    Quadra 840AV no video or chime

    Yep, looks like it, there's liquid and corrosion by all the capacitors. I just washed the board after removing all the RAM, VRAM, etc... and it looks like the liquid is gone, though there is noticeable corrosion on some traces, vias, and components. I'll replace all of them once it's done...
