PS3 CECHK instant YLoD? as soon as it got power

Hello,

I've got a CECHK03 FAT PS3, with an unknow past.

The console has a weird kind of YLoD that I never encountered.

As soon as the console has power (as soon as the AC cable is plugged and the ON/OFF switch enabled), the console made 3 beep and a blinking red light forever.
It won't respond to power button, it will only beeps when we touch the eject button.

It doesn't do anything else, you can unplug then plug it back, as soon as power flow thru it, 3 beep then forever blinking.

The board is a COK-002.

It seems to not have been dismantled, the warranty sticker was off, but there was original thermal paste and every screw, no sign of any kind of repair.

I've used the syscon script to retrieve error, there was only this error for 2 times : A0801001.

Since then, unfortunately, syscon soldering point has been damaged, it's the first time I see this : the solder completely went away from the board when soldering, with no way of attaching new soldering pin even using flux and scratching some of the PCB, they are completely gone...

I've tested all the fuse, they are all good.

Does anyone ever saw this behavior on a FAT PS3 ?

Thanks everyone.
 
Have you tried testing the power supply? A faulty power supply may cause unusual behaviour.

I don't have this model of PSU as spare, I only have older from CECHC, different size, 4 pins for the 5V, and PSU for SLIM model.
I tested it, there is 5V on the 3 pin connector.
The 12v are delivered when the PSU receive the signal from the console.
I don't know how to test the 12v, I saw that you maybe bridge 2 of the 3 pins to start the PSU.
The board also do this behavior when I only connect the 5V without connecting the 12v.

The PSU is very clean inside, no capacitor leaked or damaged, no burn, nothing, this console seems to have be sligthy used, I didn't checked the original hard drive running time.
