readynas nv+ won't power up

If the only goal is offloading data, then I suggest connecting disk 1 to a PC, and using R-Linux for Windows (Freeware) to offload the data.  You can connect it either with via SATA or with a USB adapter/dock.  https://www.r-studio.com/free-linux-recovery/.  If R-Linux doesn't see the data volume, then try again with disk 2.

 

You haven't said how long it's been since you accessed the NAS - if it's been a while, there are some challenges getting access to the network shares using Windows 10 or current MacOS systems.  Your NAS uses SMB 1.0, which is being deprecated by both Microsoft and Apple.  There is a workaround to enable SMB 1 in Windows 10, AFAIK there is no workaround for MacOS.

Or are there problems with this approach, like the network configuration and other things that the ebay unit will have ? Would it be ok to get the previous owner to do a factory reset ?

One aspect here is that you need the original NV+ (called v1 here).  There is a replacement platform called the NV+ v2, which is completely different.  The labeling is very confusing, and many sellers (and buyers) make mistakes and get the wrong platform.  

 

But to your question - all the configuration files are stored on an OS partition on the disks, so there is no need to have the previous owner do a factory reset.  But you should first do a factory install with a scratch disk.  Then check the firmware - and if it doesn't match what you were running on the failed NAS, then you should install the matching version (or update it to 4.1.16).  I also suggest checking that NAS will boot up with the scratch disk in every slot.

 

The reason for matching the firmware:  If the firmware in the NAS flash doesn't match what is on your disks, then the NAS will attempt to upgrade/downgrade your firmware to whatever is in the flash.  If the firmware image in the NAS is very old, that can cause problems - because some downgrades aren't supported.

I also noticed I can get a replacement power supply from a local pc parts company - can anyone suggest if this is a better approach ?

It's hard to say if it is better or not - it depends on the overall condition/health of your chassis, compared with whatever replacement unit you end up with. 

 

Make sure the replacement PSU is intended for your NAS.  A stock supply needs to have the pinout modified a bit, so you need to know if that has been done with the replacement.
