You have to desolder the main board, you didn't need to take the whole mechanism out..

EEEUUUUUUMMMMMM TO MUCH

The architecture of the Visualize fx cards are covered in HP Journal from May 1998. Not mentioned in the article, but one of the things I remember about it is that a bunch of the chips in the fx cards are just additional specialized PA-RISC processors.

Hi, First of all love your videos reminds me why we got into this format even though it has mostly been forgotten there is something we all love about Minidisc that adds to any system. A little while ago I bought a JB940 Sony from the UK as I am in Australia to replace my other unit, That was just too past it to fix . I received it and changed the plug for Australian electrical and it seemed fine for a while (3 years)just recently when it gets turned on it just tics No display and just wont power up properly as you have dealt and fixed many minidiscs could you share some light on what might be the problem I do have a very good repair place that I use that I could send to JVP Service Centre in marrickville nsw but if it is something you thought I could tackle Myself that would be good. Thank you Look forward to your response Dennis

Amazing!!! Where did you order the belt part?

Thanks for the memories! Back in the late 90's / early 2000's I was in charge of a network of CAM workstations that ran HP-UX. The last HP-UX machines I bought were HP C3000's and HP C3600's running HP-UX 10.11 if I recall. Around 2004 our CAM software was ported to Linux so I switched over to Red Hat machines in 2005 and relegated the old HP workstations to terminals for manufacturing machines out on the shop floor. Even though the OLD workstations were workhorses the Linux machines were an order of magnitude faster in all regards and cost 25% of what the HP machines did. Having said that, in 2007 I had a Dell RAID server running Red Hat that corrupted the whole disk array due to a firmware issue in the RAID controller. I'm confident something like that wouldn't have happened on an HP RISC-based machine.

Hey Nick was wondering how you put the ear cups back

Well done tackling the input switches. It's still a great looking amplifier. Thanks for sharing this.

Thank you, this made the job very easy! My JB940 developed this issue and at first I thought I had no chance of bringing it back. Found your video, found the new belt online, replaced it yesterday and it’s working perfectly. I have already started using Audacity to get some recordings from my discs that I know I can’t ever get anywhere. I’m a happy camper! Many thanks!!!!

I have the exact same model with the exact same problem. I also have sausage fingers, no idea about electronics, or have the tools you have. If I can send you mine, can you fix it? I'll happily pay you to fix it of course

If you prise the ear cup off at the opposite side to what you did in the video it does not break the lug/hole if you are careful. @ 1min onwards. Use a flat blade screwdriver and push it in till it pop off.

Hi Nick. All inputs HDMI inputs have blown and no longer work on that model...Any advice for me please?

The same thing happened to my TS100 while I been ill for some time and not used it for ages it just lost it's brightness it's a mystery why as it's been sealed in it's case ? I have linked to your video as when I get a new display I have to follow your tutorial.

cool stuff! Today I cleaned up my hp C3600 "Bastille HP-UX 11.11 Jumpbox", setup & used back in 2007 for a T-Mobile project where we deployed a very swanky Sun Cluster WAP gateway. Due to good T-Mobile IT Security constraints (no data out possible from the attached T-Mobile admin linux boxes in Bonn HQ). I used this workstation for reverse tunneling (I am Civil Engineer ...) from one of the WAP Gateway Front-End Server when connected to the internet "home", so I could finally 'grep' the complex system configuration for documentations. I again forgot root password after longer no use, and due to "Bastille" security setup it is a quite tricky thing to reset root password, especially 'cos I havn't touched HP-UX for centuries. But finally I could fix it. Think I got nearly 10 boxes (plus 3 a-class servers, but also several x86 VISUALIZE X-CLASS & X4000 Workstations) of these brave nuclear attack prune PA-RISC HEWLETT PACKARD Workstations. (HEWLETT PACKARD & its "HP-Way" rest in peace) My C3600 got the fx10+ GA and 2 IBM 9 GB Drives.

That DAT is for the AIWA NSX-D9

I have the same symptoms. The problem is caused by the Mute switch that operates when the microphone boom is rotated.

Hi Nick, I've been watching this and your last video with great interest because it seems to be the only video about a hp-risc machine that involves graphics output and hp-ux on youtube :D I'm currently trying to get a HP Visualize FX10 pro to work in my HP3000 A500 server, which seems to be the exact same hardware as a HP9000 A500 server. And these machines share the same architecture of the C-Series workstations. I just could not manage to get the console redirected to the graphics card and also none of my USB PCI cards seem to be recognized by the system... Could you maybe take a look into your machine and try to find out which kind of USB controller chip it is using? Because without USB I have no way to connect a keyboard to my machine since it has no PS/2 or USB connectors onboard. I'd be very thankful :)

So, so long since I installed and used HPUX on anything I’m not remembering any of this 😂 That would’ve been on Stratus/Ascend/Lucent DNCP machines rather than actual HP kit, soon after the turn of the century.

Hi Nick, I don't have any HP-UX 11iv2 software but I do have some 11iv1 CD-ROMs including application software, from 2005

hp just did their own thing . the gfx sandwich was display out ramdac / framebuffer card with texture processers daughterboard .

Perfect, Nick! Thanks a lot!

Hi, thanks for this good video ! do you have any idea to fix the small plastic piece here at 1min21 th-cam.com/video/9rXG-q4isHs/w-d-xo.html when its totally broken or even missing/lost ?

Thank you man!. But vp150 battery has 150mAh capacity. And original have 500mah capacity. This change dont work for the long time. After some charge-recharge cycles you have error battery again. Use battery capacity 500mah and more then. I use 700 mah 4xAA 4.8v battery for example GP T393.

I just wanted to say your idea of how you made the replacement brakes was pure genius! Well done!

Fit a silicone belt it will never go bad again

I have 2 decks from different generations, and 1 still works good, the other same issue. With the amount of mini disc decks that Sony made I have no idea why they couldn't make a better eject mechanism

Great vid was in exactly the same place with my Lab server. Replacement battery again worthless upon receipt. I thought about dumping the Battery altogether but that of course disables Array expansion. I installed the same battery as as you have, except i also added a battery connector so if i ever need to swap again its just a pull and replace. Sure the batteries are not of the same spec but it seems to take ok. Having never soldered anything I wasn't sure how id get on but it seems to be good and I've just added an additional 2 drives and its extending happily to itself !! Cheers Mutchly

What is this..???

Very instructive video thank you. This generation of tape player are really painful to maintin compared to older ones. And i cant see any great benefit regarding their complexity. Did you buy your belts from techdeck , fixyouraudio or did you use "random" chinese ones ? Thanks !

This is a headache of all Sony stuff with this type of switches. I had the same at 640th, 930th MDs and even at XA50ES CD.

Once again a big thank you Nick for your video and for you support, belt changed easy the player now eject the disc nice and smooth. 😀 Also I have changed the belt for the Sony SACD player. The tray opens and close perfect. Keep up the good work!

Hi. Thanks for the excellent video. Does the screen remain on constantly while the iron is in use? Can you estimate how many hours you used it before it became unreadable? Thanks.

Hi Nick. Thanks for your video. I have received an unexpected present from a friend, the same player like yours with exact the same problem. I have order the belt and hope to solve the problem. The player is ok but to force the eject I insert other disc and push gently the one inside.

Actually you can do that without removing the mechanism check Techmoan recent video

Thanks for your video, Nick. I'm actually considering buying one of the these Alpha 2, so with regards to the sound, what sound signature would you say it has? I'm into vintage gear (Sansui, Technics, Sanyo) and would like to know if this amp can compete with my Sansui au 117 and au 217. Greetings from Madrid!

Espectacular !!! Gran Trabajo !!! Gracias a este video voy a tratar de repara mi AIWA XD-S1100 que tiene el mismo mecanismo. Muchas gracias !!!

Hi Nick. Thanks for sharing this. I have the same player that had the same problem as yours. The disc wouldn't eject but it was playing OK. Just stuck in the tray. I removed the disc tray the same way that you did. When I replaced it back as it was, it wouldn't work. I just get a continual clicking noise as described below by another owner who has the same clicking problem. I didn't do any rough handed work. I even wore an anti static wrist strap while working on it. You have mentioned below in one of your answers to a question that it could be "the relay that turns on/off power to the main circuit/display, controlled by a microcontroller and its own small power supply."...........As I said my one was working OK until I changed the small belt. Do you have any idea what the problem could be ?. I am thinking maybe I have damaged a ribbon. In hindsight I should have left the disc tray in the until and not removed it. It is quit easy to change the belt without removing the tray mechanism and risking damaging the ribbons.

Please i search fuse for arcam 2. Very thanks

My test disc: Smoke Fairies (see th-cam.com/users/smokefairies)

When Sony was Sony.

The drive seems to be identical to my Je640, thougt the QS series might use more advanced one. The main difference seems to be the linear powers supply(at least i think so) with a R core transformer where my has a simple Switch mode board.

Thank you! Got old faithful working again thanks to this guide.

Any chance you could link that battery pack? All I found are either out of stock or discontinued. Appreciated.

Hi there I have a mds jb940 with no power when I switch it on there is no power but there's a clicking sound Coming from a black box in between the two transformers. Any ideas what it could be please. I'm in North Wales UK

How do you get it open????

I said "heat sink" but really it's not - it's just a RF screen Update: While the TV seemed more reliable for several months, it recently started playing up again. A fee reboots again, but also strange UI hangs: it would freeze in the middle of a UI transition in a most peculiar way. 20s later it would come back. Or perhaps not. I got a new mainboard off eBay (1-889-202-2) for £15, and for the last few days it's behaved perfectly. Procedure: unscrew mainboard and tuner board. Unplug tuner board from main board. Most of the connectors can be removed easily, but the video ribbon cable is tricky. Just pulling managed to damage the corner lugs of the cable so when putting into the replacement board it's hard to line up. The first time I failed and got no picture. Second time I managed to get it back in exactly in the centre, and it's been perfect since.

What is the belt prodect number I got the same player

Thank you for sharing sir new supporters here
