    Default DT-30 doing weird scanning

    Hey guys, i was using my laser just fine, and one day it suddenly started doing these weird images, i bought the DT-30 used, installed it, used it for about half a year (only 5hs a week), i leaved the laser without use for about like 3 months and when i want to turn it on, i put quickshow and some beams and i start watching lines instead of dots, i mean, you can see the dots but there's a line through them, and when i do the test pattern here's what i get, i don't know what it can be because i forgot about everything i knew about lasers by no using it for about half a year

    Check your cable, especially in reference to pin 25. It looks like it could be a grounding issue.
