| I figured the analog outputs were being pulled low somehow.
| | - what happened here? |
| | |
| I desoldered the inductors and capacitors so the analog signals weren't loading any current.

| | |
| Probing the signals showed no difference.

| I attempted to solder things back together but it ended with ripped pads. I had a webcam acting as a microscope that didn't magnify well and blocked my motion, and too large of a soldering iron tip that I couldn't position properly. I also lacked a lot of experience and didn't know what to do.
| |
| | |
| In short I managed to:
| |
| | |
| * Lose three capacitors
| |
| * Desolder two inductors
| |
| * Rip a set of pads for an inductor
| |
| * Rip a pad on one of the analog output capacitors
| |
| * Burn a lot of plastic
| |
| | |
| Not a great move on my part.
