The LEDs are strobed by CPU.  If you can pull the CPU (some revs of the controller board have socketed CPUs), you should see the LEDs turn off.

Since all the LEDs are on, I'd say the CPU is executing bad data.  I'd try reading the EPROM.  I can't say for sure, but Google should turn up a good image to compare it to.
