Hi all,
I picked up a TP-Link Archer C3200 for cheap because it "wouldn't power on." I was (perhaps somewhat naively) hoping that it would be something as simple as a blown SMD fuse or similar that I could easily fix. However, when I opened the unit up, I found that it had suffered some sort of massive power spike (lightning strike maybe?) and had apparently burnt up a number of components near the DC input.
After cleaning up the effected area, according to the PCB labels, it seems that the missing components are two pairs of SMD ferrite beads and a small SMD capacitor. I searched for any sort of service manual or even photos of the same/similar boards for reference, but had no luck. Does anyone have any advice on how I could figure out the values of these components? Would it be that critical to find exact matches? It also seems that there is a short to ground somewhere on the board that I'll have to chase down, so hopefully it's not a complete waste of time anyway. I appreciate any input though!
I've attached a couple photos for reference.
Thanks!
