4. Let the set age for 30 minutes.
5. Reset the Error Log.
IMPORTANT
After replacing the defective component, make sure to add a check mark next to the module label.
Component level repair must only be conducted if the workshop can perform a Hi-pot or insulation test.
If the power board is not fixed even after changing the resistors, do not attempt any other parts replacement. Just replace the entire PSU board. Description Models Part number G5AW-Static Converter (TV) KDL-46NX72x, HX82x FX0028511 G5D-Static Converter (TV) KDL-46EX72x FX0009411
