Default Component id asus ac3100 rt-ac88u

Have this router that was damaged by lighting and it appears to have come from the modem through the WAN port.

I have 1 blown on the top and 1 on the bottom. Im guessing they are all the same values. Do you think that's a safe assumption? What type of SMDs are those 2 sets of SMDs next to each other? I can see arching and they all test 0L.

Thanks for any help

ceramic capacitors.
probably not the *real* issue, if that happened then you need to check the transformer windings and whatever connects to the other side of it!

2 of the transformers have open windings. I did check all the filters connected to the transformers and they are ok. After the filters they connect to either a Broadcom BGA or a Realtek IC.

The caps measure 1080 pF.

The 2 transformers are labeled
1642
HN18101DG

1644
HN8011VG

I cant find any spec sheets. All I have been able to figure out is its a Mingtek product but their site is worthless. I did find one on alibaba but the first number (1644) was different and they were like $20 each. Worldway seems to have some but their MOQ is like 1k-2k

Any suggestions for comparable products?
