That looks like a very useful list. I happen to have a Dell 4:3 lcd here. Not on the list, but I'll give it a try. Thanks

Hmm, are these open source? I find it daunting to order from the states, with exchange, duty, shipping. Before you know it, I've spent $100 on an adapter.

Hitting the thrift stores tomorrow, maybe a multi-sync monitor is what I need. And, yes, it is the on-board video.

Was that software specific to your graphics card?

Is there a combination of DIP switch settings that will work? Tearing my hair out here. I've tried with a couple of different LCDs. Sometimes I get no image at all.

That sounds like a logical place to start, thank you.

Yes, those are notably crusty, and closest to the worst of the capacitor leakage. And thank you bibilit for your response and those forum links. I guess I'm going to be shelling out for a hot air station.

Ya, hi, aside from some light toothbrush scrubbing with IPA on visible areas, I did not wash the board. There was electrolyte juice everywhere, and I did not touch anything hidden under ICs, so maybe that's a thing to look at, thanks.

History, symptoms: Came to me with leaky caps on the logic board. Replaced surface caps with tantalums, and repaired known bad traces. The computer bongs on power up along with hard disk and floppy activity, but usually no video. Occasionally I will get a screen like the one shown...
