Well, we all do stupid things. And I've done a stupid thing. I decided to wash my LC III logicboard, nothing wrong with that. Once it was dry, I reassembled my LC III, put the VRAM, RAM, ROM ICs and PRAM back on the logicboard. Booted, and I got no chime and no video. I could smell something - yes, I had put the ROM ICs in the wrong way. The sockets are 42 pin, the ICs are 40 pin. The ROM ICs were running RED HOT. So I put them back right, and I still get no video, no chime. I have tried all the known troubleshooting methods, and it's still the same. So it seems I have fried these ICs, and I might have fried part of the board...who knows. Either way, that was very stupid and I should have checked the exact position of those ICs before removing them. D'OH. xx( xx( xx(
