Amiga 4000T not booting

[sniken]

this is what i think:

you can't enter either csppc or p-iv early startup because you are using a keyboard adapter with a ps/2 keyboard and not an original amiga keyboard (or?).

csppc is set to default 31khz out on the the rgb port of your amiga, caasing problems when p-iv is scan doubling to your lcd monitor. you have to set csppc not to default 31khz. hold down the esc-key (may not work because of the above).

if you can see the amiga early startup you should be able to see the others too :/

i used to have a rgb-to-scart cable, but i guess you don't have a scart input? got an a520 available? try using a rgb-to-vga (the one that came with the a1200/a4000) instead of connecting to your p-iv if the signal is indeed 31khz.

i'm afraid i do not know.

good too see you got your csppc menu up. care to share what you needed to do?

did you get any p-iv menu up as well in the end?
