Hi, so I've got a 79001 board that I've trimmed with the standard trim. Everything was working fine and I could get composite video out. Last night I tried wiring VGA up and got it to display picture but it was yellowish. I think I could fix this in the ps2 settings perhaps.
But my soldering for my H/V sync cables wasn't the best and one of them came off overnight. I tried reattaching in a slightly different spot this morning but since I have done that I have not been able to boot the ps2 at all.
I tried unsoldering every connection from the board and then reconnecting just the power and a cable connected to the reset pin that I short to ground to boot but I cannot get it to boot now at all. I've got the appropriate voltage going in (~8.4V).
The first 3 images are my wiring for my power. The 4th is the area that I tried wiring H/V sync to. The last picture is that same area but with some notes: the red points to where I originally had H/V sync cables connected and it worked.
The yellow is where I tried to relocate the H sync cable too
And I noticed that I had accidentally spilled some globs of solder covering the capacitors marked in white. I had tried booting while these were covered and then noticed afterwords, removed the solder, and tried again.
Any tips for troubleshooting this?
