Can you believe you'll get dummy IC's in the market(the one which physically resembles the original IC but vacuum inside!!). Recently I bought two parts DP704C and A6351, both are SMPS replacements and didn't work at all. Actually we could not trace what else could be the problem, replaced again with three of them and same happened. The terminals just shows the open circuit voltages. Next time got the original one and it worked well.
Sometimes I would think the fake ones beats the originals in look and feel. I'm totally confused because this will lead to wrong assumptions on what we're doing and time waste.
