PS3 YLOD

I am seeing the guide which unfortunately is in German. I translated it with google but it still does not make much sense. How come the arrows are pointing to the motherboard? that means that I have to solder the new rsx before testing it? in that case I might as well assemble the console. I wish to test the rsx before soldering.

ok you told me to follow the conductor to the pad. sorry my bad

but still in the picture there are arrows which are pointing to places on the motherboard where there are no contacts eg:1,2,5

The numbers shown in the picture are different powersupplys of the RSX, measure them against ground. If you have 0,5 ohms at point 1 and/or 0-2 ohms at the other points your RSX is defect. If your values are higher, it not means that the RSX is OK.

yes ok that part I understood. but pomts 1,2 and 5 are pointing to areas where there are no contacts.

Is there a way to get the pinouts of the GPU to check? eg G7 to ground, AH12 to gnd and so on?

The Arrows are pointing to a coductor, where many contacts are connected to. Because of this you can use any of the connected contacts and not only one. If I put the arrow to exactly one contact, someone could think he can only use THIS contact. And, of course, you can remove the varnisch from the copper

is it possible to have the pinout numbers on the rsx which ones to test for ohmage?

Takeshi · 05. Mai 2013, 01:15:07

These are very much. And quickly I don't have the pin-numbers.

here are the chip pinouts

Now on this page there is also an image with all power supplies.

Thanks Takeshi very kind and informative of you. Where I should measure and what (approximate) values should I expect?

Takeshi · 06. Mai 2013, 19:38:21

You should measure like before: Between ground and power supply. And like before, I can't call you the values, because they deversify very much. The resistance of the first one (red, main supply) is very low, ~0,5Ω to 3Ω, but this depends on the multimeter. The other are higher. If one of them is broken, the value is mostly unter 2Ω. But what's the "normal" value, I can't say.

rod905 · 06. Mai 2013, 20:06:09

eh ok, so you should check the 8 colours to grnd. I presume that I don't have to check every single one because they are connected in parallel right? the value should be at least 2ohms+multimeter/probes resistance to be good.

Right

Choose one of them, that's enough.

At some pads I have 200kΩ (i think it was yellow), but with another multimeter it could be 1kΩ or 20MΩ. The lowest value was 12Ω I think, the next ~100Ω and the other 1kΩ or more.
But until now, every broken RSX had a resistance under 2Ω.

Hi Takeshi, I received the chip today and tested pinouts AD23-AD24 and found them to be 0 ohms. I guess I would be right to say that there is no way this chip would work right?I already contacted the seller to advise him of that.

Takeshi · 07. Mai 2013, 20:18:40

I had one, there was the resistance ~0,1Ω (main suplly, red) and I only mounted the RSX to get the PS3 complete and the PS3 worked. I don't know why, because 0,1Ω at 1,2V means 12A (-> 14,W) for nothing. I have to mention, it was only one RSX like that which worked.

You could test it, but the problem ist, if it doesn't work, you don't know why. But I think it won't work.
