There's been a few models I've tried repairing in the field, and it would have required a likely damaging of the end of the WiFi antenna wires (at the very least). Some will have this effectively thick copper tape that's soldered onto the end of the WiFi wires, and the glue is very aggressive.
And again, some you can peel off without too much trouble, but some not as easily. Granted the vast majority of my repairs were onsite at the customers home/business.
