TOC Reading Posted February 2 Report Share Posted February 2 I have two Yamaha MD8 multitrackers, one works fine, the other has recently displayed "Error 08" and the disc tray can't be opened. Not a single key on the machine will do anything, nor does unplugging the power lead and then reconnecting. The user manual says Error XX means a "fatal error occurred, contact your Yamaha dealer". Is there anything I can try myself? Quote Link to comment Share on other sites More sharing options...
BearBoy Posted February 2 Report Share Posted February 2 Hello @TOC Reading. I wondered if the Service Manual might shed some light on what the various Error codes relate to but unfortunately it too just states that Error XX is a fatal error and to contact your Yamaha dealer. If it's any use, you can find a copy of the Service Manual here: https://www.minidisc.wiki/_media/equipment/yamaha/pro/yamaha_md8_recorder_service_manual.pdf I did find this list of error codes on another forum but unfortunately the links to various Yamaha support pages it included now appear to be dead: Quote MD ERROR CODES Error Code Description Disc Error 01 Recording Re-try Failure Disc Error 02 Recording Data Overflow Disc Error 03 PLAY Data Lack (to indicate data overflow during Recording) Disc Error 10 Address Inconsistency during Recording Disc Error 80 or 08 The magnetic head didn't drop into position. Error 01 Sled (or laser unit) didn't move to the inside position. Error 02 Sled didn't move to the outside position. Error 04 The magnetic head didn't raise off of the disk. Error 05 Spindle Error Error 06 Focus Error Error 07 Tracking Error Error 08 The magnetic head does not search An error code on an MD Recorder is not necessarily an indication of a problem with the unit. The error may also be the result of inconsistencies in the MD media itself. Before contacting Yamaha for repair, a different mini disc should be tried. However, if the error occurs repeatedly on multiple mini discs then the unit most likely will require servicing. Arrangements for servicing can be made by contacting yamaha Customer Support at (714) 522-9000. Link: LINK Quote Link to comment Share on other sites More sharing options...
BearBoy Posted February 2 Report Share Posted February 2 Also found this: Quote The error 08 generally means that the disk is physically "stuck". This can be caused by the door not being closed completely. So please turn off the MD8 and turn it back on, making sure the drive door is shut ALL the way. Press with a little force if necessary, at least long enough for the machine to recognize that the disk is in so it can eject it. This can happen sometimes when the door is not completely closed, in which case, it's not really a problem - just something the MD8 does occasionally. If you get an 07 error after that, just do the same. LINK Didn't fix the person's issue in that instance but might be worth a try? Quote Link to comment Share on other sites More sharing options...
sfbp Posted February 3 Report Share Posted February 3 (chiming in with the alacrity of the profoundly ignorant, as I have never even seen one of these) Either there's no signal from the head, so the servo system doesn't have the inputs to process feedback, OR the cog on the lateral sled that moves the head is stuck (calcified grease?) or, worse, broken. If it was recently writing, you are in a pickle because it looks to me (again, ignorant) that the design resembles the portables rather than the decks (of Sony), and there is probably a locking mechanism (on the whole drive) for when the write head is engaged ("dropped" in the words of the manual quoted). If so, it's very tricky as you will end up taking it to bits before that will release - unless you can find the right bit of metal to push so that the lock comes off. This is how portable units get permanently damaged, by trying to jimmy the locking mechanism. I know, I've done it. I think you need to see what position the head(s) is(are) in both laterally and vertically. It it possible to show us a picture by unscrewing the protective cover on the drive? Also you may be able to see the problem yourself if you open up BOTH your units in the same way and see what's stuck (i.e. not moving!) on the busted one. You also need to understand the pictures on page 65 of that PDF (it's numbered "5" so this PDF is several documents in one file). In particular it would be nice if there was a problem with the arm/rod/switch at 160/170. You might consider something like this (and there are other listings there): https://www.ebay.com/itm/196223789471 For parts, and the fault, that it has, may well be different from the fault that yours has. In any event the spares will be useful, especially if you have two of these and want to keep them going indefinitely. Or you could buy the whole MD mechanism (but of course a complete replacement unit may be just as cost-effective). KML 252 AAA. https://www.ebay.de/itm/353216727287 Sorry this is probably useless waffling by me. Good luck! Quote Link to comment Share on other sites More sharing options...
