Amiga 1000 black screen

Any click from the floppy drive?  Anything on the composite output?

I noticed you had another thread in a different forum, someone was suggesting test the voltages from the PSU, did you ever confirm that?

I'd suspect the daughterboard too, but aside from swapping with another not sure what the process is to test it.  Clean connectors and reseat?

If you run completely out of other ideas, you could always try baking the board in the oven to reflow all the solder points.  :lol:

(yes, I know this is pretty much a last-ditch option, haha)
