Hypex SMPS 1200A400 powering up delay and failure

[alexIG]

Initially it was 5min delay and it became 30-45 min delay until it would not turn up at all. I suppose some caps have failed.
I was reading that people had similar problems with Hypex SMPS and in SMPS1200A700 it is typically c39, c38 caps: 220mf. In SMPS400A400 the problem was also 220mf caps. There is no schematics for 1200A400 so I wander if anybody has similar problem and figured it out what caps need to be replaced? I suspect that these should be caps that I've circled next to the transformer.

I just found another thread about delyed start of SMPS1220A700 and the problem was C38. I found C38 &C39 on my board it looks like the positions of components are identical for A400 and A700 and both caps are located next to main power supply caps.
