In the Hunt pcb no sprites

Oh! Look for obvious faults on the PCB then. The first four pins (two on each side) are for ground, the next four for 5V, next two after that for -5V and last two before the notch for 12V. Look for the first components that they go to. There's a short somewhere in there, that's why the PSU is clicking.

thanks one problem solved by cleaning the contacts with alcohol but created another problem

Now the directional controls are messed up. can only move backwards or upwards .. WTF no matter which controller I use on the supergun. How could I solve this prob?

Edit: it's now back working like a charm... I don't get it sometimes but I got in the Service menu by enabling DIP Switch "SW1 #8 ON" and tested the I/O there. Got feedback from all directilons. booted up the game still direction R was not working. Tested Player 2 controlls -> working. Switched back to Player 1 by restarting the board and it works now!!

Thanks guys! That solution works for my blade master pcb. I remember me to be read this thread a while ago, and when I saw the error I instantly tried to clean the J3 jumper.
