Plug a monitor (like C= 1084s) into the 23 pin video port and you'll see if the motherboard GFX are working.
If it is, and the PIV shows nothing, then check the video slot looms. From memory, on the A2000 the video slot is not inline with the Zorro slots, so you have to break the front edge connector out of the PIV and plug it seperately into the video slot using looms.
