MZ-RH910 does not work with freshly charged battery

I have a couplke of Prismatic 1450 gumstick batteries and an external charger. The MZRH910 will not work with a freshly charged battery unless i first connect the Sony power supply, turn the MD on and off again, then disconnect the power supply. It will then work as normal until the battery is re-charged. any ideas?

Sony d-ne900 Walkman gumstick rechargeable battery doesn't can I charge it?

If it does not charge, the issue lies with either the charger or the battery.

Even with a freshly charged battery, my coolpixs570 will not turn on...are my batteries dead? is my camera in need of repair?

It could be the batteries. It could be the battery charging circuit in your camera. Try charging the batteries in an external charger that you know for a fact is working properly. That will tell you if it is the camera's charging circuit or the batteries. If it is the camera's charging circuit, it will cost less to use an external charger then to repair the camera.

It maybe brand new, but we don't know how long it's been in the box.

You will need a DVM to troubleshoot the battery.

Cannot charge MZ RH910 through usb

Possible that there is fault within , can be a faulty battery, corrupt memory or a hung up processor. Try and reset if not the player has errors. It must switch on with the power connected if the battery is low.

My MD player does not operate? No display coming on the screen. Power is connected ok

Unfortunately if it's getting power but not responding there is little that you can realistically do. When you state "Power is connected ok" I presume that this means you have already tried using the gumstick rechargeable battery (which doesn't last forever, BTW), and also the charging stand. If you have tried both of these, then it's clearly not an obvious fault such as a broken power input socket. You can also try connecting the optional external dry battery case, but this was an optional item with the N-710 and rarely purchased by users, or you can try disconnecting the ac adaptor from the charging stand and connecting it directly via the socket on the player marked DC IN 3v.

The fault is likely a really simple one but the MZ-N710 and almost all other portable MD players were never designed to be repaired and consequently are really difficult to dismantle without causing more damage. When I used to sell these products I was told by the Sony servicing centre that for all but the most minor issues warranty claims were dealt with by destroying the returned unit and sending the customer a complete replacement.

Spare parts were not commonplace when the units were a current model, and now they're as common as freshly laid dodo eggs. Your only realistic fix is to replace the unit.

This may sound negative, but it's not: because MD is now an obsolete format there are millions of perfectly good units lying unused by those who have upgraded. Except for the later and far rarer HiMD models and also flagship regular units like the MZ-N910, almost everything else is near worthless so folks tend not to bother with selling them. As a result it's quite easy to pick up MD equipment for free via your local FreeCycle and Freegle groups; apart from my own MZ-N910 (still in regular use and has a far superior sound quality to any iPod) every piece of MD gear I own was obtained for free, usually with loads of minidiscs as well. Don't be too choosy about what you may be offered as most of the Sony NET MD players (any MZ-N model) can be easily hacked to give them most of the features of the flagship MZ-N910.

If you do end up recycling your MZ-N710, then keep all of the accessories as they can be used on other players which you might acquire.

I hope that my answer has been of use even if you cannot fix your player. Please take a moment to rate my answer.

I have a Sharp MD-DR470H Minidisc player with a gumstick battery, i cannot find a charger anywhere, can you please help.

I've deliberately avoided answering your question for a few days to see whether someone else had located a gumstick battery charger, but clearly they have drawn a blank as well. They were never a common item even when Sony sold them new.

You may wish to do as I do: I use broken MD players as chargers. There are millions of MD units lying unused, most are worthless now and many are broken (typically the fatal TOC error). As a result it's easy to get them for nothing on local FreeCycle and Freegle groups and often they come with spare discs, batteries and other accessories. best of all, most of them are still in working order so you may even end up with a free upgrade. Every bit of MD gear I own has come from FreeCycle and Freegle except for my superb MZ-n910 which remains in regular use.

As luck would have it, I was about to hit the "Post Solution" button when I found this one on eBay. It wasn't there when I last looked! it will hold two gumstick batteries.

Battery for sony net md walkman mz n710

You have to charge it with high voltage, external power unit to get the fine result of charge or buy a new battery

The "gumstick" battery you're referring to is like ALL other rechargeables in that it does not last forever. If you're certain that the charger is working then just buy another battery.

If you're in the UK then I highly recommend the Small Battery Company. Be careful if purchasing from Amazon Marketplace or eBay as there are plenty of underperforming fakes around.
