PS3 Is the mosfets pwm controller damaged in my ps3?

In my ps3 slim 3004a, after clicking the start button the console makes a "beep" and lights up a green diode, but after a few seconds everything goes out. The sequence repeats endlessly.
Here is the reading from syscon:

When I started measuring the motherboard I noticed that the resistance between the gate and the source in the two mosfets on the main power supply line of the cell processor is from 3 to 17 ohms. When I try to turn on the console there is no voltage there either. After unsoldering the mosfets the low resistance did not go away, so following this path I reached their 6610cbz pwm controller. After unsoldering it the low resistance went away. Is it the culprit or something else?
 
I know beginning from 25xx series onwards, Sony did use full tantalums on the CELL/RSX. 3003 from the web indicates severe CELL power issue. You might want to try replace those caps with new ones. Before that, you can check for shorts on the tantalums first.

My CECHA's blu ray drive circuit didn't work previously due to bad@shorted 25v 47uf tantalum cap.
