TS-669 can´t boot

[zplitt]

Hey guys!

After i moved to a new apartement i set up my NAS and now it wont boot. Before moving it worked fine.
When i press the power button, the display shows "booting system", the fans are on full rpm and NO beep. After about 7 seconds it turns itself off and tries to boot again after three seconds. Then it stucks on booting with fans on full rpm.
Same result with and without HDDs, without any beep.

My first thought was a broken DOM, because i had a similiar problem with an TS-469.

Could it be the DOM? Any other ideas?

Thank You!

Haha, yes, but even with the display failure it ran well. Now it wont boot at all. That there is no beep at all makes me curious.

Have you tried a firmware recovery?

Moving back to the previous apartement?

No chance, but thanks for the laugh!

I already threw out the DOM and flashed it with balena etcher successfully. Still same issue, so i tried the USB flash drive method, same with that.
As i flashed the DOM via USB, the LED on the DOM flashed green, but built in the LED stayed dark. 5 Volt on the outer Pins.

HDMI has no signal.

Hey guys!

a little update on the problem:

i got my hands on a TS 469 Pro and switched the DOM into my 669. Same problem.
So i tried switching the power supply, still the same.
Then i switched the RAM and... BOOM! ...but:

Display shows "ready for test ver 1.2.8" and Qfinder wants to initialize the NAS. Seems like it doesnt recognize the NAS as the old one, also the name showed in Qfinder is not the old one, but "TESTD2008B". Could it be because i flashed the DOM already?
I had mounted 5 HDDs with a lot of data on them. Is it possible to keep the data? I know on which HDD the system data is saved, does this help?
If i initialize the System all my setting are gone, right..?

... sooooo, i guess all my data and settings are lost..?

I would open a ticket with QNAP and see if they can recover your system. Flashing the DOM probably wiped your settings.
