Checking the primary of an SMPS transformer with a Blue Ring Tester will show shorts in either primary or mostly secondary. Please search for Jestine Yong's guidance for use of Blue Ring Tester.

You mentioned that you checked the primary side of transformer and it showed shorted. Would that not indicate that there is a problem on the primary side? Maybe you meant to say you checked the secondary side of the transformer and it showed a short therefore you would search for a shorted component. Please clarify for a novice like me.
Really enjoy reading your articles. Learning so much. Thank you for your time & contributions.

The use of your old car mirror is another example of "nothing is wasted, everything is transformed". Greetings.
