The last week i have repaired a power supply ES281CMB. i dont have the schematics but my problem was a open resistor located under the key program-normal-set up. I replaced the resistor with a 1.8 Mohm 1 W and the power supply now working well.

sorry if this is not the solution for your problem

best regards,
Franco
