FAN flow corrosion.
Int. print on PCB connector.
Power side: 270k - bad, 51k - ok with corrosion, MOSFET over hearting, - replaced the new
IPW60R045CP -4.
CPU side: 470k (was 474k), int. print.
Used the new silicone paste for PFC and output voltage side PS
Wile test green and red LEDs flash shortly 10-20s
after this green stay on. Tested on real 230VAC after safe testing 
with isolated 230VAC input.
