I replaced the FPC connector for the display on my Nintendo Switch. I was having an issue where the display would only turn on when the charger was plugged in. I inspected the FPC connector and noticed a couple of bent pins, so I replaced it.
After removing the original connector, I tested the board without the FPC connector installed, and it powered on perfectly fine. However, once I reinstalled the new connector, I got no response.
To troubleshoot further, I removed the connector again to see if it would power on without it, but this time I got nothing.
I double-checked each pin to make sure they were properly soldered and making contact. Currently, I’m getting no response at all. I checked with my tester and I’m getting 14.9V, and the current fluctuates between 0.18A and 0.2A.
