I am glad that you got a replacement for the one that was defective and I am with you about trying to fix it
But I would highly recommend that you recap this board before you really start using the replacement one because they have off brand capacitors and there are know issues with quality of them

If you want a list of good quality brands and what series to use for this switching power supply just post a picture of the capacitors that are in this switching power supply
