kung china board iyan... intermettent power issues yata iyan.
sakit yan ng mga ganyang board.. try mo tanggalin ang trimmer sa biaser/feedback circuit at palitan mo ng fixed value resistor na 1k ohm.. pag ganun pa rin ay direct xtal/crystal osciallator sa uoc iyong para sa system con side... pag ganun pa rin ay direct replace ng 2 ceramic caps na ito
