Repair a Sony SCD 777ES?


My 12 year old Sony SCD-777ES stopped working today. After the disc is inserted and the cover closes it makes some unhappy grinding and clanking noises as it attempts to spin the disk. It also switches automatically to SACD mode even with a redbook cd, but never starts to actually play the disc.

Can these old Sony's be repaired? It is a decent player and an excellent transport for my dac, I hate to just junk it! Any recommendations on the best way to get it repaired?

Picked up an SCD 777ES from a friend last year for 400, originally supposed to be 200 because he said it wasn't working. Tried it out, worked fine, hence the higher tag, with a 30 day return. Issue returned yesterday. Very slow read time and maybe a minute playing track one, never any deeper. Kept working it for day trying to "loosen" it up. Fortunately found this thread. Easily pulled the lid, then 5 screws holding a black cover revealing the plastic gears. Definitely seemed tight. Easily pulled the floppy washers and the 2 larger white gears. Rolled some fine sandpaper to open them up slightly. A little lube, all moved much smoother. Q tip and alcohol on lens while there. Up and running nicely in under an hour. Swapped in my Oppo 83SE for a listen while repairing, but glad to have the Sony back. Might try to track down those brass upgraded gears. Thanks for the good read and direction to look. 
Thanks! for the update - stevebraxtonI trust that your player is up and running now?Happy Listening!

Thanks for the info, I will attempt repair and I do have a copy of the service manual somewhere (I think).
stereo5, Your SCD777ES may be very repairable. The one I repaired required some work on Gear C in the transport assembly. It would not spin on the shaft which caused the read problem. I used a fine 3 mm round file to open up the bore hole. As I understand, the nylon gears over time become too tight and friction on the shaft causes problems. I also purchased a brass gear on eBay from seller igorek50 for future replacement. It tested fine after bit of filing on the bore hole.
Dgarretson post was very helpful on how to remove the transport assy for the diagnostic.

stevebraxtonno, I do not have any contact for Sony since they left Texas. Perhaps a Google search can reveal this information? I wonder if Bill Thalmann has the correct calibration equipment? He is awesome, offers excellent electronics service. I use a Pioneer Elite 59-AVi universal (CD/DVD/SACD) spinner.
I feel for you Elizabeth, my Sony SCD777ES is gathering dust as it will not read anything anymore.  It  last had the laser replaced 10 years ago.  Too bad Sony doesn't keep parts for their older units.  Now I use a McIntosh SACD player and a Esoteric SACD player.  I don't miss the agonizingly slow loading of the Sony.

jafant -
 Any contact info for Sony customer service in Michigan?  
Trying to find out if anyone has the Sony reference discs used to calibrate the laser assembly for SCD1 and SCD-777ES.

BTW, what player are you using for SACD?
jafant and all,
I am very happy to report that Bill Thalmann at MusicTechnology repaired my SCD-1 player. It plays great now.

Per Bill "disassembled, cleaned and repaired gear bearing surfaces to get friction levels back to normal."
Nice! alpha_gt

I like the Cary 306 as well. There are some that have problems w/ the Cary spinners, hopefully, the company will continue to offer parts/service for their cd/sacd players.
Been there and done that. Well, actually didn't do it. I had an old Sony SCD608ES, from the late 80's. Wow what a great sounding player! I kept it for 25 years! And it got to where it would not read discs. So, I contemplated having it repaired! I shopped around for parts, I found a laser assembly online for $800! Since they are so rare now. And little parts like the toothed sprockets and strange parts that operate the drawer. (Most likely the gears are stripped on your drawer, not the motor.) but just the parts were far more than I ever wanted to put into the darn thing. I could spend $800 on a Marantz player and have a nicer unit! So, the unit got trashed. I hated to see it go after such a long and healthy relationship, but once I got a new modern player, (Cary 306) I never missed it. 
Hi jafant,
 Yes.  I sent the SCD-1 to Music Technology in Virginia for diagnosis and repair several weeks ago.  Still waiting to hear back.

Thanks for asking.  Will update this post when I know more.

jafant-
I purchased the SCD-1 in 2003 from J&R Music World.
The build date is Sep 2001.
I'll keep Pyramid Audio in mind.  However, Texas is not close.  I am in the south eastern coast.
The local repair shop tech stated he will search for a replacement lens assembly.  Waiting to hear back.  In the meantime I cleaned and lubed the sled rails again.  Its working better today but still making a thumping noise.

stevebraxton-

you have enjoyed some milage out of your SCD-1. What year did you purchase it?  I thought of another avenue- if you are close to Texas, Pyramid Audio in Austin, may be of service as well.
Keep me posted.
Thanks jafant for encouragement on the SCD-1 repair!
To all on this thread who care to provide feedback...

I went to a local repair shop and described the symptoms.
Without looking at the unit, the technician concluded the problem is with the reader (lens assembly) and not likely the sled motor.
Do you agree?

The symptoms are listed below.


Dec 2016 problem with SACD & RBCD playback. Also, an occasional thumping noise inside CDP occurs. The noise can be heard across the room.

Intermittent error: No Disk
If play starts after loading a CD it will usually play all the way to the end.

If play does not start then eventually the "No Disk" error will occur.
I can hear the disk spinning during the load process.

When attempting to select a specific track, the track number shows on display but eventually, the "No Disk" error occurs.
Right On! stevebraxton-

Yes, there are parts still avail for the SCD-1. Lots of searching and researching these forums on A'gon and Audio Asylum will yield the intel you seek.  Rick Rubin and Henry Rollins still uses this CD/SACD player.
Highest praise there.  Keep us posted on your repair situation.

Happy Listening!
Good to see you- dgarretson

I liked the Esoteric for SACD playback only. DV-60 model.
I have not auditioned the true higher end spinners.  Happy Listening!
I still listen to CDs as well as vinyl. The SCD-1 is the best digital source I have. So I am very motivated to get it working again without issues. It would be a shame for a $3 motor to prevent enjoying this excellent CDP.

Hopefully, the sled motor can be replaced. There are 2 reputable electronic repair shops within 25 miles of where I live. The Sony recommended repair facility is in NY (United Radio Service). Did not get a good feeling about sending it there after I called.

I tried to remove the transport assembly to perform the maintenance recommended by dgarretson. Two corner screws came out easily with the correct screw driver, but I messed up the head on the other 2 screws with the wrong size screw driver and cannot get them to loosen.  Lesson learned. I am going to the local repair shop next week.



















Hi Jafant,  I moth-balled my heavily modified SCD-1 for an Esoteric K01X with Rubidium clock.  There is not a huge difference in performance, but only after modifying the Sony to the point that it became unrecognizable as such.
Are you guys still listening to this spinner?

The old Sony repair center in Laredo TX is now in Michigan.
There are other authorized Sony/Sony ES repair techs in other states as well.  Happy Listening!
Steve,  My files from the mid-2000s indicate that the sled motor is a Mabuchi RF-300CH 11400. 
dgarretson,
Thank you for the response. This was helpful.

Can you provide the name of the OEM manufacturer for the sled motor ?

"11. If you continue to have read problems, then replace the sled motor, which has been discontinued as a Sony part but is still available from OEM manufacturer."

@stevebraxton

Instead of tugging on it, try worrying it out with a rocking motion, or maybe working a jewelers screwdriver into the seam of the header. Don’t tug at the ribbon itself. Honestly it’s been a long time since I did this.

-- to dgarretson, czbbcl, or anyone who can answer...

Please describe the proper method to disconnect the ribbon harness on the Sony SCD-1 to remove the top cover. I tugged on the harness and it did not come loose, so I just rested the top cover on a box about the same size as the CDP and left the harness connected while doing some of the maintenance described by member dgarretson.


SCD-1/777ES Transport Maintenance

1. Tilt up top cover at rear of CDP and disconnect ribbon harness that secures top cover to Main Board at front of CDP. Remove cover and set aside.

Triller -

perhaps Dan Wright ( Wright Mods ) could be of service?
Happy New Year.
Thx Jfant. I talked to Sony Laredo (but prob not Adrian) prior to my post and they were not confident of having the parts. Round-trip shipping & ins would be on me since well out of warranty if they would be unable to repair - and the fellow I spoke with seemed both highly knowledgable and familiar w/the SCD-777ES.

I'm hoping to find an independent repair facility that will stay "on-task" until the unit is repaired. From what I understand, they are out there - just need to find one!
Triller-

check out Sony's reapir facility in Laredo TX.
Ask for Adrian.

Happy New Year!
Not sure if anyone is following this thread any longer but my 777ES is still mechanically-functional but appears to have an electronic component issue. After loading, the display will go blank and it just stops working. I have to recycle the "on-off" switch to recover the disc. It will not play, or will do so only for a few seconds. The display is intermittent.

My unit probably also needs the lubercation protocol detailed by Dgarretson but I've had no transport issues.

I've suffered a stroke and am unable to perform ANY repairs / servicing myself, so am looking for the recomendation of a name & contact number for someone who is competent to do so.

I'm hoping to keep this unit in service, its a great transport, an good sounding player and still draws incredulity when folks attempt to lift it!

Thanks for your input.

Triller
Swampwalker, sorry, I wrote that Sony mntc. procedure from personal experience and with input from Richard Kern, an early Sony modifier. I have no experience with Denon.
Dgarretson- do you know where I can find a similarly detailed maintenance procedure for the transport in a Denon 3910?
I did exactly what Dgarretson suggests when my scd-1 was giving me disc read issues and mine has worked great ever since....Still runs fine and this was a few years ago. Not sure yours is a sled drive issue or a bad motor/spindle problem.

Chuck
The verdict is in. I actually hate Sony and will never buy a product from them again for reasons already stated +. Like Bell, their customer service is "0". Besides, lots of companies with good reputations make products equally as good or better. Pick yourself up a used Oppo 83SE. It'll spank Sony's flagship model for about $400.00.
Remove the top cover, the transport billet section, and clean and relube. This solves the problem 80% of the time:

SCD-1/777ES Transport Maintenance

1. Tilt up top cover at rear of CDP and disconnect ribbon harness that secures top cover to Main Board at front of CDP. Remove cover and set aside.

2. Remove ground wire to transport billet & screws securing transport at corner stand-ups. Lift transport with attached RF PCB straight out, while carefully pulling out two wide ribbon cables that secure transport assy at rear edge of Main Board.

3. Remove transport assy to grounded anti-static mat, being careful at all times not to touch laser lenses or to lean laser pick-up against any surfaces.

4. Remove retaining washers from round gears, taking care that they don't fly away. Remove round gears. Remove Sled Motor together with its bracket/PCB. Leave small plastic drive gear attached at end of sled motor shaft. Remove cast CD drive spindle motor assy. Remove cover plate from end of CD spindle motor assy, exposing sapphire bearing, brass bearing cup, and spindle motor coils.

5. Use swab and solvent to clean grease & dirt off all round & straight gears of transport assy & jewel bearing and bearing cup of CD spindle motor. Desolder and remove sled motor from its PCB, noting motor polarity before dissembling. (Motor runs backward if reassembled with incorrect polarity.)

6. Spray Deoxit into sled motor housing through holes exposed after desoldering sled motor from bracket/PCB. Apply opposing polarities of a 12V battery to motor poles, so as to spin sled motor in opposite directions and burnish brushes for about 30 seconds. Resolder sled motor to PCB. Reassemble sled motor assy to transport.

7. Confirm that there is almost no lateral play between CD spindle and its cast housing. Replace spindle motor assy if there is excessive lateral play or if spinning operation has become noisy. Put a drop or two of mineral or telfon oil into the collar bearings at each end of the spindle shaft housing. Remove any dried brown grease from jewel bearing cup and motor coil areas & replace with a small dab of white lithium grease or automotive moly grease. Reassemble CD spindle motor and reattach assembly to transport.

8. Apply white lithium grease to metal spindles of round gears. Put on round gears and confirm that they rotate smoothly. If they're tight, then you may have found the source of SACD read problems. Proceed with caution, but you may need to slightly enlarge the bore diameter of the plastic gear with a drill bit one size up from the stock bore. The drill bit must be inserted and turned by hand only.

9. Reassemble and lubricate all plastic round & straight gears sparingly with white lithium grease. Put a drop of mineral or teflon oil on each metal sled rail. Run the reassembled sled back and forth a few times by hand to make sure it runs smoothly and to spin off excess grease. Take care not to get grease on the tiny electric eye.

10. Reassemble transport to CDP, taking care not to peel back metal traces along edge of two ribbons as they seat to the Main Board headers. If any metal traces peel back, then retrim the ribbon using paper scissors or replace the ribbon.

11. If you continue to have read problems, then replace the sled motor, which has been discontinued as a Sony part but is still available from OEM manufacturer.
Sony repairs are a waste of money. Buy a Sony refurb, direct from SonyStyle, is a better deal, at least you will have a 90 warranty. Typically if it is bad it will prove to be so withing a few days of start up, and Sony will come get it, for free, refunding all your money. I've purchased four Sony 595's, mostly for $60 a piece with free shipping. I use two, and have the others as backup and for resale. These are five discs, SACD players and they sound and work well. Sounds almost as good as my Sony 777es and 5400. I have purchased other Sony refurb cd units and have have always been pleased.
Sony Repair is legendary for their bad service. And Sony Suctomer Service is equally as bad. After dealing - for 4 exasperating months!! - with Sony on the repair of a very expensive monitor, I sold the damn thing and vowed to NEVER buy another Sony product again.

So far, I've kept my vow...

Flip a coin. Those are your chances of a satisfactory service trip to Sony in Laredo, Texas.
I sent them my 777 in it's original box.
The first thing they do is recycle your box. Then they fix the player on a flat rate schedule.
My player came back to Phoenix in a single box, with the heavy CD puck in a plastic bag, duct taped to the top of the player, with one piece of duct tape. This allowed the puck to slap against the surface of the player, marring it.
And, most importantly, the player still wouldn't play CDs or SACDs.
I had to wait for a Sony tech to call me (in a 2 day window) before I could get an RA # from Sony.
The biggest insult came next. The tech said every piece is thoroughly tested before it is shipped. I actually had to return the player with (1 each) non playing CD & SACD.
He said it was probably my discs. Yeah, right!
The player came back, this time with a new transport. Since I had already paid $220.00, the 2nd repair was "free".
Sony had my player tied up for over a month. When I questioned why my original box disappeared, they said this point is clearly stated in their FAQ section.
I immediately sold the player, and sold my XA7ES a year or 2 later. I'll never buy another Sony player.
