Sony MHC-NX1 strip down and repair

- เผยแพร่เมื่อ 23 ส.ค. 2024
- I have never done a video like this before, so I thought it would be worth a try. I don't have a proper work shop, so had to improvise. The reason for doing this was that after 19 years of service, the belts that drive the tape decks had given up and perished. In order to remove the tape deck and access the belts a full strip down was required of the unit. I have tried my best to explain what's going on, but as I've never done a video like this before there's always going to be room for improvement. I hope you find it mildly entertaining and enjoy seeing the unit working as much as I do.

Re your comment on the volume control, I had a similar problem..... I took the case off, blew all the dust off the whole inside, now works fine !
Excellent, I still haven't opened mine up yet but I shall try that first!
Thank you very much, my HCD-GRX10AV/RX110AV seems to have the same deck, and it helped a lot to watch your video because it had some important hints how to handle the middle motor. I was able to repair the directly connected deck yay! But the one on the right side (from behind) there the up/down mechanism of the magnetic head seems to be stuck.
I'm not sure what lubricant to use on these, but perhaps some kind of lubrication may free the head off?
@@stephensrailways do you mean the casette audio head? I think I should maybe lubricate all the wheel axles, because meanwhile it seems that over time the audio gets slower and I am not sure if these two defects are maybe connected.
@@skybirdification I also have a sony rx110av and after having disassembled and reassembled the cassette deck to clean the stereo inside, when I play a cassette I always hear a whistle below (more present on tape b). you say that with some lubricant I solve the problem?
@@danielboss6835 I didn't try yet to lubricate anything, I still have the problem that the tape speed slows down but I was to lazy to take it apart again yet, as I mainly targeted on repairing the CD deck (the rubber was gone there too) and that is working fine now. But on my next holiday I will check the casette deck likely again.
@@skybirdification let me know if you will solve

Yes!!! I love it ❤
I have the Sony ex66 with ex77 speakers (on my channel) I absolutely love it! This ones very similar i think? The speakers look just like mine! Love the video
I've had mine boxed and stored away for about 10 years. When I stored it it had the same cassette deck problem. Worse than that the display was becoming unreadable.
Thanks for the tape deck video.
Anyone know of a display repair?
done my hifi and good as new, simple and i didnt even have to dismantle the tape deck front either. the belts went on a dream and was a tad fiddly at 1st
Dankeschön, mit deinem Video hast du mir geholfen. Grazie mille.
Could you make a video of how to replace display? I have the common problem of missing pixels.
Hi thanks for your video.I have exactly the same model of Sony deck as yours.The cd and cassette players were not working so I stripped the player and found every belts were perished. Your video of cd belts replacement is quite helpful thanks but for cassettes belt change it is somewhat confusing where the video has been fast forwarded.Saying this it is still helpful where video is on normal speed.Thanks
very intersting. I have same one but deck B belts are not same that yours. Belts mecanism is different
Hee.. my nx1 is not reacting to my remote!?
Any idea to fix that?
Great video, thanks! Not sure what happened, my amp works perfectly, but there's no power going to bottom unit, no lights. Does the power transfer from top to bottom over the system control ribbon cable, i replaced it recently but no change, any ideas?
Yes, the ribbon cable supplies power to the cassette/CD player. Maybe there's a dry joint where it plugs in that's come loose?
@@stephensrailways Weird my comment keeps disappearing. Anyway opened it up to find these (see link) burnt out. Bought it in the US and run with a step-down converter in UK, but there must have been a surge at some point. Don't see damage elsewhere, any chance that this little board took the brunt and unit is not totally fried? ie small board replaceable?

@user-kk4dh9vd7p the board looks OK, but it is hard to see exactly what the components were before they were fried
@@stephensrailways The little board sits on top of the black plastic chassis surrounding CD. Rethinking it, the power would have surged from the ribbon input all the way up there so it has probably damaged alot more whilst not really visible. Thanks anyway! Video here but not sure it will help much..

Hola 👋.....excelente tutorial. Tengo el el mismo equipo musical y tengo los mismos problema con las cintas de transmisión. Podrías indicarme donde conseguirlas? . Saludos desde santiago de chile. Tienes otro seguidor más. Gracias.
Holaaaa... Por fin un comentario de un chileno... Estoy en la misma que tu. Necesito recuperar este sistema de sonido. Lo amo desde chico. Pudiste comprar correas en alguna parte? Saludos
@@IgnacioClavijo hola estimado...aun no . Pero están disponibles en ebay y Amazon...se pueden Conseguir. Acá en Chile, imposible.
@@leonardopoblete1310 gracias por responder. Las he visto por Ebay pero por Amazon no. El tema es lo que te cobran por solo meter unas bandas elásticas jajaja
@@IgnacioClavijo en santiago puedes comprar las bandas siempre y cuándo tengas las muestras. No duran mucho. No son de muy buena calidad .Es un negocio ubicado en San Diego entre Matta y coquimbo. Buscaré el nombré exacto y la dirección si estas interesado.
@@leonardopoblete1310 acabo de encontrar una página muy buena que hacen envío no muy caro. Te puedo dar el link
Don't know if you are still collecting comments but I still have a problem with the auto changer. It changes ok when the trays are falling but not when they rise. The tray is a little low at the rear. Lifting with a finger before it times out engages the cd. Any thoughts?
I'm not sure on that one, unless it's to do with the belt that's hidden next to the laser, under the cd trays, that could be slipping. Very strange indeed!
Thank you for this video, it will help me a lot :) Could you tell the size of each belt as I'm outside the UK and the belt kit isn't available here

That's where I got mine from, and they do post to quite a lot of countries. I'll see if I can measure the old belts.

@@AzarMeu Thank you so much :)
I have sony hcd rxd8s i try to change the belts but the 2 coils is full down and get damaged
sir if you know each other naturally
all the rubbers are cut on a cassette player exactly like this one in the video
I press play on both decks, but without putting a cassette in, neither motor receives a command, is this logical from the switches you said are everywhere and see the presence or absence of the cassette?
should I buy some tapes and put them in to watch?
because all my cassettes are broken
That's correct, the deck won't play without a cassette being in
@@stephensrailways thanks sir
sir something more
as about as the unit amplifier
has a fan on the back place
Do you know if must working continously ? or is there someone thermistor and its working when its needed ?
sensor break ka option???
Hi, i have a question for you, a few days ago i noticed a sudden change in volume output, it got noticeably weaker, my guess is that it's amplifier's fault, do you have any tips how i could save this old friend of mine? There are no specialists in my area, probably gonna have to repair this bad boy myself and any help would be much appreciated.
Hi, apologies for the slow reply. I have not yet opened my amplifier yet, so unfortunately I'm not sure exactly what the problem could be. I could be a dodgy capacitor, a transistor or anything else for that mattter. If you do find out, please let me know, as it would be a shame to let such a good unit go!
Sorry, but the critical part is disassembly the front panel section and your video is too quick to understand. Is it possible to do it without disassembling the CD Dect? I saw it from the service manual but it's not so clear.
You have to take the CD deck out for the front to come off, but it does come out in one piece
hi nice video. can you plase send me the dimensions of bets? i have many dimension but i m not sure what dimension will be the best. Thanks
I'll see if I can find the measurements for you 😊
@
stephensrailways do you have a video where explain the same process as show it for to change belts for CD player?
Thanks and advance
I don't yet but can do, as these need renewing as well
@@stephensrailways I'm wait it!!!
@@stephensrailways Please do, I am looking for a tutorial on that as mine have all packed in. Nice video though, as my tape deck has had it!
@@nazcasteve video is coming tomorrow showing CD belt replacement
Video is coming tomorrow showing CD belt replacement
I have problems with both decks. The heads don't flip on auto reverse? Any ideas?
They should turn and spring back if you try and move them by hand with the power off. It might be worth trying this a couple of times to free them off, especially if its been a while since the deck was last used.
@@stephensrailways I give it a try. Thanks
Found one of these in the trash, display was totally dead, cd player and cassette player werent working, i couldnt find any replacement displays sooo... i just threw it back in the bin, i kinda regretted it
is possible open speker sony ss-nx1
I haven't tried, but if I find a way I'll let you know
