plastic suspension of the lens, though.

I have many laserdisk only releases. Mostly music related.

I agree it would be awesome to see

Well that's because I fixed it. Duh.

You can send it to me. I will watch it for you.

@@12voltvids no shit really you fixed it?.

@@tedbell4416 no actually it just started working on its own. What do you think? I didn't tell you exactly what the problem was. Yes the connections on the adjustment pots a few of them were cracked for sure and the adjustment trimmers himself needed some cleaner on them. But the two I sees that I resoldered on the board one of them the little flat pack ic several pins were cracked solder. It did need dialing in too but once I got it dialed in it played perfectly and it's playing perfect now spins up immediately starts playing the desk no hesitation. that's one of the reasons why I'm more reluctant to fix that old pioneer 10:30 with the broken gear on the loading Trey it's because when I can pick up a really good machine cheap and get it going then why would I spend money to have a gear 3D printed for an old basic machine

@@12voltvids good job 👍

Yes they sound good. A laserdisk player has all the same digital audio circuits as a CD and were generally high end players.

I was a little concerned at first. Then it worked.

Never had a bad pickup on a laserdisk yet.

Solder on the ic.

That why only the tip is tinned.

I don't advise tinning the tip either. The nature of solder will more likely than not mean the whole length is partially soldered. It is almost unavoidable.

​@@martinda7446 Yes, I know it's very hard to solder just the tip, capillary effect can easily suck up the solder between the strands much farther than you would want, even way under the insulation if you keep it melted for long enough. Soldering with high temp very quickly might do it, but it's fiddly and not very repeatable.

@@martinda7446 it's all about heat. Do it quick and with the heat turned down and the solder won't wick in that far. 2mm perhaps.

Many of the one pristine jackets have corners chewed because i have a stupid cat that like to chew things. Thinks it is a 🐕

The wavelength is the same as for CD but the optical pickup is totally different. First of all it's much larger than a CD pickup, and the traverse that is mounted on also has tilt ability. So it works off of an x and y axis for up and down and side to side tracking as well as a tilt axis to align the laser up precisely with the optical pits on a laser disc which may not be perpendicular just due to the size of the disc. So if you watch the sled servo assembly you will see that it actually tilts slightly as the movie plays. Physically it's much larger than a CD laser.

Warped play fine. Centrifugal force straightens the disk as it spins.

You're right, it's not up to code. Tinned multistrand wires are very soft, the tension of the screw terminal will flatten it out over time, causing loose connection. A lot of manufacturers in the '80s here in Eastern-Europe did this and those connections are completely loose now. It only takes a few months, but after some years it will be *very* loose.

My guess is because the stranded wire is much more flexible than if it would be if it was soldered. It could allow the weak individual flexible strands to break right below the soldered bit of the wire, with prolonged occasional movement of the cable. But it shouldn't be an issue if the cable has a strain relief of some kind. As with a mains plug.

I breath jazz and bleed blues.

But from which view? Wire or pins towards you? For most non-UK European plugs (round Shuko with grounding on the periphery, or this flat low power one), polarity doesn't matter as they're symmetrical and fits into the socket both ways around.

The European plug in the SONY LD player is actually non-polarised. It is used when the mains go straight into a transformer that will completely isolate the power supply output voltages.The metal chassis will set the ground level reference.

It was the other one on the clamp. Cheap plastic.

Around 5000 rpm slowing to 3000. I have 3 CD video. Robert cray smoking gun, David Bowie ashes to ashes and the flight of the dream team. Very very rare indeed.

I did a review of it.

They've not fake. Real wood just like the es line.

Did you check spindle height?

@@12voltvids Could you advise how to do it?

Do you mean the spinning motor? Mdp 999 use two set of motor. One for ld and one for cd.

@@alanwong3980 if it's spindle height there is a lock screw on the disk Chuck that you losen to adjust. I have just tried adjusting up or down a bit untill it reads. The manual i am sure has the procedure but i don't have it and don't work on enough to bother getting one.

@@alanwong3980 not familiar with that model. Never worked on one. I actually did very lite work on any laserdisk because they were never that popular. Have see. Perhaps 10 in 40 years.

yes I fixed a Samsung blu ray it had a spring in the tray

@@EastAngliaUK plastic parts

That's a CED, capacitive electronic disc. Uses a stylus to track a spiral groove in the disc but unlike a phonograph record where the stylus wiggles back and forth to reproduce the signal, in a CED the depth of the groove varies slightly, the stylus does not actually ride up and down in the groove it rides along the edges of the groove but the distance between the bottom of the groove and the stylus changes which affects the capacitance of the disc at the point where the stylus is running and this difference in capacitance is measured to produce a signal. Was quite an ingenious idea but it also almost bankrupted the company. Did you know that RCA started working on that in 1963. They brought it to market in the early eighties but it already been surpassed by laser optical readout so it died a quick death. Today they are considered collectors items because RCA did what was unthinkable back then they bought all the players back and all the inventory of movies back from the retailers and put them in a giant crusher. Kind of like what general motors did for the ev1. So any of those players that are out there now were collected by people that did not return them because once the program was scrapped and no new movies were being released RCA had a buyback program where a customer could send the player back and the movies back to RCA and they would get a discount on a new VHS purchase. Many people did take them up on that offer, and I know this because the dealer I was working for at the time was an RCA dealer as well as Sony and Panasonic and a few of the players that we sold came back and were traded in on something else. The dealer then returned them back to RCA for a full credit just like they would have if the unit had never been sold and it was a brand new unit. The CED player cost RCA more money and was likely one of the things that caused RCA to not only lose its market share but ultimately end up being acquired by Thompson.

Technology connection did a video series on the CED, it is indeed a textbook example on how to do the wrong decision in every step of the development and marketing of a product.

@@12voltvids Never knew that, And i have A few Of the disc and the one player yet, But as i say it needs work on it, it does play , but only half the Movie then starts over unless its Helped with tracking, Like its Jamming some wheres, not sure, But i used it a few times as is, but Might try getting it Fixed if Worth the Trouble, as i have alot of good Movies on them CED disc.I had this Machine a few Years now.

Everyone knows that multi system equipment were a compromise. They did everything but not that well. Those who were serious in Europe boughy an ntsc player and monitor so they could watch ntsc disks in the best we quality available at the time.

@@12voltvids ha ok cool

I don't even remember it because the camera was off. It would have been either bipolar capacitor or a bipolar junction transistor joke. I worked for someone that was BPD. There were days he was ok and then there were days where everyone else around him was looking for a bus to step in front of. Yes it was that bad. The best day of my life was walking away from that place. It was better than my wedding day and it was better than watching my 2 kids being born. That gives you an idea on how miserable this one person made everyone else when he was in one of his moods.

Not this one. Too good a player

Might show up as some dots of noise on the picture. It's quite hard to make a laserdisc unplayable or skipping. Even ones with severe laser rot are usually playable, just having very bad picture quality.

They usually cause no trouble because the laser is focused deep inside the disk. If the obstruction was really bad you might see it but generally it's not noticeable because remember the video signal is analog but it's FM modulated. so what comes off the desk with his red from the laser is a series of FM carriers which convey the information.

This was long before SACD.

From what I have gathered, Sony seems to have used two different models of NTSC players. One, I think, was just NA -- US and Canada, specifically. The other was for Europe and Asia. I have a Sony MDP-600 and a Sony MDP-A1. It's the same player, except there's a PCB attached to the transformer that, on the MDP-600, just has some filtering and a cable harness that goes to the PSU board. That's the NA variant. On the A1, it adds a voltage selector (the same circular kind shown in this video.) There are so many weird regional power and line frequency mix-and-match combinations in Europe and Asia. 100 or 200 volts. 50 or 60 Hz. NTSC or PAL, or NTSC but with PAL color, etc. Who knows where this player was originally sold, but it doesn't surprise me at all to see NTSC with a European plug on it. Somewhere, that's normal.

​@@nickwallette6201 Well did some research only Peru, Burma and Guyana seem to be 220 volts and Ntsc and they don't seem to use a EU plug either so dk why it has that plug on it, Even if the player was from like Peru I think it would have had a diffrent plug on it

Yeah. The whole key-management fiasco is something up with which consumers should not agree to put. Every DVD and BD disc I acquire goes straight into a computer running AnyDVD HD, and into an MKV file on my NAS. I think I have yet to actually spin a single Blu-ray disc in a player -- even a software player. I never even bought a standalone DVD player or BD player, until a couple weeks ago when I bought an old SACD player that _happens_ to play DVDs.

It's not actually a problem because these things spin so fast that you get this centrifugal force on the disc that flattens it out. when you look at the wobble as it's starting to spin up you would think how the hell can this thing play but it does. It's the centrifugal force in gyroscopic effect straightens the Disc out and the laser tracks at fine. Over the last couple weeks I've played probably 30 discs in this player and they've all played perfect. The best $10 investment I think I ever made I'm trying to buy another one right now but the guy won't take my offer for a broken player.

380V between phases is for 220V phase2ground. The nominal/harmonised 230V phase2ground makes 400V between phases, and 240V phase2ground makes 415V between phases. (With 120° between phases, the trig works out to a factor of √3)

If you are patient, you might find one for free. I accidentally came upon a Mitsubishi, M-V7057 (clone of a Pioneer, CLD-D704) that the seller just wanted a home for. I guess after we talked, he was more than happy to know I was the kind of person he thought it should go to.

I bought another one for 10 bucks

Watch and learn

It's an analog format. The digital audio soundtrack was under 600 meg per side as only 60 min max of 16 bit 44.1khz digital audio.

Bad lead free solder

I think I overpaid

If you ever decide to sell it, I’d buy it…if the price was reasonable.

It's like owning an antique car. Why have an old car? New cars get better mileage, have A/C, etc. Having a classic media player is enjoying part of man's history! Hail LD! Hail Betamax!

I have many movies that are just not available on any other format. Many old classics.
