My 415+ had the famous C2000 issue where the timing signal wouldn’t be sufficiently pulled down/up. This lead to freezes and ultimately to a non-booting device. And that happened like 3 months out of warranty. The only “support” Synology offered was in helping me selecting a new device to buy.

And they clearly knew how to fix it at this point as the support in other countries DID fix people’s devices. Luckily, the Internet did its thing and I was able to solder in the missing resistor myself.

But that was the moment where I’ve decided that the next device won’t be a Synology again.

Fyi it's not a missing resistor but a silicon defect in the Intel chip where a low-side mosfet on a clock line wears out after a certain number of boot cycles, causing the system to fail POST.

It is an easy fix (I had to do it too) but I agree Synology's poor support makes this the last of their products I'll use.

Mine lasted a good 7y+ before it showed the yellow light of death. I also managed to fix it with the resistor soldering =)
