Where can I find a new battery for my old Lyra RD2840 40GB mp3 player

It is entirely possible to open the player and access the battery, however it will not be cost effective as this is a fairly old player and the replacement battery will be near impossible to locate.
as for new MP3 players, I would recommend the Sansa Clip as it has been rated as having exceptional battery and sound quality, it will meet your music needs and can be had for less than $30USD.

Hope this helps.

If you have fully charged the device with the power cable and it still will not turn on, it is likely that the battery is no longer holding a charge. You would have to contact Sylvania to ask about battery replaement, but it may be cheaper to purchase a new device.

If even affer charging for a long time the battery is draining off you will need to change the battery. Remove cover carefully test and confirm before you replace. attempt only if familiar and to do it carefully.Good day

If your unit is around 18months or you are a frequent user (over 500 charge cycles), the inbuilt Li-Ion battery will need replacing as it has probably gone past its useful life and therefore is no longer holding a charge. The internal 'mechanical' HDD is particularly savage on the battery.

The clicking noise is a symptom of a damaged hard drive.

This mean that the only solution is to replace the hard drive.

Your best option is to buy a partially working X3000 media player and use its hard drive to fix the one you have, or have somebody in finding the specific 1.8" 20GB hard drive your mp3 player has, but also such person will need the booting and firmware files to put them in the new hard drive, otherwise it won't work.

Best regards,

The tiny LED where you plug the charger in should turn from red to blue when the LYRA is fully charged. If it stays red, I would have to say that you need a new battery. Search for an NP-120 or a D-L17 camera battery on the web. It will work as a replacement.

Hi,

It looks like you need new battery.

I'd start by replacing the firmware on it. I believe this may be the firmware for your model. http://drivers.softpedia.com/get/FIRMWARE/Lyra/Lyra-Mp3-Player-RD2760-firmware-207.shtml

There are available battery at radioshack or bestbuy. Check some of your local electronic stores.
