Fantastic video Roger. I can see the hours spent on that device. Very interesting. Well done 👍
Thanks Vince. That's praise indeed coming from yourself. I really appreciate your support and feedback. Thanks!
You guys are both awesome UA-cam repairers I could watch both channels for hours. Thank you and keep up the great work
Spending £100 on the player, just to give us a fab video, well done and thank you.
Awe thanks so much Mr K. I really appreciate that. I do keep my eye out for Interesting stuff nowadays, I have quite a stockpile yet to get through! Hopefully more to come. Thank you so much for your comment.
That was a roller coaster of emotions. Strangely enough, I'm most impressed with your trademark epoxy-as-screw-boss repair. Quite "simple", but it never occurred to me to try it before I saw you doing it on a previous video.
Thank you K.P. it never occurred toe that was a trademark LOL. I'm not sure it had occurred to me either until the Amstrad either! It seemed to work better with the Amstrad but it could be either the epoxy or the plastics were different. Which reminds me I need to get some more putty. Anyhow I'm so glad that you enjoyed the video. Thanks so much for your comment.
Had to watch a second time. This repair was definitely a roller coaster. I can appreciate all the effort and sense the will power in not giving up.
Wow watching repeats is a compliment. I saw another one of these go up on ebay and was a bit disappointed I missed out as I'd like to have a go at one using the lessons learned from this. Somewhere I do have another laserdisc player so there may be another similar video some time. Until then thanks for watching the repeats! And for your kind comments.

Funny how it kept getting worse the deeper you went, but you kept with it and amazingly you got it to a working state so congrats!
Thanks nhsadm. You are absolutely right it just got worse and worse as I went along. It took me weeks in real time. Quite rewarding in the end. Thanks so much for taking time to comment. Really appreciate it.
I watched the entire video start to finish. I am very grateful of your perseverance. It was very satisfying to see the thing work again even if it needs to be recycled. It was a great sense of closure. Great work!
Thanks quicksilver. Glad you enjoyed the vid. It took me several weeks of my spare time to fix so your kind words are very much appreciated. I did sell it on eBay in the end (as faulty for parts, and for less than I paid for it) so perhaps it lived on for occasional use. Thanks again for taking the time to comment. RTR
Very interesting. I never thought you were going to fix it. Absolutely first class well done.
Thanks Richard. I must admit I had my doubts too, by far the most advanced repair I have done. I am glad you enjoyed the video. Thanks so much for taking the time to leave a comment.
I admire your resolve and commitment to finding a solution, Sir. Well done.
Thanks so Much daffy.... it was quite the challenge, I had it on the bench for a very long time let me tell you and I so nearly gave up. Thanks for your comments. Kind words like these keep me going at this stuff. Cheers!
You've done it, manage to run it. Big, big applause.
Thanks so much. So glad you enjoyed the video. Thank you very much for your feedback.
Really impressed you persevered with this one and managed to fix it. It would have been good to see you do that final test and hear your reaction 😀 You must be been pretty chuffed?!! Well done on another great video, looking forward to more repair videos.
Thank You Mathew . Yes unfortunately the camera wasn't running at the eureka moment. I had so many hours of "wasted" footage that I got into the habit of not recording everything. I wish you could have seen it! and Thanks again for your continued comments and support.
@@RetroTechRepair Do you know, I kind of guessed that what might have happened. It's hard enough debugging electronics, if I had to film it too it would be a lot harder. 😆 I wonder how many UA-camrs do a "take 2" with slightly fake surprise and delight at that moment (probably a lot).Also it's nice you always take time to reply to messages of support. Thanks for taking us on your retro tech journeys. 😀
@@matthewbeeson5612 you are very welcome thanks again to you too. Yes I'm sure there's some fake surprises here and there
much respect for that repair. you never gave up
Thanks Alieu. I admit I did once give up, but I returned for more!Tough repair, but I am very grateful for your comments. Comments like yours may it all worthwhile!
Perseverance pays in the end. Well done for sticking with it and making an entertaining repair video
Thanks Simon, so glad you enjoyed the video. Thanks also for leading feedback I appreciate you taking the time to do that
it just shows, that sometimes its worth just struggling through to complete a project no matter how hopeless it seems, good job!
Thanks Raccoonus, Yes I did get a tremendous sense of achievement having finally fixed it. Thanks so much for your comments
Great repair tutorial. I would usually think a dead Sony player would usually be a bad pick-up or a stretched loading belt but I guess you proved me wrong.
Also, just clarify a minor thing; this player will only pass PCM or DTS through the optical digital output. If one does want to output AC3, a mod will need to made to this player to add an additional circuit board and an RCA jack.
Thanks David sounds like you know a lot about these players. I'll be honest I thought it would be the loading belt too when I first read the eBay listing. A quick low cost repair I thought! How wrong was I. Good info on the optical out too. Thanks. As you can probably tell I'm not an expert in these repairs, just trying my hand at fixing stuff. I learn a lot from all the great comments, so I really appreciate you leaving such detailed feedback like this. Thanks so much.
@@RetroTechRepair At this point, we're all learning the hard way to be repair techs out of necessity w/ the lack of repair shops these days. Especially with LD players, we're never going to see a renaissance like the turntable so every player that can be fixed should be fixed so we can still play this old software. Luckily for me, most of the issue I run into are either loading belts, cracked gears, or dried up grease locking up the mechanism so they are not as difficult to fix. However, I have acquired some DOA players that I can practice on seeing if I can fix and your repair tutorial gave me some ideas. We'll see how it goes.
And in regards to AC3, I do specialize on doing these mods. Probably the coolest thing in the world to upgrade a pre-1994 player with a new sound capability.
@@MovieGuy846 good to know. Thanks so much I do fancy trying another some time but need to clear some space first. I'm fighting the urge when k see a good candidate on eBay. Keep in touch glad the video helped I'm sure you have experience I might need as I tackle more players
I have that same player with more or less the same problems! Thanks for the inspiration to try to fix it!
Hi Tadeu that's great. So glad you found the video useful. I learned a lot myself if I do another I'll be VERY careful with the plastics. You might get lucky, mine wasn't packed very well for shipping so some of the damage could have occurred on its journey to me. Anyway thanks so much for your comments and good luck with the repair.
Amazing repair! So glad you didn't give up on it.
Thanks Will, really appreciate that. I've been working on a pioneer machine at the moment but I'm not convinced that one won't beat me! Thanks for your kind words
Well, that was an epic fix! When I saw how complex it was inside and all the plastic falling to bits I was a tad pessimistic to say the least, hats off to you mate 👏
I remember games in the arcade such as Dragon's Lair had one of these in (usually Pioneer I believe) and they are very temperamental.
Fantastic watch, one of my favourite uploads from yourself. Real shame both for you and us viewers that "that" moment wasn't captured but I can imagine it was euphoric 😁
Thanks Skyway73 and thanks again for your comments. Yes Dragons Lair and a few others used these.... Amazing stuff back in the day. I have seen industrial players for sale, but I played these games only later via Daphne emulator. Glad you liked the video it's my favourite to date though sadly not my most successful perhaps it's slow burn. It was quite exciting when I got it going. Thanks as ever for your continued support. Roger
Thank you for this video! I have the US version MDP-455 I purchased new in the early 90's. It hasn't worked for years. It won't read discs. I've opened it up but don't have the skills to repair. I suspect the problem is in the laser mechanism. I have a bunch of opera discs that I can't find on more modern media or they are very expensive. I think I may look for a working player instead of trying to repair after watching your video!
Hi Tom, Thanks for your comments. Sorry the video didn't help you repair your player, but perhaps it helped you decide on a course of action. These players are getting expensive now. This was my first but I was very impressed with the format for its years and would like to find a good one. Thanks for taking time to comment. I value that.
I respect you that you were able to fix all this and that you have a lot of patience. And well explained. great 👍
Thanks Audie, it was quite the battle. Glad you enjoyed the video! Thanks so much for your comments
That was excellent. That must have felt great to get through all those hurdles and persevere. Really enjoying your channel. Thank you for the great content.
Thanks briancoulomb. Monster repair took me weeks! But it was quite something when I eventually got it working! So glad that you are enjoying the channel thank so very much for your views, feedback and comments.
What an awesom repair. Well done
Thank you James. So glad you enjoyed the video. I am quite proud of this one, shame the vid didn't get a few more views, but comments like your own really help. Thanks so much fo r the feedback and taking time to comment.
another great video and have a great day
Thanks Joseph. I am glad you enjoyed the video. Thanks so much for taking the time to leave a comment. I really appreciate it.
Great fix, excellent track repair, 👍
Thanks so much David. Really appreciate your comments and feedback!
and now that's what I call tenacious or as they say in Galaxy Quest...... Never Give Up, Never Surrender!
Thanks Awal, I very nearly did give up. I appreciate the comments and support. Thats what keeps me going.
@@RetroTechRepair All I can say, I was rooting for you throughout the video and I am so pleased that you got it going.
Thanks @@awall1701
Awesome perseverance well done for your efforts
Thanks G! Trust me, I very nearly gave up. But was very excited when eventually I got it working.
Patience rewarded ... such a shame Sony cheaped out on the structural elements. Epoxy putty and FORMcard can be useful for reinforcing dodgy plastic joints. Keep an eye out for another one ... your experiences might pay dividends in the future.
Plastic easily gets brittle when it gets old and has been thermal cycled..
My pioneer LDP's were no stronger on the innards.. :)
A little low(!)
heat (air gun) can buy you just a little bit of flexibility on old plastic.
Thanks Bill. I was hoping the pioneers may have been a little better. I was on the lookout for one of those. Thanks for the hot air tip, will definitely try that next time.
Superb work good you never gave up .
Thanks @paulb4uk, believe me I very nearly did give up on this one! Thanks for your comment it really makes a big difference to me
Absolutely Fantastic !
Thanks so much for your kind words. Really appreciate yhe feedback!
"Well done Sir ..It was well worth it 😊!! ..Great to see old kit working again .."And now you got a working laserdisc player 😇!
"Just to add I still collecting laserdisc films and enjoy watching them 😊 ..More than bly-ray believe it or not!
"Great vid!!!💜

Thanks Derek, I always had a fascination for laserdisc, but haven't owned one before. I really liked it. I have another LD to repair but it might be a while until I get to it.
@@RetroTechRepair "I'll look forward to seeing that L.D. vid too! ..😉
"Many thanks Sir!

@@dereksewkumar07 you are very welcome
Admire your staying power. How many times did that repair look dead in the water?
Thanks Stuart. I think I lost count how many times I gave up, more than I admit to in the video. The whole thing took me about a month of evenings and weekends with a LOT of video to edit down to 30 mins. Thanks so much for your comments. It's the feedback tat keeps me going and I am very grateful for it.
Really nice work with this one - you would have had this one completed if it wasn't for the dodgy plastics! Well done and thanks for showing us.
Thanks so much, for the compliment. When I bought it I thought it would need was a new belt! How wrong was I? Those aged plastics were a real shame because otherwise it was a nice thing. I was actually quite sad to see it go (for less than I paid for it too!). Anyway thanks so much for your comments I really appreciate that.
That was so much fun to watch 🤗
Great to hear HooverLux, so glad that you enjoyed the video.
@@RetroTechRepair I’ve been binge watching your channel 🤣.
That's awesome hooverlux I could definitely use the views! Bit of a mixed bag but I learn as I go. Glad you are enjoying the content. Thank you So Much for your support
@@RetroTechRepair What appeals to me is that I’m exactly the same, all my videos are looking at stuff for the first time and trying. I’ve picked up so many tips from channels just like yours, My Mate Vince and so many others too. The whole thing is like an Open University course. Thank you so much for your channel and every other like it, keep going, keep trying and keep learning. 🤗
Thanks so much hooverlux
perseverance paid off
In the end it did. My most complex repair to-date, a great challenge and a great sense of achievement. Thanks so much for your feedback. I genuinely appreciate you taking a few minutes comment. Thanks so much
@@RetroTechRepair really good to see that your couldn't let it be. It's that tenacity that delivers results with this retro tech. Real shame about the brittle plastic.
Good information
Glad you found it informative. Thanks for the feedback
nice work
Thanks
Great repair, another one saved. Shame time is taking it toll on the caps and plastics
Thanks, quite a challenge that was. I have another older LD player yet to do it will be interesting to see of its better or worse. I don't think we will have too many of these players left soon. The plastics are so brittle now and they have an awful lot of caps. Thank you so much for your comments.
Wow, what an amazing repair, and quite the roller coaster. BTW, for dealing with broken plastics, there is a technique that I and many others have used successfully. If you combine cyanoacrylate (aka super glue) with baking soda, you end up with a surprisingly strong compound that you can use to join broken plastics together again. In fact, this technique works so well that you can actually use it to *re-form* missing pieces of plastics in many cases. The UA-camr "Tech Tangents" does a much better job of explaining this than I possibly could, and he demonstrates this technique on several of his bits of seemingly irreparable plastics. Search on UA-cam for "tech tangents plastic repair" for that video.
Thanks for the feedback and the tip, I'll definitely check that out. Glad you enjoyed the video... I was riding that roller coaster quite a while.
Wonderful
Thanks Dieter. I am glad you enjoyed the video. Thanks so much for your comment. I really appreciate it.
Good job
Thanks
Impressed!
Thanks WGFA think it's my best repair yet. I appreciate the feedback.
EH Nice video super sophoritic voice stop doubting yourself your good at this fix it till it is plain broken completely then give up its good to see your video its very watch able and interesting keep up the good work oh yes great idea using the nail varnish much much cheaper than solder mask and removeable with a bit of nail polish remover or acetone the former being cheaper also great work you now have a new subscriber one last thought if your honest with the buyer how you repaired it I think you could still sell it but that's your decision after all it's a working laser disc player
Hi David, thanks for your kind words. I am glad that you enjoyed the video. I did sell the player on, but as spares or repair and with an explanation it had been previously repaired and might not last. I lost a bit of money on it, but that's life. Thanks also for the sub. I really appreciate that.. Finally thanks for your detailed comment. I know that commenting takes time, but it really helps keep me going and probably helps the youtube algorithm find the channel too. Thanks for giving up some of your time to help. Cheers!
So nice
Thanks
he just happened to have some nail varnish erm ok we believe u hahahahahahaha
LOL, OK I admit it... nice aqua colour though don't you think?
@@RetroTechRepair suit u sir opppfh
@@80sretrogamer I look Scorchio!
@@RetroTechRepair 😂😂😂
Holy sh?! I can’t believe it! Great job
Thank You Hunter, I have to admit to being a little bit proud of this fix. Thanks so much for your feedback and support. Really appreciate it.
Unreal trace repair without a microscope
Thanks Jamie, I should put one on my shopping list. With my very honest eBay descriptions, I tend to lose money on these repairs so I need to managed my acquisitions carefully. I used a loupe magnifier when I'd taped each section of wire in place and again after soldering, but it took me probably 3 days of my spare time to get the tracks repaired. Thanks for you comments BTW... very grateful
That belt fixed the clamping issue. Now the motor won't spin the disc. I'm about halfway through. Can't believe the motor is burned out. Hoping there's something that is preventing the motor from spinning. The lase is em
emitting Light. Also did a full white grease relubricate... ( mine looks to be a very similar mechanism - MDP-455
Good luck with the repair. They are big complicated beasts for sure. I might have a go at a other someday.... till then thanks for your comments. Really appreciate it
@@RetroTechRepair any tips on the motor spinning issue? Moves freely with or without a disc. All aligns and no binding. It’s in such nice shape and hate to give up. I’m rather “stuck” at this point.
I really enjoyed that one
I'm glad Vince told us about your channel
Thanks Jason, that one was a battle I have another laserdisc player ready to repair
Glad you enjoyed it
Hi Roger amazing fix and Very Well Done, you have the Patience Of A Saint, just taking that apart would of given me nightmares lol. Great to see you are a fellow Cat lover like myself, i have three and wouldn't part with them, fantastic little companion's. Not sure I like your colour of Nail Varnish though, maybe Red would suit you better lol 😂😂👍Mick.
Thanks Mick. It did test my patience a bit, I was overwhelmed when I saw the complexity, but I did have quite a lot of money in it, perhaps that was the motivation :) "Bones" AKA "Simon" kept me company through it. We adopted him as an adult, but he's very lazy. I'm a cat person too and they have kept me going through a number of hard times. We only have the one due to space, but I think he is the 5th one I've had. You are the first person to comment ton his guest appearance. I think he is at the very end of one of my other videos too, but I forget which one. As for the nail varnish what can I say, they had sold out of green so it must be very popular in Scarborough. Red wouldn't have matched my lipstick I am afraid. As ever thanks for your comments. Always a pleasure.
Wish I had one
Sadly this one has left me now. I have another LD player to repair at some point.
Hello! The video has been useful to me.
I have the same player.
But I have a big problem. When I turn it on, there is a noise like a motor turning. But the disc doesn't spin.
I really don't want to lose it. There are very few...
Please, if you are there, and can help me, send me a signal!
Hello Woppox. I am here but unfortunately i am not an expert in these repairs and these machines are very complicated so I am not sure I can help much. There are several motors controlled by several microprocessors. You probably need to work out which isnt working. When you put the disk in does the sled move, the laser move up and down and the disk lift off the tray.
Do you remember which were the values of the capacitors you replaced ? I've the same to rework, but it cracked a lot during the shipping...
I'm sorry I don't remember and I don't have the player anymore
I’m trying to fix my pioneer cld-604; i need a ribbon cable but can’t seem to find the right one
Sorry I'm afraid I can't help, I'm just an amateur trying to fix random stuff. I myself struggle with those flex PCAs and ribbons. If you find someone pop back and let me know
Hallo, iI think the 650 is very similar to the 740 D. My problem is the player doesn't play the discs. We had to repair the tray because it does not work propperly. Now this was fixed we recognized that the player does not read the discs. Any advice for me?
Hi thanks for your question. I am afraid I don't have any advice. I am far from an expert in these repairs. I have a similar problem on another machine I have, but haven't yet managed to fix it. One day if I do I'll post here and maybe it will be useful. If you find a solution let me know.
In the meantime thanks so much for your question, hope that you enjoyed the video
I’m trying to fix my d604 player and am having an extremely difficult time finding a 23 pin flat ribbon cable that connects to the laser lense assembly.
Any suggestions on where I could find one?
Sorry but I really don't, this was my first repair attempt of an LD player and I might not do another for a long time. So sorry. If you do find a source pop back and let me know. Thanks again
I have a pioneer LD player and all LDs stutter or have like a random hiccups when I play them. Nothing wrong with the discs. What can be the issue for this? Lens or something else??
Hi there, thanks for your question. Sorry I do not know, I'm really no expert in these repairs. Thank you for asking. Sorry I can't help.
All sony products around that time had weak abs plastic discmans were the same
Yes the brittle plastics were a real shame. Honestly I would have had a nice player on my hands if it were not for that. Thanks for the comments I'll remember that if I do any more Sony products.
I have the same model and the tray doesn't open. It power's up, but the tray doesn't open. Can you help?
Hi there, thanks for your question. Sorry I can't help, I'm really no expert in these repairs. Thank you for asking. Sorry I can't help.
I got a laserdisc player that didn't work the pioneer 2400 they come from school's
Sounds cool... did you repair it yet. I love the format and hope to find a player worrh saving. Thank you so much for your comments
Wonderful
Thank you
Wonderful
