hello bidya
the site was having some problem,so i was not able to guide you.
first you check the 300volts dc at cl6+ with respect to cl5-which is ground of power supply primary,then check300 volt at pin 1 of ica1
check 300 volt at pin 678 of icm1 if your getting this volt then your transformer is ok, if you are not getting this 300 volt then your
transformer is open ,so you check this first .take care that you dont touch the primary side when the power is pluged.
