Hi Anand, With the machine off, and programs closed click the following at the desktop My computer/C:driver or local disk C/program files/melco embroidery systems/amaya Locate Jobs folder (don't open but right click it and delete & do the same with the machine folder also). Make sure settings by color in the software is not selected. Reseat cables at the cpu, reseat the keypad cable and tap all of the buttons in case one is sticking. Open the thread feed assy covers behind the head and below the thread tree) and inspect and clean & reseat the thread feed pcb connections also do the same at the colour change card on the upper left side of the needle case.
