N0 power or lazer led lights come on on 40 Watt Module

My latest issue is everything else works as far as led lights go, and movement on a print. With no power led to module and no laser led,** It does not cut or engrave ! have checked every plug on the two boards for left and right for broken pins and connectiveness. I even have a new 40 Watt Module and new power adapter, Even the small 1.6 watt power mini light does not come on. And also my other 40 Watt Module same issue is their, All other LED on module work as they should front face and normal and precise. All lights and alarms work on housing frame.
