Tutorial: Repairing A Sony MZ-R55 MiniDisc Recorder
ฝัง
- เผยแพร่เมื่อ 25 ต.ค. 2024
- I bought a Sony MZ-R55 in the middle of the night from someone on Facebook for $15!!!! It worked, but not really. Basically not working. Can I fix it?
I am so not a consumer electronics repair guy. What with my sausage fingers and rudimentary soldering skills. But I do have an Internet connection and a set of tiny screwdrivers, so let's dive in.
Apologies for the sound quality in parts - I am working in my music room on a 34c November afternoon and the air-conditioning is not silenced .
MASSIVE SHOUT OUT TO...
SJM4306 ( / sjm4306 )
CBits Tech ( / @cbitstech )
For their videos on MiniDisc recorders and repair, and their generous replies and advice in comments.
CBits Tech has a video that clued me into the ribbon cable notion ( • Minidisc Recorder MZ-N... )

Very brave of you to do this for the very first time on video. It gives me confidence to try this myself, should one of mine fail. Thank you!
Got my hands on a MZ-NE410 for 25 bucks on offerup, worked all well and the dude even gave me all is 5 discs. what a deal. Minidiscs sure are cool
Dude! En-vy! You scored big time! I got my mz-r35 (just the thing) for 25€, two new batteries (18€), charger (1€) and remote phones(12€).
I´d like to advise about the original Sony chargers: they used to put out too high voltage. The thing needs 6 and Sony gave ´em 9.
I found a Philips SBC 6608/00 charger that puts out exact 6volts and has the right plug. Just look for any 6vdc charger and adapt the plug.
When I had the 35 in the 90´s it used to get warm while plugged in- I never liked that. Now it stays nice and cool, even whilst running being plugged in.
Have a good time, I know I´m late to the party but had the urge to say something like "You lucky MoFo!"
Awesome job, glad you were able to bring your r55 back from the brink of button unresponsiveness lol. I find that a lot of what I buy broken to repair ends up just needing a simple clean to fix. It's always a good idea though to know how to do general cleaning and maintenance to keep our dated devices going for as long as possible.
I think it's interesting that this is almost the same idea that my analogue tape loving peeps have to live with - want to use the technology, you need to have some understanding of it. I think MD is probably the last of the digital music consumer tech before everything became solid state and you need to be able to do surface soldering in order to get any fixes happening.
That MD goes for more than the player! :D Good find!
I own the CD... maybe I should put it up on eBay. 😅
@@hirogarimusic If you love the album, and you love MD, you should sell the CD. ;)
Great stuff! :D Was happy to hear your genuine elation at getting it all working. Looks very fiddly to get into these little players!
I have massive hands and sausage fingers so I was absolutely overjoyed to just get the thing back together again without breaking any bits. 😅
Great channel this! Just a dude not really kowing what he's doing having a laugh and learning alone the way! Keep it up! Great content!
I do have some tips! First one is mute the audio when you're fast forwading, second is try to keep you're head out more.. it's probeply really hard when you're working but try to keep it out haha! Anyways without these adjustments the video is great!
Thanks for the kind comments.
@@hirogarimusic no problem! Keep up the great work!
Absolutely love it! Geat work, loved the video, and thanks for the shout out and the links. The REM disc on its own is worth more than $15 I would say.
That unit was in a mess. Great work on a thorough clean up. What surprised me was that the remote wouldn't work either. I wonder how the remote and the controller board are linked. Thanks again!
You’re welcome! Your videos have certainly been helpful.
I suspect (but don’t quote me) that the controller board was overriding the commands from the remote. When I was fiddling around trying to get it working without opening it up, it would actually occasionally respond to a ‘previous track’ button press but that was it.
@@hirogarimusic Thank you. Interesting info. I have a MZ-R70 that looks like it has a short somewhere, and using a compatible remote didn't help, so I concur with your theory that the controller board and remote are connected in some way. That could be handy when troubleshooting.
If I had to guess the front control buttons have a higher priority when polled by the dsp. So if something is wrong and the unit sends a stuck button command that ties up control then the dsp wont respond to any other front button nor the remote buttons. I ran across a similar yet different issue with a nintendo 3ds where most of the buttons stopped working, it turned out the screen protector was permanently pressing one corner of the touch screen which took priority over most of the other buttons making it look like the system was locked up and not responding to button presses. Removing the protector cleared up everything.
@@sjm4306 I suppose removing the button controller board ribbon cable and trying the remote only might help. Trouble is, I don't have a remote. Also, how much time and effort should a n00b like me risk trying to repair a a unit that I could replace from eBay for £50?
@@CBitsTech yeah just for a fun hobby don't pour more time and effort into a fix than entertainment you'd get out of it (otherwise your hobby turns into a side job lol). I started out fixing stuff just for fun and eventually started doing paid repairs for others and that just sucks 90% of the fun out of it.
Perfect
You got my like and new sus
Grettings from the facebook group 😄
Great vidieo will help me a lot also can you spray it with ISO and let it evaporate?? also how to clean the laser, is there a mini disc cleaner?
Thanks Dave
Good job mate
I have a unit that keeps trying to find the disk and never succeeds, it only marks 000 on the display, the engine scraping, it looks like it is trying to run ... Can just one cleaning solve it? Any tips?
I've had a similar issue. It starts, tries to run, and then shuts off.
Over time the belt dissolved.......😩
I have the same issue too! Would love to know how to fix this. Very intermediate and annoying!
@@TheHeed1969 These players are better repairable than iphones!
And yes,opening and cleaning would be the first step-alcohol on pads and get rid of all the dust - while doing so you watch out for all the movable parts and then looking on the plates if there’s something noticeable.
You might have a good chance to fix that on your own or with the help of some tutorials shown here on youtube for the specific models🤙
Tengo ese mismo mando (control) pero no enciende el display pero si funciona los botones. No se si solo funciona el display conectándolo al reproductor o hay que hacer algo más al control de mando
I'm sure you know by now, but that md album is worth a lot.
Can you give me a link to the ac adapter you use? My original one sadly broke :(
How about mini disc home recorder repairs? Can you?
Mine didn't have a power supply when I bought it can I use a universal power supply and select 6 volts without frying it?
You can but you need to pay careful attention to the polarity of the power supply. You’ve given me a great idea for another video - this is a particular issue with not only devices like MD players but also for synthesisers as well.
I'll give you a sub looking forward to the video I'm sure I'll learn something
This is a brilliant device and the only problem is the batteries that run our fast.
Hence why we always carried spares. ^_^
Do you have service manual ?
Minidisc is my no.1 favourite recording and music archiving format. But full sized minidisc recorders were a stupid idea and contributed to the failure of the format, minidisc was designed to be small simple as that, a full sized deck never made any sense to me, these sonys were 90% empty space inside, a real space waster for no good reason, this is why i LOVE my Onkyo FR-X7, sony machines suffered from two design faults, 1, their VFD screens faded like crap in a very short time due to being overdriven by the wrong resistor fitted to the VFD tube, and 2, their mechanisms were very poor, my onkyo is the best sounding minidisc machine ive ever heard.
I saw your reddit post
Nice
I have a minidisc recorder that reads discs, but won't play tracks. Anyone have any ideas?
Nice job bro! Bonus, that REM disc is likely worth +/-$100. At least that's what prerecorded MD's are going for on ebay lately. I was just looking tonight (no REM though).
Seriously considering it, but it is one of my ‘tester’ discs when I get a new unit.
Strange how they only owned 1 rem disk and no other normal blank ones.
They also included a consumer recorded MD with bass/drum/keys backing tracks for country-western.
The reason for trying to play a disc recorded on another machine is that it helps determine if the heads are properly aligned - sometimes you can record a disc and play it in the same machine, but it won’t play on other machines due to head alignment issues.
