sfbp Posted December 17, 2010 Report Share Posted December 17, 2010 I think you crashed them, to be sure If you simply followed the service manual, you are out of luck, as the first thing it tells you is to reset all the NVRAM settings. Unfortunately if you do this, there's no real simple way to recover because now you will need all kinds of equipment to recalibrate the device. And an alignment disk which even I (who have the equipment) do not possess. There's somewhere in one of the manuals a recipe for making an alignment disk, but I have no idea how reliable it is; in any event one will needs a perfectly working machine first, to make such a disk. If you can get into service mode there is some hope; but ONLY if you know exactly what you did, so that we can undo it. Generally the service mode stuff works, but if you save some invalid setting without knowing what you are doing, you have set yourself up for everlasting grief. Sorry. Welcome to MDCF!

sfbp Posted December 17, 2010 Report Share Posted December 17, 2010 There's a guy in England who is more than capable of fixing most portable MD units. You can find him on ebay. Obviously you will need to make special arrangements about postage if you are not in the UK. What was the sequence of events? Was it working perfectly, then you tried to get into service mode to "hack" it; or was it because something failed that you tried to get in and change things?
