Corona V5 Xbox 360E no power.

I've bought the console from a fella, who tried to read a 16mb NAND with a 4GB R/W QSB. To make matters worse he broke a pad. It booted fine though. I fixed the pad, read the nand, written ECC, soldered the chip, put the postfix. Aaaand it got worse. The console does not even beep when I turn it on. Saw that the R4P4 is peeled. I repaired it. But it does not help... The flux is a no-clean SMD one. So it only looks bad. It's non conductive.

The PSU has a yellow light.
