I have a dt830d multimeter with it's circuit board with No.220282-B marked on it. The dc voltage segment shows 1 when a std. 1.5V supply is connected and 203 AC volts is displayed when 230AC supply segment is switched over. Please help me in identifying the defective component/s through a photograph showing the components and their values. The Model No. of the multimeter is DT830D - UNITY. Thanks and Regards.
