I've been using my ReadyNAS RN31200 for many years now with no problems whatsoever.
We had a powercut today and when the power came back on, the fan on my readynas is spinning loudly but there are no lights at all on the front? If i turn it off and switch it back on, the power light flashes for about 10 seconds, then goes solid blue. After about 5 seconds it flashes once then goes off altogether and won't come back on. It just sits there with the fan going.
RAIDar can't find anything and i have also plugged it directly into my laptop but still no joy
Any ideas on what it could be or how i can fix it?
If you purchase a new ReadyNAS, you can directly migrate the disks. It's best to get an RN420 series or better (those are x86 platforms like your current NAS). The RN422 is the replacement for the RN312 (which was discontinued some months ago).
I have tried it without disk(s) as well and still nothing shows up in RAIDar
It sounds to me like either the chassis or the power brick has failed.
If you are the original purchaser, then I recommend checking your warranty status at my.netgear.com, and if you are still covered then initiate an RMA from there ("replace my defective product" on https://www.netgear.com/mynetgear/portal/myOnlineTicket.aspx).
If you aren't covered by warranty, then you could try a risk-buy of a replacement power brick (3rd party adapters are available for about $20 US on Amazon).
I don't own this particular model, so I can't search on the details of the brick specifications (amperage, voltage, connector, polarity).
There are several options shown on the US amazon site (searching for RN312 power adapter), but they don't show up on the UK site. If you can't sort out the specs from your existing brick, you might need to go with international shipping - unless someone here chimes in with a UK link.

Yes. Again, this is a risk buy - we don't have enough information to know if the problem is the power brick.
Of course another option is to replace the NAS. You can directly migrate your disks to an RN422 for instance (or any RN400, RN500, or RN600 ReadyNAS).
it is the image posted by @jonaldo that I cannot see
I understood that. The forum software will automatically quarantine some images (as part of spam prevention). When it does that, I can still see them, but others can't.
Once you mentioned that you couldn't see it, I realized that his image was still pending approval, so I went in and released it.

I hooked up my NAS to my tv using hdmi and have attached a picture of what it shows when trying to boot with no hard drives in and without any usb stick in ie the error as reported in my first post.
I have also tried booting with a USB stick, i think i am doing it correctly for my model, i'm holding down the backup button when turning the NAS on. The screen shows 'american megatrends' then just hangs stating boot error. Not sure if it's the usb stick so am trying another as i type.
That photo would suggest that the NAS was doing a normal boot (you can see the kernel version is the one for 6.9.3) not booting off your USB key on that attempt. You can see in the Call trace the words "mount_block_root". On systems with a display on the front that snippet of the Call trace would be shown.
USB Boot Recovery is the solution for this particular problem. USB Boot Recovery is very rarely the solution to a problem, but in this particular case it is.
