It

Since I have the same problem... In my case power led is bright. Caps lock lights about six times then it stops. Does it mean something?

Yes it means the CPU isn't started up completely. Look close at power LED the second you press power on. If the ROM are active the first instructions they give is to brighten the power LED. It should go to to bright a sex nd after power is on.

Check your CPU socket for green or if you have been using a vampire in it you may have bent them out to much. I've had to replace several 68k sockets for vampire owners lately.

Reason #69 that the Vampire folks need to have plenty of expansion slot adapters around!

I'm building several when the boards get here to sell actually.they will be under $40 shipped too.

I replaced cpu socket. At power on it goes to insert floppy screen but after  60 seconds or so it freezes. If reset then screen stays black or goes to white. If I turn power off and wait little longer like 10 minutes it boots to floppy screen and freezes again after a while.

Do you have another kick-start ROM you can try?

I am also leaning towards trying to remove every chip and clean with a toothbrush and 99% IPA. If you have a good disk washer after the chips are removed you can use it to run the board through a cycle as long as you let it sit on its side at an angle and dry out ofter for a few days.

Would you run it without any detergent?

Right, just water. If your water is hard I would be sure to use some IPA right after to get as much water out before drying. It wont hurt it, but makes cleanup harder if it puts a lot of mineral deposits on it.

That did it! I removed all socketed chips and put it in a dishwasher. Then cleaned with IPA. Also resoldered everything in CPU area. It's been up for a day running demos and stuff. No issues so far. Hopefully, it will last.

I've got several working again after a good clean like that. Oxidation causes resistance values to change, getting all off and cleaning sockets helps a lot. A more drastic measure is a complete resocket and replace all the components in the battery area.
