I would start by changing the caps if you see physical leaking.

The best thing to do is use an ESR meter and check all the caps in the
power supply. Most of the time when any electronic parts fail including
caps, there is no visible indication.


Yes. I replace 2 caps today and so far so good.

Thanks all for your suggestions.
