My Countax Tractor Will not start no power?

I have a countax seat down lawnmower and I have no power to the dash when i turn the key on. When i go and start there is nothing. It appears to have no power. The battery is ok and all the fuses are ok. I have replaced the keyswitch but still the same. I think it is the pcb board on the dash but this is £100 to buy. I have checked all switches are they are okay. I am wondering if there are any more fuses on the tractor.
