I'm trying to rig up a VGA output (sync-on-green) by soldering the plug directly to the motherboard. I don't have a spare AVIP connector sitting around, so I decided to attack the motherboard from underneath and solder directly to the appropriate pins.
Only problem is, it doesn't work. I can't find any two places on the internet that show the same pinouts for the AVIP connector, so I don't really know where I'm soldering to I suppose. The monitor keeps insisting that it isn't connected to anything (the old "check signal cable" message). Am I missing something obvious?
HP D2818A monitor (also tried Dell M770)
In short, is there a tutorial showing what points on the motherboard correspond to certain VGA lines?
