Red light on psu after soldering

[morinzo]

This is the point that martin was telling you to check

That point doesn't even need to be soldered for Rjtag, its only required for RGH

 

[benjamin94]

Thanks man, so check it with a multimeter now? Also if i just desolder it from there it will work again or is the whole stby_clk required for it to boot?

 

[Martin C]

Huh i dont get it, i follewed this tutorial: http://www.youtube.com/watch?v=VtxJd5FLd5s

And he also solders the end of the qsb to that point.

You solder it if you're competent. Either way you don't need it.

 

[morinzo]

Think he wanted you to check the resistor and see what it reads to see if you damaged it.

 

[benjamin94]

Ok my neighbour is at work now, i think im going to buy a multimeter then.

 

[morinzo]

If the resistor isn't bad then I wouldn't mess with that point.

 

[benjamin94]

I bought an Skandia multimeter it cost me 30 Euro, could anyone show me which points i have to touch?

 

[benjamin94]

I touch both pins of the multimeter to both ends of the resistor right above the red box.

My multimeter is on 2k ohm setting and its reading .034 to .036

 

[benjamin94]

Wow i did it wrong:

Just check the two red points for contuinity. You should get a beep if your multimeter support this. If not set it to 200 Ohms and you should get 0 Ohms.

---------------------------

I did the above and it beebed indeed, and it read 0 ohms. So this is good right?​

I also did this one: http://team-xecuter.com/forums/showthread.php?t=84475&p=572502&viewfull=1#post572502

And its exactly like Martin is describing.

 

[Martin C]

so if this checks out, you're shorting something else. So use your meter and check resistance between 5v and GND on the board. J1D2.6 would be a good 5v source to use.

 

[benjamin94]

Do i need to connect the power cable, can i use the videoport shield as a GND, what does my multimeter needs to be at?

 

[Taijigamer2]

Xbox needs to be plugged in but not on to give u standby voltage. Any port shields work fine as GND, this is why blck wire is soldered to av port in Rjtag. Your looking for 5v so pick the V setting on multimeter that u think is appropriate. Good luck.

Thanks man i did it here some photo's:

What to do now?

 

[Martin C]

Did you really need to take 10 pictures of you holding a meter?

If you're still getting 0x0000000 then CLK is the issue.

 

[benjamin94]

I know i took just photo's with my mobile and i was looking at the meter and just pressed like 10 times the shutter button and uploaded them all but now jrunner is still giving me 0x00000000 so what should i do?

 

[benjamin94]

I recorded a video, please take a look at the end on the r-jtag board the red LED turns off and then also the psu is going to RED LED.

It's powering on, so it's not STBY_CLK. The 0x000000 error is likely to be a connection issue on one of your NAND points.

Get a meter and check all points as per my NAND-x troubleshooting guide.

 

[benjamin94]

I followed your troubleshooting guide these are the results with the multimeter at 2V


1: .059
2: .437
3: .059
4: .437 v and .680 ohms
5: 0.058
6: .030

I dont think these results are suppose to be this way right?

 

[Martin C]

Nope - your NAND looks corrupted in that case. Follow the link in that same sticky in relation to the bad flash recovery method.
