I have just picked up a LW3. It had a power supply that was in need of repair and it did not start when I got it home. I replaced the power supply board with a working xpin board I had as spare and replace burnt connectors. When I turned the machine on it tripped the circuit breaker. I reset the circuit breaker and turned the LW3 machine back on and it worked. The next day I went through the same process with the same results.
Is this something to worry about and what should I be looking at. I did notice at times the bottom of the DMD did look a bit strange so not sure if there is something going on with the DMD / high voltage or if that was a seperate issue. I will post a photo of the DMD shortly.
