i have a blinder m20 set up in my work van and a couple of days ago the alert went off and i wasn't being lasered. it stayed on and never went off. I've tried switching it on and off but it just stays on.
after tested the heads i've found 1 head is not firing so i guess from reading other threads i need a replacement. i managed to read the #s on the back with a mirror even though the heads are upside down in my grill.
it reads as follows: 5E 7.25.04 HP J9
does anyone have a spare head with this version or can i buy 1 from the blinder guy?
