I concur this does not match the A1465 board in some areas. The Airport / Bluetooth connectors are in a different spot and the heatsink is different. Perhaps some photos from another board were used in a few places. The rest appears to be the same, so far.
Replaced this because the power button was slightly depressed, "spongy", required a lot of force to activate. Proximity sensor was also flaky. Since the repair I have the following issues:
1) Power button is still spongy, no audible/tactile "click" sound/sensation. Suspect the cable was not the cause of the original physical button issue (as others had suggested)
QUESTION: What should I look at next for the physical button issue? The bracket that holds the power button/cable against the outer casing seemed fine physically, but maybe not?
2) Power button is hyper sensitive, acts as if it's "stuck". When pressed once it acts as if it's held down. Tapping it very lightly will sometimes initiate a single press (i.e. lock the phone) 95% of the time it acts like it's held down (i.e. nothing happen then seconds later it shows the "slide to power off" screen).
QUESTION: Does this sound like a flaky connection issue, bad/damaged cable? What should I investigate?
