Surface Tcon Device cannot start (STATUS_DEVICE_POWER_FAILURE)
Replaced battery and screen on Surface Pro 5. After reassembling I powered on the device and started up ok, but a portion of the screen wasn’t responding. to touch. I shut it down and disassembled to check my connections but when I did I removed one of the connectors improperly. This damaged the pins slightly. I was able to gently bend them into place and when I pushed the ribbon cable into it seemed to connect in just fine. Removing the ribbon cable and inspecting the pins again looks ok to my eyes, but when I power on the device there is no backlight, the microsoft logo flashes a couple times and the display goes black. Connecting to a external display shows the device powered on just fine. I’ve checked all my other connections and they seemed fine. I’m stuck looking at the connector I damaged but it too looks like it should be working still. Anyone have a schematic or can at least tell me which ribbon cable provides power (left or right) to the display.
