sukatin mo screen voltage mo or g2 sa c board nya,dapat nasa 500-600v cya,may variable resistor sa c board kulay itim at ay nakaseries na resistor from 1000v terminal,680k,tingnan mo baka changes value na,if buo resistor,try mo adjust yung vr na yan,if ayaw,palitan mo narin vr,sa nanginginig ang picture,kung sa itaas at ilalim lang nanginginig,palitan mo yung capacitor na 47/50v sa may pin-out transistor,pero kung pangkalahatn nanginginig,posible flyback problem mo may arching na sa loob...
