Starlink router Gen2 not working

[Barabashka]

Good afternoon. I have a non-working Starlink router for repair. Problems were found with the power supply, I saw problems with 12V with an oscilloscope, replacing the capacitors helped, but the router does not work. I connect via WiFi, but it does not see the dish, 48V does not come from the router, the cable is working and another one was connected. I read the dump from NAND https://u.ua/d/6yJVm66/ , can it be damaged by voltage drops? I read this blog https://olegkutkov.me/starlink-repairs-archive/ , can the IC EN88018N be damaged? Thank you.

Hi  Barabashka,

The router firmware does not control 48V. Please check that the power supply provides this voltage.
Then check the white F1 fuse. This is the most common reason.

Hi. I checked the fuse and transistor first, they are OK. 48 is supplied to input source Q4, I loaded a 47 ohm resistor here (1 amper), 48 and 12 are OK, nothing on the fuse. Replacing TL431 did not help. But when I turn off the cable 220V , 48V appears and drops according to the discharge of the capacitance. I'm trying to figure it out further.

Please try connecting the 3.2K resistor to the output (near the PoE transformer, or to the D6 point).
The PoE controller should react to this load and activate gate of the Q4

Thank you, it works, I have 48V. I ordered RJ45 to be redone, there must be a problem somewhere in the cables. I'll write later.
