Faced similar situation... It was working an hour ago and stopped turning on all of sudden... Checked power cable... Tested the cable by putting it in my cam charger... It was fine... Shaked power point as sometime it's due to loose connection... Still no fix... Finally shakes the cartidge box gently... Cleaned the printer.... Connected power cable again and this time it does turn on... What a relief.... Try it... If it works for you as well... Good Luck
