Hello guys. Quite a while ago i messed up the trigger mod, it shorted and since then my umd drive stopped working. I have been trying hard to fix it and looks like i finnaly found the problem. The laser cannot focus. It lights up, the motor spins but the laser head keeps on going up and down and the umd doesnt load. I tried cleaning the laser numerous times, and today i even took apart the umd drive completly and reasambled it but it didnt fix the problem. Any suggestions?
