Synology DS218+ no power

[H1ghl4nd3r]

This has same issue as the ds718+ no power and greened light stays on with new power supply
I'm going to change the 2032 cmos and see if this does anything, as the visual inspection did not pick up any holes in this chips on this motherboard.

There is a suspect place I noticed on pic 3, it looks out of place
Edit: Also found this on the U3 chip pic 4 and used microscope on pic 5



There are quite a few posts on this model again doing the same no power or it shuts down overnight, most seem to be the power supply but as mentioned this is a new 1.

It looks like someone has had some hot air to that connector, maybe in an attempt to remove it.
Is that mark still there after cleaning it with IPA?

I didn't clean it or the board as this looks a mess you can see someone has taken the power supply off and resoldered on the board

I'm probably better off using the board for parts and selling the case off etc, then what's left of motherboard I can use for micro soldering testing

what a mess - is that a double usb3 socket they pulled off?

Yes, with an Ethernet port as well

Also just noticed that pic 3 (circled in red) shows a SK34C chip that I needed for the 1520+ I posted a few months ago in this section, only problem is I’m not sure if I trust them and my replacement chips are in the uk and on way to me with the replacement switch for the 415+ so hopefully be able to sort them this week
