Laser tube problem or Laser powersupply problem 

A simple way to test if he power supply is working is to use a neon screwdriver on the insulation - yes that's right on the insulation of the HT lead - it will light up if there is HT there - DO NOT USE ON THE BEAR LEAD.

Hi Melody, That resistor, what power and value is that? What is the power of this Reci-tube in this machine..

Thank you

My machine has no sign of electrical connection at all. when i click on the test bottom, there is no light at all. Any idea? is there any fuse? FYI, I use 110V power cable and the machine has the power transformer to 220V.

My machine is firing a weak violet pink beam bot not burning at the end of prism

my machine stopped working I thought it was the tube e bought three more the problem is that if you power but work just turn the tube in the beginning but the nape laser works, energy can be a problem?

You have the test with the IN connected to 5V using terminals 5 to 6 connected but my WEIKE power supply has no test button. Should I put a switch shorting TL and WP to G
