Could be caused by moisture build up. I switched out my Blinder System because i was tired of it screwing up because of the moisture build up they seem to have. I have read others have had the same problem. I don't like the replaceable heads becasue they will leak. I purcashed the LaserMask which is sealed to the max and have had no problems since.
Also If you use a little rubbing compond once in a while on the heads they will stay like new. I did this on the Blinder Heads and they never needed replacing. When the Blinder builds up moisture it will start falsing and sometimes it would just stay on jamming untill you unpluged the correct head that had the moisture which you could actually see sometimes. Take it apart and dry it out and the problem would go away untill next time.
Also while apart i noticed the board was starting to look weathered which I feel would be bad in the future. The Blinder did save me but after using the LaserMask I beleive it is more sensitive for sure and seems to work as good or better than Blinder. I am not a tester but just a end user with this problem using a Blinder M25.
