the board was dead, thank you all for the replies. its been replaced by dye, although i had to cough out £30
the problem with the slow ROF with eyes on i have just found was something else.... will copy and paste here for anyone else having this problem, it has taken my a long time to find this info.
When I'm playing with my marker at home and cover the eyes it seems to fire really slowly.
As per everyone's favourite super mod Uziel Gal
"The slow rate is due to the board registering an eye fault.
When your marker fires and the bolt retracts, the eye first looks for the chamber to be empty (bolt open and no ball); it then starts to look for a ball to enter the chamber. It will then acknowledge the presence of the ball and allow the marker to fire as soon as the trigger is pulled.
If on the other hand the eye sees that the chamber is constantly blocked, it cannot tell the differnce between the bolt being closed, or open, and whether or not there is a ball ready to fire. It assumes that the eye is faulty, and so reverts to a lower rate of fire in orderto avoid chopping.
In other words, by constantly blocking the eye with your finger, you've caused the board to think that there is an eye fault.
If you want to dry fire your marker, or just click the solenoid, turn the eyes off. If you want to see how fast your marker can really fire, then you need to get out and actually shoot paint; blocking the eyes just isn't the same as shooting paint."
