I'm assuming you've already done this but just in case; go back over every connector very carefully and inspect that they are installed in the proper place and that nothing is off by a pin. If that doesn't fix it see the WPC95 sections here: http://techniek.flipperwinkel.nl/wpc/index3.htm#poweron that relate to the LED states, sounds, etc. for the CPU, A/V and Driver boards. You may also want to try to start it up with the A/V board disconnected since you know you had it incorrectly connected before.
