Hello,While Working in the machine, I noticed that the laser fluid changed to pink as if the laser was already dead, I changed to a new laser tub but the problem continued, then, I thought it was the power supply but after changed it the probem continued. Therefore the problem is something else but I have no idea! Can someone help me out? Someone can give me an online support, willing to pay of course. Before this happened sparks were coming out from the power supply cable that connects to the laser tube.
