RNDU6000 doesn't boot - Stuck on "ReadyNAS" prompt screen
Dear all,
My ReadyNAS Ultra 6 doesn't boot anymore, both with and without the disks inserted in their slots.
No special soft or hardware update action was going on.
Sometimes things restart after a while but not in my case, Raidar cannot see it and I cannot access the boot menu. Nothing looks broken so I believe something must be corrupted somewhere.
It looks like this issue is common on the community but without explicite solutions, only the one below is marked as solved:
Can someone give me a hand?
I'm out of warranty for a long time. I'm using my 10To capacity in RAID for backup purposes.
Considering the PSU is working as well as the hard drives, and nothing looks broken or burnt I assume my issue can be electronic only and no repair is possible, neither spare part available on internet. So I will stop investigations here and just replace my NAS.
By the way, as I cannot recover any data, I will migrate to Synology as I'm not an IT guy and the Netgear interface has been a nightmare for me when Synology is famous for the friendly interface.
Thank you for your help, at least I'm now sure I didn't miss anything I could repair before breaking my piggy bank.

The post you linked to has a different symptom (stuck on "Booting... checking root FS" with disks installed). Are you seeing that, or just "ReadyNAS".
Assuming you are just seeing "ReadyNAS" with and without disks, then most likely your problem is a failed power supply. If the 5 volt output of the supply is working but the 12 volt output has failed, then you will see the "ReadyNAS" prompt, but nothing will work. It is possible to replace the PSU with some effort - Sandshark often gives helpful advice on that.
Another option is to purchase a new OS-6 NAS (RN300 or better). OS-6 uses a very different file system, so you can't just migrate the disks from an Ultra running OS 4.2. But you can mount the existing disks temporarily, and copy the files to external drives. When that's complete you'd do a new install, and restore the data from the backups. https://kb.netgear.com/29957/ReadyNAS-Migrating-disks-from-RAIDiator-4-2-to-ReadyNAS-OS-6-x86
Thank you StephenB
Indeed I can only see "ReadyNAS" on the front panel.
I didn't know were 2 different power supplies so wasn't considering that as the fan and front panel were working.
So right now I will work around the 12V power supply which sounds something I can afford.
I will look at @Sandshark replies but any pointing to the right direction is welcome.
I may still consider a new sever, but more to backup the first one in case of failure as raid doesn't look enough to secure my data :-)
It would be also very hard to clean and migrate 10To of data :-(

It's just one supply, but has both 5v and 12v outputs (generally PC PSUs have both).
I've never owned an ultra-6, so I don't know first hand how it's supply and internals compare with the pro-6 that I do have.
There is a useful guide on getting the PSU out of the pro-6 here: https://community.netgear.com/t5/ReadyNAS-Hardware-Compatibility/ReadyNAS-Pro-6-Power-Supply-FAN-replacement/td-p/1072881 It's not quite on-target, as the poster was actually disassembing the PSU to replace the fan inside it. But it does show the basic steps needed to get the PSU out of the chassis. Note the warning about accidently knocking off one of the heatsinks in step 5. Even with the warning, I did that. If you do also, then don't use the arctic silver repair that the OP suggested. You should use 3M thermal tape instead (I purchased mine here: https://www.amazon.com/gp/product/B00MO2XEGE It was easy to apply, and worked great )
The stock PSU in the pro-6 was a Seasonic SS-300SFD 300W. However, those aren't easy to find. Sandshark suggested a Silverstone SST-ST45SF here: https://community.netgear.com/t5/Using-your-ReadyNAS/ReadyNAS-Pro-Pioneer-getting-power-but-blue-power-button-not/m-p/1550197#M144442
Those are still available, and cost about $60. However, you likely will need to modify the cabling some. You'll need three molex outputs (at least you do on the Pro-6), and as you can see from the pictures in my first link, the space for the cabling is tighter than it would be in a normal PC chassis.
I'm not a hardware guy, so hopefully Sandshark will chime in and correct any mistakes in the above. (And hopefully someone will verify that the RNDU6000 has the same supply and physical layout).
