Have a Hyperball that the P row of lights are brighter than all the rest. Game plays, but the P row of lightning bolts seems to also flicker in game when they should not. Traced out the circuit and verified the components i could such as resistors, diodes, and transistors. For better or worse I installed sockets for the known IC's in circuit and since it uses several of the same ones in key areas I flopped them around to see if the problem follows an ic... it does not. It does have a few of the SR type resistors in the circuit not sure out to test those. Do transistors ever test ok but turn on when they should not?
Anyone seen anything like this happen on a driver board before?
