kris01 Posted December 27, 2017 Report Share Posted December 27, 2017 Hi I bought not working JA555ES as a parts donor for JA555ES and JA333ES. It even didn't power up. Broken shaft of AMS encoder. Inside I noiticed some flat wires unpluged. Missing loading belt and lever (lock) assy X-4949-790-1 (not available anymore). But I gave it a try. After pluging all wires it powers up and display shines as new one. I managed to create lever lock. First I wanted to print it 3D but with no luck so I did it manually and it works. Next I tried to repair broken encoder. I bought one encoder from Alps and second from Bourns but the old was from Panasonic ;-( . Anyway I put Bourns encoder because it has longer shaft and works smooth and can stand more cycles. The only drawback is that it rotates in different direction than original but does its job. Maybe anyone knows what Pansonic encoder should I get or have spare one. After assembling it turned out that this MDS-JA555ES has played only for 131 hours and recorded for 64 hours so seems pretty new one.

kris01 Posted December 28, 2017 Author Report Share Posted December 28, 2017 but still I have no loading tray for JA333ES. Quote Link to comment Share on other sites More sharing options...
PhilippeC Posted December 28, 2017 Report Share Posted December 28, 2017 But a brand new JA555ES. I ask to a friend on the laserdiscplaza.fr forum if he has a deck for you. Quote Link to comment Share on other sites More sharing options...
kris01 Posted December 28, 2017 Author Report Share Posted December 28, 2017 Maybe he has only loading tray . Another MDS could be too much, I already have 3 x JA555ES and 2 x JA333ES and besides couple other different types . Quote Link to comment Share on other sites More sharing options...

kris01 Posted January 9, 2018 Author Report Share Posted January 9, 2018 It is hard to find JA333ES for parts at reasonable price, harder than JA555ES. What has happend? Quote Link to comment Share on other sites More sharing options...

kris01 Posted January 9, 2018 Author Report Share Posted January 9, 2018 Anyway there is still chance. In 2017 I bought one champagne JA333ES in excellent condition for 100CHF (even with box, manual and remote) as not working and made it work again.

sfbp Posted January 9, 2018 Report Share Posted January 9, 2018 Hmm.... looks rather similar to the AU board for a JB-940. Either you can pinch the components, or maybe make the whole thing work. Often there are busted JB940s on Yahoo Japan auctions, look in Buyee and FromJapan if I am right. Quote Link to comment Share on other sites More sharing options...

If they ARE the same (I haven't had time to analyse) then the only possible thing would be if there's a firmware in the big chip. But I have a feeling there isn't. There's not that much difference between 940 and 333ES, honestly. The BD board is likely identical with the same ATRAC/DSP chip (CXD-2662). The tray is definitely one distinguishing feature, and possibly beefed up Power supply and noise suppression. Jim had scathing words about the difference between 780 and 980QS, for example. Just about nothing except a couple of brass screws, he said. Quote Link to comment Share on other sites More sharing options...

kris01 Posted January 10, 2018 Author Report Share Posted January 10, 2018 If you get JB940 you can try to swap. Chip on Dig Board in JA333ES. is Mitsubishi M30805SGP http://html.alldatasheet.com/html-pdf/723/MITSUBISHI/M30805SGP/305/1/M30805SGP.html same chip is on AU Board in JB940 so maybe there is a chance.

I had to repair mechanical issues of both my JA333ES and JA20ES after a couple of years. Never had a problem with my JB920s or JB930, that have been running day and night for much more than 10 years now. Quote Link to comment Share on other sites More sharing options...

philippeb Posted January 10, 2018 Report Share Posted January 10, 2018 3 hours ago, PhilippeC said: Salut Philippe, And the W...1 ? The MDS-W1 is less robust. I own half a dozen of them, use them intensively for moving tracks and duplicating/defragmenting discs. I fully trust three of them, that always operate as expected. Other units sometimes fail to duplicate full discs at once, but succeed if tracks are copied one at a time. The W1 is a symmetric machine, that can copy from disc A to disc B, as well as from disc B to disc A. A machine that fails to copy in one direction will often copy correctly in the opposite direction, preserving the feature. My intuition regarding failures is that the W1 does not retry when it fails to read a frame. The missed frames are rather replaced by silent frames, causing very short sound drops in the copy. In other words, I need not check the copies made by reliable W1s, but I always listen to copies made by W1s I do not trust. Usually, erasing the damaged copy, and copying it again suffices to recover. That being said, let me repeat here that without the W1, I would never have invested in minidiscs, as I did 16 years ago. What does digital recording mean, if you cannot backup your own recordings? Quote Link to comment Share on other sites More sharing options...

Hi, Looking at the SM p55 CN701 (which mates to CN800 on p43).I don't know what type if loom this is, but as it looks to be double row from the PCB layout, maybe the connector is pin-in-body type. If it is, is it possible to swap around pins 7 and 9 in the CN701 mating connector? This will swap JOG0/JOG1 and possibly could correct your rotation direction issue. I've recently replaced a similar encoder in my Tascam MD-CD1, and also had to use a Bournes part because the Alps part with the correct shaft length is discontinued. Fortunately the Bournes was pretty much an exact replacement and works correctly (if maybe a little stiffer). Regards, Kevin Quote Link to comment Share on other sites More sharing options...
kris01 Posted February 14, 2018 Author Report Share Posted February 14, 2018 I think I want be messing around with the encoder. I leave it as it is. In fact in all my mindiscs decks I hardly use ams knob. Quote Link to comment Share on other sites More sharing options...
Deano11 Posted April 27, 2019 Report Share Posted April 27, 2019 Hi, Just trying to do the same fix (JA555ES) in terms of replacing the AMS encoder as shaft is broken, could I ask what Bourns encoder you used if you have the info available?

kris01 Posted April 28, 2019 Author Report Share Posted April 28, 2019 AMS knobs mostly die as a result of mechanical damge. I had same problem with my CDP-XA555ES during transport. Quote Link to comment Share on other sites More sharing options...
