I recently powered down NVX and removed cables and bays before unscrewing and removing sides and top covers and cleaning dust with compressed air can. I've done this successfully before, following a detailed video which I think was produced by one of the 'jedi council'.
It was in-depth and concise and I originally had no problems; this time, however, after replacing everything and allowing time to settle, attempts to power up were negative. I've made subsequent checks but can find no solution. My only conclusion is that I may have damaged the hardware somehow with the compressed air.
Can anybody solve my problem? Any help welcome. Also, if I need a replacement chassis, any advice and tips on where best to find one will be welcome.
It's possible you damaged something, but probably not with the air. Maybe bumped into something?
Or, and it sounds a lot like it could be this, it's not something you did other than turn it off. If the power supply is going to fail, it's usually going to do so on a power-on attempt. Same with a lot of other possibilities, but an NVX power supply is a little long in the tooth and a very likely candidate. The count of failed NV+ PSU's is growing here, and the NVX uses the same one and is of a similar generation.
I'm not able to upgrade or migrate right now due to finances and the fact that my NVX (my only NAS) won't power up, plus I need to get it running as soon as possible.
Sandshark, after posting initially I checked a few threads on the same issue, including posts by yourself, with mention of and link to correct PSU, setup, price, specs etc. I can't remember what was where or what applied to me. I'm UK based, if relevant to purchase and/or compatibility. If you could provide the best (and hopefully cheapest!) link to the specific PSU required, as well as required specs, it would be a god-send!
I recall reading nightmare details of PSUs that didn't quite fit, followed by mention of aluminium, duct tape, drilling holes in the casing. I have to avoid all of this at all costs!!
If the disks are fine, the array is fine and the volume it should be straightforward to use an ordinary x86 Linux machine to read the data at your own risk. You would need to install mdadm and lvm2 if they are not pre-installed. You should check disk health and the state of the RAID before trying to start the RAID using mdadm. Then scan for the volume group, activate the volume group and mount the volume read-only and backup the data.
You have multiple different options. For many using a new x86 ReadyNAS to mount the volume read only and backing up the data as explained in the article I linked to above would be simplest.
mdgm: Other than my NAS, I haven't made the leap yet of converting to Linux, so what you're proposing would be too ambitious for me at the moment.
StephenB: Your second link states it doesn't come with a tray. Does that mean it just lays on the existing tray and slots into the back as displayed on the opening image of the embedded video of the link?
I notice also that the power cord would be inserted at 180° to its default position. Not an issue?
I also read about the additional fan, vent holes, blockage etc. Will there be additional strain, ease or no difference on the NAS as a whole?
Finally, for peace of mind, does this PSU fit perfectly and not have any of the issues I read on other threads requiring aluminium, duct tape etc.?

There are several other posters who reported success (using various NAS), I'm not seeing any of the issues you are concerned about on their threads. Of course I might have missed something - hopefully a community member who has used this supply in an NVX will chime in.
I have a Pro Biz edition that took a couple reboots due to UPS issues. After the first power on it came up, the power went right down, then back up and the NAS didn't. I assume the PS and from what I read here, they are unavailable, but there is a similar PS that needs to be rewired?
I saw the schematic showing the wiring but although I am a part time rocket scientist, I am lost on what to do.
Is there some kind generous person who could make a replacement PS, for payment of course?
I have about 12TB of data, most of which I can't replace.
2. I read somewhere about a PS that is compatible in size but needs the wires changed?
The drawing showing the two connectors and the difference in wiring vs. a standard ATX connector didn't make it clear what you changed to make it compatible?
I didn't mean to sound I was shy of a soldering iron as I am building an electric trike, but I couldn't figure out what I needed to do from the info I found.
What you need to do is remove the -5V (white) and -12V (blue) wires and replace them with +12V (yellow). If it's just a temporaty thing, then adding only a single additional +12V is typically enough, so it can all be done in a 24-pin to 20-pin ATX adapter just by pulling and swapping some wires because the 24-pin connector has one additional +12V wire over the 20-pin.
Thanks, it was that explanation that I needed but to be clear, I understand that the existing -12V on 12 and the -5V on 18 will be snipped, tied back, not used. And then those connectors will be substituted with a +12V source. Does that mean I can tie pin 10 +12V to the stubs from pins 12 and 18? Os that single 12V source sufficient for what was three sources? Although I suspect in the supply all three +12 tied to a single output.

Yes, all three MUST be tied to the same thing in the supply. But the three wires are there for the current capacity, especially the connectors. If you are going to solder, then you would reduce the resistance on one side by having three pins and not lose much in the splice. If you are just planning to twist them together, you are worse off doing that than leaving just the one wire, as the resistance of the splice will be higher than the gain in the redundant pins. Whether one is enough would depend on the current draw of the drives. I wouldn't count on it for long term, especially with older, power-hungrier drives. The better way would be to connect Pin 12 of a 24-pin connector in place of one of the removed ones. For the best connection, pull the pin and swap it, don't cut and splice.
