NOTE: If FET is found defective, check and replace all the
components [marked here], before replacing it with a new one. Check all the solder terminals at power
supply section circuit, for any loose soldering terminals. It is advised to re-solder all the suspected
solder terminals by applying a little more solder, without making any solder
bridge short in between adjacent solder terminals. Replace (Q501 – KTC3198 – Buffer) too, even if it shows no defect
on testing.
