How I fixed the Sony Mini HiFi CD player grinding noise and a look inside the system

Since Sony's service centre said they won't fix stereos that are over 10 years old, I decided to take the HiFi system apart and disconnect the CD changer since I don't need it, and poof! the noise is gone and the stereo plays back songs on the AUX input without any issues.
By the way:
1. This system is NOT for sale.
2. I do not repair HiFi systems

I own an Sony MHC 881 system and CD changer still works after nearly 25 years. My grandpa bought a system from 2005 and after two years both CD and tape player were dead... They really cared about quality in 80s and 90s.

[@4andronicus]

Why does this sound better than any stereo i have heard in years despite the fact it is through my headphones on my mobile? None of this makes sense and yet.. there it is. That sounds beautiful.

[@goodnightmoon]

audio stuff from 80s and 90s sounds more incredible that modern shit ones even if it's a sony or other big audio companies

[@bergi112]

Thank you, your video gave me confidence to open my device and check the belt- the CD tray wouldn't open Turned out the CD tray belt just slipped over, I doubled it since it is worn out and put it back on- perfect again

[@salmanshahzad8562]

Around four days back, I bought a Sony RXD10AV (which is 98% similar model) except that it does not play VCD but comes with other packed features such as DVD 5.1ch input and Dolby ProLogic Surround. It's also a very lightly used model with some scuffs. The tape deck was failing on me but I managed to fix the belts on one of the tape decks. I was lucky to get that...… THE SOUND IS AWESOME...BASS IS BLASTING...

[@BrucifyMe]

It's incredible to see the level of quality inside the older shelf stereo models. Huge transformers and heatsinks that you'd typically only see in the real deal home theater receivers. It gives you a hint as to the power, quality, and amplification abilities of these things. I'd say the MHCEC909IP model (the blue 540w RMS model) is the last high quality model from sony, as far as components go. The successor to that model, the black 700w "MHCECL99BT" and its non-bluetooth counterpart, switched to class d amps and if you take them apart, they use very small power supplies, caps, heatsinks, you name it. They weigh less than a game console. It's obvious Sony saw the decline of interest and stopped trying around 2013/14.

[@albertpintor3522]

I used to have a jvc hxd77 and it had a small heatsink with ic amp and small transformers

[@luciabreccia1901]

THANK YOU SO MUCH! I had this exact problem and thanks to you I don't anymore. I don't really care about the CD function so I just disconnected the cables from the motherboard and got it to work again. You saved me from throwing it away.

[@laurajeffers7804]

Thank you! Although I replaced the broken belt with a hair tie of all things (exact size match!) it didn't fix the buzzing completely so I simply unhooked the power to the CD changer as you instructed. There must be another broken belt deep within but I'm not using the CD feature anyway.

[@TechGuyCharlie]

That is awesome! mine is still broken lol, sadly discarded all my cassette collection a while ago! I've hooked up a bluetooth streaming device, and it works great with my phone.

[@GreyBlackD]

I just bought an used VX8 yesterday. The sound is amazingly good. There is the same problem though, the CD belt and cassette belt are torn. However I still own the GR8000 which is a beast.

[@clauschristiansen3267]

Thank you for the video, it helped me to fix my CD player. I used two rubber bands, works perfectly.

[@ugh.idontwanna]

The "bodge wires" are jumpers. It's just a simple way to use both sides of a single layer PCB. This technique is still used on multi-layer PCBs on more modern electronics, though they tend to use surface mounted 0 ohm resistors (I assume it's easier for the assembly robots)

[@abdelkaderelbachir9523]

[@Euge79]

Excellent video. Just solved the whining noise in my Sony Rxd5 of the CD changer continually spinning even when listening to tuner/radio. When I opened it up the CD changer belts were still functioning and the disc changer keeps spinning. I disabled the motor as shown, no more noise. We only use it for the radio. I did notice the tape deck belts were lying in bits. Thx for posting you help me alot. Interested in the Bluetooth audio receiver option you mention.

[@TechGuyCharlie]

Thank you!! I still have this stereo and have been thinking of getting the CD changer fixed, but don't see any point in doing so lol. I have a tutorial on how to install and set up a Bluetooth audio receiver, I'll link it here: kzbin.info/www/bejne/gWOll5hjr9aXodU

[@feco6891]

I have a Sony HCD-R550 , aprox. is the same system , the speakers are just3way but the woofer and demsions is the same ,is also from '99 and sounds very very clean and loud , you are lucky becouse you get theese speakers brand new 👍👍👍👍👍👍👍👍

[@TechGuyCharlie]

When I bought this, I was afraid the woofer foam might have rotted out since I was told the box has never been opened and it was sitting in a home which was locked for almost 5 years, but thankfully everything was perfect. Yup, these speakers are really good, sounds better than today's Sony's tower HiFi stereos. 😊

[@khetebhaloporomanno]

Excellent video! I have a MHC-RV6 bought in 2003 which now have the same fate with the VCD changer module. Produces the same grinning sound on power up. Will use your trick to depower the CD changer. Thanks a lot. 👍

[@TechGuyCharlie]

RV6 is a great system! Let me know if you were able to cut the power to the VCD player.

[@egenc94]

Quick note: If you have the same issue and want to unplug that 2 plugs (10:38), move them upward. Same axis as the cables, do not try to move them away from the board (perpendicular to the circuitboard). They had rails inside, it was hard to judge the direction needed to unplug without damaging the circuit. It worked in my case

The noise kept coming and when ever I want to listen to music the CD tray use to come outside with noises too. I would just like to ask you how to disable power to the CD tray and how to install bluetooth in the system. Would really appreciate the help bro. Thanks a million ton bro

[@ttown55]

I have same unit. I replaced a broken belt with a rubber band. Buy a bag of different sized rubber bands. Used a small one and works perfectly.

[@TechGuyCharlie]

I gave mine to our local service guy, replaced belts for CD and cassette, both are working now :D although I have no use for both CD and cassette lol, still it's nice to have a fully functioning unit.

[@owenadrian8905]

what kind of rubber band did you buy?

[@ttown55]

Owen Adrian it was just a regular rubber band. I bought them at a dollar store or something equivalent. They came in a bag with a;pros 100 different sized rubber bands. Not a big rubber band. Not a small rubber band. Just medium sized. Plus , I left the side of the stereo off after I replaced the band. I was surprised how hot it get inside there, so I decided to just leave it off. I really like the stereo and was going to throw it away, but decided to give a rubber band a try.

[@owenadrian8905]

[@richardspencer4901]

I have the HCD RX7C which is virtually identical and was making the exact same noise. Ordered a pack of different size belts from Amazon for very little money and fixed the two belts for the cd changer, took about 5 mins to do and its now fixed. Now I need to work out how to do the cassette player cos after approx 25 years all the belts were like liquorice.

[@TechGuyCharlie]

Thats awesome! a bit of isopropyl alcohol will do wonders removing the gooey old rubber belts.

[@richardspencer4901]

I need to take the front panel off using the service manual, it's too fiddly to do it in situ

[@TechGuyCharlie]

That is one of the reasons why I didn't bother fixing mine, I was ready to pay Sony for it, but they just refused to fix it, said they don't have spare parts for 10+ year old products.

[@ratnadeepdhar4816]

[@Shamsithaca]

They dont make products as good anymore...i think the last was 1997, 1998...1997 being the time when SONY had the most RnD, money and sales...everything from 1988 to 1998 were top notch. So a decade of incredible stuff.

[@juanmartin2267]

Thanks bro, I have the same problem, Now I only buy the belts

[@chrisradical2046]

Great video dude. Might as well order the belts and fix it. It's a shame for a good machine (no matter what that is) to work half way. Specially if the fix is easy. This year, since we are locked in the house anyway,I went ahead and fixed all the stereos and boomboxes that I had since the 90's. I also don't use cassette or cd anymore and hacked some of them to have bluetooth. But it's good to know that they still work and are in great condition after 3 decades of use. They don't make 'em like that anymore.

[@richardcrook2112]

Video was really relaxing. That has better bass than my speakers, maybe I should get one.

Thanks Richard, the audio quality is much better in real life since the camera mic is not able to capture the full range.

I had similar issue, CD making noise on both of my identical stereo's (GRX35) in the last 12 months or so. I never used the CD, so its almost certain, that it was a "feature" they programmed. CD goes bad after 10yrs and annoy the user, so we would buy another one.... I did the same thing, disconnecting it, so they could not trick me either ;) Thats just my thinking though.. Awesome product BTW the sound is just amaizing considering its size and age.

Hi tech guy Charlie, First of all a big thanks for making a video of your repair attempt. It helped me gain courage to open and fix my MHC-G880 (bought in 1999 by parents) which had pretty much similar issues as your system when I turned it on almost after 10 years. Now when I play it I am reminded of what I was missing .. pure awesome sound with deep bass . Couple of thoughts. I could not unplug the CD unit power cables on the main board as you did. Was not coming out easily. Instead I removed the plugs on the other end on the CD unit board. Just in case someone faces same issue. The bluetooth unit. I bought the same tp link that you have but realized it is v4.1 .. no deal breaker as the sound is awesome and range is good. However, I think a bluetooth v5 might be even better as all the new phones and devices are v5. Will that improve sould further- I don't know. Range and stability - definitely yes. Lastly, I am contemplating fixing the CD unit belt but not really feeling pushed. I have few old CDs so again nothing much to gain and am happy with the way system works now. What about you? Did you fix the CD unit? Thanks again dude.. :)

Mine is a MHC-DX3 and everything works fine but when I put caseetes in to play or record which was honestly the main reason I bought it, it randomly switches back and forth on the rewind and fast forward and makes super loud clunking noises for a while and then goes quiet and does nothing. I can't figure out what the issue is or how to fix it. It's the only issue I have with it. I just really want to record and play casettes, I don't think I'm able to fix it myself so I'm just hoping some repair shop nearby is willing to fix it, assuming they had the parts which they usually make you buy yourself if it is uncommon and overcharge...
