Am working on a sharp mx 4100N only the power on and off button's light comes up.The machine doesnt warm up or initializes. It goes cold when switched on.Does anyone know any possible cause and solution.
Thanx

so no display ?
first reseat the memory modules & connectors in mfp board and see if this persists.

then try to boot it up by removing memory modules , hdd, pcl with right hand side door and front door and front finisher door open if there is a finisher .

if you can boot it up without either of them with an error; one of them is faulty.

most of the time its one of them. If no good you have to check ac pwb & dc pwb fuses and voltages. Good luck !
