well there is only 8 caps to change on there so it wouldn't be a ton.

couple things to try first though.

1. double check your monitor is working, those are dying from bad caps now too,  Or  check your DB15 to vga adaptor switches,  make sure they are set for 512 x 384 or 640 x 480

2. pop out vram simms and pop them back in.

3. try to see if you get video with a nubus video card.

4. Check the pram battery voltage, might be one of those macs that get no video when pram battery is flat. -- i'm not 100% sure on this.

and if you still want a re-cap just pm me.
