  1. Sony Product Archive

    About a thrid of the way down this web page begins the Sony Walkman collection. Good Luck, hope you find it. http://pocketcalculatorshow.com/walkman/page/2/
  2. [FIND] Lever (Lock) Assy Sony MDS-JA333es

    You might try to epoxy that lever back together.
  3. TDK PRO Hi-MD

    The link shows what looks like some more dark ones. You might try the format again, maybe it didn't really reformat from HiMD. https://www.ebay.ie/itm/1x-tdk-md-rxg-xa-74-pro-minidisc-minidisk-sammler-for-collectors-rar/282380921914?hash=item41bf36ec3a
  4. Onkyo Hi-MD "Service Mode"

    Hi, Perhaps you may be able to get some info from here: http://www.hifiengine.com/manual_library/onkyo/md-185x.shtml It shows a link to download a partial service manual for an Onyko MD-185X good luck
  5. Have you sold both the R50's yet?


  6. LIP-4WM Battery Rebuild.

    Stephen, It may be that the LIP-4WM protection circuit may be a bit confused. I've had protected LiOn cells do this when they think there has been a short circuit or the output voltage gets to low. Just charging the cell gets it back operating again. I also bought a couple of those 350mah cells from the Ebay seller Jimma referenced and both of them were 350mah. Maybe I got lucky.
  7. mini disc without a battery

    If you don't have the remote attached, make sure HOLD is not turned on. If Hold is turned on then the display won't show anything and it won't play, it will just look like it's dead.
  8. mini disc without a battery

    I just removed the battery and put my NH1 (with remote attached) into the charging adaptor and It played just fine.
  9. will this battery work with the mz nh1?

    I have tried the "burn out" methods, including both the short duration 12v application to the battery and using a dumb charger like sony mz-r90/91 to charge. The battery does indeed get warm in the r91 during charging but didn't really fix anything. I'm sure some internal resistance can be reduced by these methods in some batteries depending on the conditions that caused the high resistance but it's just never worked in any of the batteries that came with any of the MD's I've purchased and of course none of the HQRP batteries. Anyway I'm pleased with the performance of the Sofirn NiMH's I'm currently using. Actually this post confused me. I didn't realize the OP was needing a replacement for the LIP-4WM. Should have looked at the topic closer. I wish I could report a good source for the LIP-4WM but they just don't seem to be out there. I keep thinking that some Chinese company will come out with a replacement but have not seen any yet, maybe someday.
  10. will this battery work with the mz nh1?

    Smart chargers can help with recovering some capacity (to a certain point) of the battery by repeated charge/discharge but can't do anything about decreasing internal resistance.
  11. will this battery work with the mz nh1?

    I tried the HQRP gumstick batteries and I never had any luck with them. They all had high self discharge characteristics and developed high internal resistance pretty quickly. The only NH-14WM replacement I've used that wasn't high self discharge is the Sofirn 3000mah battery from China. Don't let the name fool you , it's no where near 3000mah. Its like 1200mah but will hold a charge. The Sofirn battery is all white in color and its still going after a year now. It's not as good as the original Sony pr Sharp gumsticks were but way better than any HQRP I've ever tried.
  12. WTB: Sharp 4 Pole (1Bit) Clip on Headphones

    I have a pair. Sent you a message about them.
  13. I usually manually clean away the bulk of the residue then use a q-tip moistened with wet baking soda. Baking soda will bring back a neutral ph. Make sure everything is dry before applying power afterward. Looking at the service manual for the NH900, the negative contact for the battery (back end of the battery compartment you mentioned) appears to be on the main PC board itself. If there is leakage on the main board you may have to disassemble the unit to clean and repair any damage. Good luck.
  14. Might it be that the "converting" done is SS (for the wav file) is just the encryption being done while loading the file onto the device? This also might be why the file on the MD is larger than the PC since it would contain more information.
  15. Sony MZ-E900 Service Procedures

    The E900 Service manual talks about using CD and MO discs during the Test Mode (section 4.1 General, page 7). I can't find any information in the service manual or anywhere else that defines what a CD or MO disc is. I supposed that a MO disc was a magneto optical disc (a Minidisc) but maybe that's wrong. I have no idea what a CD disc is with respect to minidisc maintenance. Anybody done the power adjustments on the E900 or know anything about CD or MO discs? Once you have done the NV reset on this thing it stays in Test Mode forever until you finish the electrical adjustments and these discs seem to be essential to get thru that process.
  16. Sony MZ-E900 Service Procedures

    Good to know it makes a difference. I used a fresh alkaline Duracell AA battery (measures 1.521 volts) when I ran the CD and MO tests. Maybe that's not within acceptable limits.
  17. Sony MZ-E900 Service Procedures

    Good luck with your EH70. Fortunately mine has never given me any trouble (knock on wood).
  18. Sony MZ-E900 Service Procedures

    I have received the factory MD and gone through the CD test, MO test and have gotten out of test mode. But CD and MO tests fail with some lazer alignment error if I don't pinch the hing area when doing the test. It passes if I pinch it and fails if I don't. Maybe I'll take it apart and maybe accidently correct some mechanical alignment issue during reassembly.
  19. If you are referring to the chargers themselves, just do a google search and select images to see a billion pics of any of these charger/analyzers. The full names are: Opus BT-C2000, Powerex MH-C9000 WizardOne and La Crosse BC-1000 The links below are not the only places to get these (some have better prices) however I wouldn't get an Opus BT-C2000 anywhere else. http://www.ebay.com/itm/Opus-BT-C2000-Battery-Charger-Tester-Analyzer-NiMH-NiCd-AA-AAA-C-D-12-Volt-US-/331042777396?pt=Battery_Chargers&hash=item4d13afe934 http://www.thomasdistributing.com/MAHA-MH-C9000-Charger-with-4-Maha-AA-2700-Batteries-and-Holder-_p_1002.html http://www.lacrossetechnology.com/bc1000/ If you are referring to my particular setup then here are some pics of that: One set of wires are connected to a AAA to AA cell adaptor with a wooden dowel representing the AAA cell inside the AA housing. The other wires are bare but can be placed at the ends of one of the AAA to AA adaptors when its put into the charger slot.
  20. what you have and what you had

    Ok, here are a couple of pics. Took me a long time to figure out how to post pictures, even though it's easy.

  22. Sony MZ-E900 Service Procedures

    Good to here that your unit is functioning ok. No idea what's going on the the two LP2 discs. I'm still waiting to receive the factory made MD so I can get through the CD tests and get out of Test Mode on my E900.
  23. For older NiMH batteries or those not used in a long time, use the refresh mode to restore them to optimum capacity. Did your BC-700 come with any instructions? I have the BC-1000, Maha C9000 and the BT-C2000 charger/analyzers. For charging gumstick batteries, I modified an old sony BC-7DC2 charger to work with these charger/analyzers. I gutted the BC-7DC2 and soldered wires to the battery contact terminals and brought them out to connect to the BT-C2000 charger (or either of the other two charger/analyzers I mentioned). I can now charge two gumstick batteries at a time using a battery holder built for them. My old home made holder worked but not as good as the modified BC-7DC2 solution. I personally prefer the BT-C2000 charger because it can measure battery internal resistance which seems to be problematic with these gumstick batteries.
  24. Sony MZ-E900 Service Procedures

    I'm going to get a prerecorded MD anyway but does the tricking firmware procedure require dissembling the unit?
  25. Sony MZ-E900 Service Procedures

    That sounds good if I can't do anything with mine. I will be around, I usually check the new posts daily. I just bid on a prerecorded MD so at least I'll be able to get thru the electrical tests and get out of TEST MODE. I don't really know if this E900 is dying or just out of some adjustment. Before I erased the NV ram, I noticed that there were several error codes (abnormal spindle error, real data error and focus off center) recorded but I attributed them to a mechanical disorder of some kind because if I squeeze the back hing area when starting to play a MD it will most of the time start playing. But if I don't it just rattles around for a while and says NO DISC on the remote.
