  1. Wow, bluecrab, somebody answered this. I thought no body had any opinion, or it was a stupid question. I have not begun the installation yet, but I have settled on the 800rec. That's because of what wires it has and what harnesses I have here at home. I have purchased an aux in system to interface with my indash 6 cd changer. I doubt that I will ever do much recording, or even editing. But that's an option. Thank you for your opinion on which one. 2many

  3. I am getting some light in this crazy tunnel. Several more attempts to get proper functionality were fruitless. Bypassing the power strips and going right off the power conditioner did not bring back the three MD's currently installed. Funny though, one previous unit which had entered the crazy zone previously, continues to work outboard of my whole stack of stuff. Almost seemed as if putting an MD in place for operation was the cause of malfunction. But no... At the time my electrical service was upgraded to a 200 amp service, I also had an 80 amp service drawn to, and installed at the other end of the house, thus supplying service to audio equipment. I got to thinking about checking or replacing the breakers. I reset the breaker supplying power to the brownroom in the 80 amp panel, as well reset the breaker to the 80 amp sub panel at the main. The decks all function as normal now. What I do not know is which one was the culprit or what was wrong with it. Supplying power, yet oddly not appropriate power. The MD decks are on std-by 24/7 by sony default. Might be why they were affected because of that.But too, I remember when the power went out those four times, coming back on almost immediately, but not with out a seemingly crackle or a "short" as it was doing so. I mean maybe a corroded surface on the contacts of the breaker that was not letting GFIC or polarity be proper? I do know that the voltage was not the issue as you can see in the following photos I will load. Photos taken prior to breaker reset. I don't know what was wrong. I just need to decide now how I want the final hook-back-up to be. IE, MD's on a separate surge protector?
  4. Right, the one thing I have not done as I pass through the auto check logs is clear the history. I merely examine the logs and move on. Careful not to make any alterations concerning operation. These decks all have been trouble free but for 940 belt issues and the logs show the code ten which I think was related to that. More switch outs and trial runs will take place today.
  5. D551E335-873D-4C36-88A0-1571AB6A2698.MOV If your deck is left on with no disc, this display begins after a minute or two of idle time. If the power shuts off, then is restored, you are going to find your decks have turned on.
  6. OK, end of the day at the end of my wits! This all does not make sense. Ya don't just have 3 MD's go down on the same day. They has to be a factor. Theorize with me if you will... I have spent much of the day MD related. I have been through the auto check. (slightly different between 930 and 940) basically I was careful to avoid altering any values. It seemed that doing so cured my problem, but wait, I take the decks back to the editing suite and they are doing again with out consistency and with out any one unit being the exact same difficulty in operation. The 930 seemed cured partly, but not trustworthy to execute a function upon pushing a button. Discs refusing to eject after 30 pushes on the keyboard or unit, then suddenly popping out. Jumping to track 14 and playing less than ten seconds before returning to the start of that track. Weird stuff! Trying to record every chance they get. So, I reserved that I need service. I got two units off the shelf, one out of the bedroom rig and replaced all three. Tested first. Like new 930, known working 930 and a 940 I put a belt in recently. working units. I install them all and rehook everything. They are all messing up. Same kind of malfunctions. It's like some fairy sprinkled some anti MD dust in that room! I try the auto check trick in that room and to no avail. So now I am in the computer room where I did the initial auto checks and I go through the process again. 940 A, I write down the last ten codes. 940 B the same, write down the error codes and back out of the auto check. Deck A has no disc in it and when test mode ends the deck initializes...That is a good sign I have witnessed before! stick a disc in and all is normal! Deck Bhas a disc stuck in it so when the check was over it just went into the on position showing the name and time as usual. And the disc plays, all functions are proper. With that being done, with three new working units being installed then failing too, Gotta be fairy dust in the room... I have a ton of components in there for editing and for band practice and recording. I've had a lisenced electritian bring in power for that room. The rack mount stuff plugs to rack mount power conditioners. But the stereo stuff generally runs off of power strips. I am not so good with a multimeter and have not checked that. I did try auto check using an extension cord coming from a dedicated known good circuit elsewhere with no magic result. My theory as we stand here tonight is... THE POWER STRIPS They must be causing this some how. They are inexpensive power strips. My observations remember was that when the power came back on, and I went to check, the three decks did not need to be shut off. They were off. they should be on after the power is restored. I have had them on uknowingly for days after an outing. Anyway, having the power flicker off, come back on for a minute, shut back off again four times might be the factor. Damaged the power strips? The logic in the MD's must be the only component that is suseptible to MD fairy dust. I am sitting next to two 940 decks that work normal, but two hours ago were malfunctioning. The 920 in the garage seems to work fine. The two 930's in the bedroom work fine, (till I took one to the ...It's called the brownroom...) Where all this malfunction is going on. So, power outage, cheap power strips. These are the kind with an on/off switch on one end. I am thinking of going out for some higher quality options there. In the meantime, here are the error codes from the two 940's sitting next to me that seem like nothing ever happened. What does it all mean? Deck A code 1-50 code 2-10 code 3-20 code 4-50 code 5-10 code 6-20 code 7-50 code 8-10 code 9-51 Deck B code 1-50 code 2-10 code 3-20 code 4-50 code 5-10 code 6-20 code 7-50 code 8-10 code 9-20 Nearly identical, though 930's are reading slightly differently. Details of Error 10 Loading error 20 Time out. The beginning of PTOC cannot be read 50 Address cannot be read although access processing is not in progress 51 Runaway due to focus NG Thanks for listening, what do you think? 2many
  7. “Service mode”... how do you initiate a service mode? Isn't there a self diagnostic that can give an error code?
  8. Home decks button's failure to respond. Really odd symptoms and seems that three decks failed at the same time. What I am perceiving is that there is a logic problem somewhere and this might be caused by a power failure the week before. So my explanation could be a bit long winded, yet I really need some help. Or pointers in the right direction. Like how to reset them or do the self diagnostics. Took a picture of my work station area. I have two mds 940's and one 930 in the stack. I am utilizing most all of the audio hook ups with each one to interface with the rest of the gear. Power supply is reliable but not governed by any kind of serge protector. The decks themselves are plugged into power strips along with other gear. The three units in this location seem to be the only units affected by this "bug" I just came up with. I have not turned on any mini disc here for a few weeks and it was five days ago, we had a power outage. That is the only thing I can think of that may coincide. I am fully aware how these things operate and what happens when the power goes out. After power is restored, the units turn on. Typically you are going to see the readout, no disc. Then after a preset time each unit will go into a scrolling sony MD sort of an advertisement. They will stay that way until you shut them off again. This power outage was peculiar in that the power went off four times consecutively for short periods. the fifth time it was out until the next morning. I was working on the computer in the other end of the house. I have not used the MD's until today and now I am experiencing some malfunctions. It seems as if the buttons on the front of these are unresponsive. The two knobs do work when turning them, but the push button does not activate anything. Eject, power, time, display... all of them fail. If you power off with the power strip, then on again and there is a disc inside it will begin to record on it. You can not shut it off. No buttons work. My 930 is the main utility and is controlled with a keyboard or the buttons on the face. I thought it just gave up the ghost, but when trying to operate the 940's, I found they had similar problems of failure and illogical operation too. On the 930, I tried titling and it was very erratic. Out of control when it does input something, but generally unresponsive. Adding letters on it's own, mostly "s". If you repeatedly press eject, or other letters, I have finally had that work. (930 only) So this time when the power went off, these three decks were not automatically on when the power was restored. Due to the nature of three acting strange at the same time, I suspect the power some how did this. However, there are two other 930's in a different room and a 920 in the garage that have not suffered any oddities. There are E-12's that show no signs. It is just these three in that room. Sorry for the long story, but I hope some one has a clue. Ever heard of this type of malfunction? These have been bullet proof other than this odd failure. No other items in this location show ill effects, (tascam pro CD recorder, yamaha hard disc cd recorder) I did not try the sony cassette), just the MD's in this station. HELP! 2many
  9. I am leaning towards the C800REC. Has anybody ever owned/used one of these
  10. Hello, I thought I would throw this out for discussion. I have 3 in dash units that I must choose one of, to put in my truck. C6500X C8500X C800REC So, I have to choose which one I am going to install. The installation is not as a head unit, but merely an auxiliary in on the 06 GMC Sierra's original 6 CD changer. I will be powering up the MD separate from the ignition and will be stubbing out some speaker jacks for when I want to set up auxiliary speakers on site somewhere. (an option) The main function is to play MD's through the original system and speakers while driving. (I am sick of my CD's skipping) Now for the choice; I am somewhat confused as it has been years since I pulled the unit out of my dash of a 77 Datsun. What I mean is that I can not remember for sure which one I had been using. The other two, I have never used. Governing my decisions partly is the wiring harnesses that came with them/are available. I just took some pictures and will post later today. But my foggy memory tells me that I used to run the 6500. Noticeable fingernail scratches on face plate. Yet the plugs on the end of the harness do not look familiar. Wide block into the deck and two separate female connectors of which I do not have the male for. My foggy memory tells me I bought the C8500X because it was an upgrade. (50 watts) And yet, I do not think I ever used it. Again, wide block emanating from the deck and with a female connector out of the pig tail that I do not recognize, nor have a male for. And I do not remember the female subwoffer output wires either. The C800REC face plate looks to be that this unit was never used. I have it in the original box with papers and manual. At the deck, the pig tail plugs into a narrower block and the other end of the witres have never been stripped off. It is like this thing has never been installed! A pro for the rec is that I can divide and name ect when I am away from home. Not a big deal as I could do that with one of my portables too. To sum it up, the two different pigtails on the 6500x and the 8500x would be interchangeable, But either way, I'd have to cut into the wires. The 800rec is more ready to go, less complicated, has no female plug on that end of the harness...ect. Later I will post pictures of these. Regardless, I am going to have to hook whichever up and check for proper operation. Just thought I would throw this out for discussion. Interested in pro's and con's. Like I say, I used to have one installed in my car and liked it a lot. No problems. And my other truck had the earlier 7900 in it. It is still running with out failure, so I feel pretty good about that after all these years!
  11. Yep, just to load and unload. BUT... my belts lasted a bit over 15 years before they got a little slack. Rubber bands turn to goo in about five years.
  12. Remove the four screws holding the drive down and just raise the front of the drive up over the faceplate. Tweezers will pull the old belt off and install a new one right throught the front md slot. No need for other disassembly. rubber bands are not belts. Yes, they work. Interested in how long they would last.
  13. I have fonally got around to servicing the two jb940’s in my work station’s stack. Been putting it off due to the complexity of access to it all. I can say I am a pro-installer of belts now after a total of 6 units. And with proper belts on hand it is a five or ten minute job. However, changing the four belts on a sony tc-we835s turned out to be an extreme pain. Difficult to find information, tips and tricks. In the end I am successful there too. I am currently on my way back together after a total wipe down of dust, re-vamping of all wires and a deoxit spay of noisy pots on the technics sa-700. That tape deck.... whew. Give me minidisc all day!
  14. Wow! The rubber feet would be handy if you were not rack mounting it. Is that one the pro?
  15. I have 3 e-12’s and one e-10 they initialize like yours IF left unplugged for an extended period. None say pro after the model # so you must have an early or a late one. A special one?
  16. Now we are getting somewhere? Out of hundreds of discs I have maybe two that seem to hate being inserted. They fail to read. That’s it, go to another. With those above, at a glance, I notice nothing wrong. What are we looking for?
  17. It is a very nice format and loved by many! As well, many units can be had for a song and a dance if you keep an eye out. Get a sony deck, or a tascam or get a portable for mobile use away from home. then you can test back and forth. Sorry your $10 unit isnt working.
  18. 422702501 one more thing. All you need to do is remove the four screws holding the drive down. Then insert the new belt on the pulleys through the front of the drive. It is that simple.
  19. 422702501 This has been a very long journey. Trying to get a stupid little “rubber band”. One of the biggest break throughs was the posting on this thread what the actual sony part number is. 4-227-025-01 I swam through a sea of wasted purchases from sellers around the world with generic pictures of belts regardless if it was “the one” for the mds e12 or jb940. I waited for postage to arrive only to be disappointed at big-ole thick belts of varying diameter. I made calls, I drove to small repair shops, I was told by electronic repair facilities md decks are not worth the money to repair them. mdm-7 drives use this little belt to load. When the disc does not load properly you get a read error or a c-13. The disc will not eject in some cases, or it spits it back out in others. Between the 22 pro + consumer decks, car decks and portables I own. Along with the hundreds upon hundreds of discs I have recorded, I am not about to give up because they say they are not worth fixing. Today my six pack of belts arrived from; www.partsdistribution.com in denver colorado. They are genuine sony belts repackaged for uniformity. They are the real thing and they work like there was never a loading problem in the first place. Having the real part number opened up a wider range of possabilities. Amazon listes them, but are out of stock. Walmart lists them but are out of stock. Electronic parts distributers list them as discontinued. Using google search, armed with a real part number, I found partsditribution.com I needed 6, I bought 6. Now I can begin the easier task of extracting the e-12’s currently running on true rubber bands bought from the $ store. Then the more difficult job of extracting two 940’s from my work station. And while I am at it, a belt replacement pack goes the tc-we835 cassette with eject failure. my hair is already grey, so my face turned blue instead. We can call this saga over. But the number 422702501 should be a header at the top of everyone’s post just to make sure no one else goes through hell and back for rubber bands. pictures... An aray of used and new belts. My work station with the 940’s. A four belt pack for the cassette. Other than to save money, why would sony change from the robust gear driven mechanism of the 930 to a tiny little belt? I don’t know.
  20. That is odd. Seems to be traking continuously along. Never heard one do that before. Do you have another disc to try? Does it do that with others?
  21. Yes, thanks. I ask myself why the 17mm belts do not work for me when they are fine for others. I have a completely new line on proper sony stock. Shipping from denver colorado. I will continue to show the results as time goes on. I bought out their current stock of 7 belts. Provides me with one extra. Fingers crossed. I was shown a picture of the item I am purchasing. Looks right!
  22. Just found this info on how to measure a belt from the Wagneronline.com site. They show a host of belts in the 1.4mm square thickness. HOW TO MEASURE PLEASE READ ME! Suit Cassette, Portable, Dictation machines, Personal Audio, 3in1, Turntable, CD, and maybe some Reel to Reel. For Video it is advised that you use only original parts, please enquire. Please take care in measuring and selecting the correct size of belt. Extract and squeeze the belt together, measure its length then double it to give you the belts total length. Note: Do Not Order using the Length value. From the tables listed, read off the diameter. This is the value used in our codes. Choose the next size down if the belt is stretched. The thickness is a measure of the cross-section of the belt. If the belt is missing or damaged beyond recovery then you could duplicate the belt by running a piece of string around the mech' and use its length as a general guide. Please take advantage of our discount structure. The belts are available individually but are 10% cheaper if bought in bag quantities of ten (No mixed values). WHEN ORDERING QUOTE THE DIAMETER & THICKNESS ONLY They range from; Image Order Code LENGTH More Info Cost inc GST Cart 10X1.4 31 mm Details $ 3.00 -+ Add To Cart 12X1.4 38 mm Details $ 3.00 -+ Add To Cart 13X1.4 41 mm Details $ 3.00 -+ Add To Cart 15X1.4 47 mm Details $ 3.00 -+ Add To Cart 17X1.4 54 mm Details $ 3.00 -+ Add To Cart 19X1.4 60 mm Details $ 3.65 -+ Add To Cart 22X1.4 69 mm Details $ 3.65 -+ Add To Cart 25X1.4 79 mm Details $ 3.65 -+ Add To Cart 27X1.4 84 mm Details $ 3.65 -+ Add To Cart 30X1.45 94 mm Details $ 3.95 -+ Add To Cart 31X1.4 97 mm Details $ 3.65 -+ Add To Cart 33X1.4 103 mm Details $ 3.65 -+ Add To Cart 35X1.4 110 mm Details $ 3.85 -+ Add To Cart 37X1.4 116 mm Details $ 3.85
  23. Just about to pull what little hair I have left OUT! At least we seem to have a proper part number from sony's files now... 4-227-025-01 I surely would like to have proper belt quality going in to my 940's as they are not easily extracted from my work station. As for the e12's, it isn't as much of a problem to remove the deck.(currently using rubber bands) The belt 4-227-025-01 pdf above is a fantastic resource. In a few hours, when they open, I will try encompass electronics in las vegas nevada. They list the item. (at a better price than most) I do still have two new belts on the way, (currently in new york and in transit) from "web-spare-parts". We shall see what they think the right belt is for a mds e-12. Many other sources show that belt (4-227-025-01) as out of stock or no longer available. I would think that belts should be found for just about anything and going in incremental sizes so that you can retrofit just about anything needing a belt. Yet for some one like me, it has been difficult to find a supplier or to properly identify what I need. I found a Brazilian supplier, but would rather avoid any more international purchases or further guessing if they indeed know what the right belt is... A pair of belts from rubber king. At least in the picture they provide, the belts look more like the original sony! But why a pair of belts? Another fact that throws me for a loop is the fact that some suppliers state something to the effect; "This deck takes two belts, make sure you got the right one". There is only one belt in a 940 or e12....right?
  24. Ha, that's funny. Thank you for your deciphering! In the meantime, I did a google search for sony loading belts. They can be had on store sites such as walmart, (out of stock) amazon (6 available) Problem is, they are $13.99 plus $4.63 shipping!!! They are being supplied by a place called "buy parts here". When you call buy parts here you get some variant of global sales... fishy smelling. I already bought wrong belts from global. Also found them at "overstock" (two left) again 13.99 each. Neither give any specs. I would like to have the proper belts in my decks. But...At this point, I am just about to stick with rubber bands unless I can find a proper belt at a decent price.
