Yes, you are right Albert! Some efforts do go in vain a few times in our quest to find the root causes! It is a byproduct! Many thanks for your expert comments!

Thank you, Engineer Parasuraman. Its wrong to work while you feel really tired. Fatigue brings about lack of efficiency and forgetfulness, and momentarily your memory may go blank and that may leave one in a staring mood, which may also make someone to give a completely unrelated answer to a question asked. Its not because of st+++++ty. Exhaustion may well cause the kind of desparation that led you to replace the 817 opto and TL431 though they had passed the test. One Yogesh oftenly warns us to stop working until another day when the going is tough.

Another very interesting study on fixing those difficult defective smps unit cases. This time one that also made you replace some good parts invain which I take it you kept for future repairs afterwards.
