== Probing desoldered signals again == After a long hiatus I took a look at the signals again. At this point I don't see any signals at all, even after attempting to patch drivers to output test signals. Still my monitor detects Linux. Interestingly my USB to VGA setup detects both BIOS and Linux. Maybe the 'Input not supported' is related to HSYNC/VSYNC polarity? I believe the capacitors I desoldered were connected between analog ground and the red/green/blue signals. I'd imagine they're very low values around 10pF or something. Soldering the inductors back seems like the next step so I can hopefully try to reproduce the Alpine Linux login prompt. I did probe the area with a multimeter. I think the middle ESD diode has failed. Could that be pulling things low?
