RGH PLL_BYPASS Messed up

[DarthNihilus]

So, I was following Fiber's tutorial without issue until I soldered the Coolrunner to my falcon.

When I turned on with everything connected I kept getting a solid red light on the CR and my hdmi input was not detected on my tv.

As I read through the forums I suspected my wiring on the PLL_BYPASS.

After attempting to fix this, I tried the alternate PLL_BYPASS but, the SMT resistor( I believe) has now come off.

Have a look at my attached image.
The point circled in yellow is a good solder point, but the two in red rectangles are not.

What to do ?

what pic?

 

[DarthNihilus]

Just uploaded.... man you are quick.

 

[ccNick]

You have lifted the pad?

 

[DarthNihilus]

Lifted the original pad, and the resistor, but the point in yellow is still a good solder point. Would I be able to add a resistor and attach my wire still ?

 

[ccNick]

Possibly, with a wire bridge.

Do you know where the alt point is?

Also, are you sure you want to attempt this again? Should you not send this to a pro to make sure your board isn't completely killed after another bodge job?

 

[DarthNihilus]

I'll attempt this. I'm not too worried about the xbox since it's banned and I don't use it much anyways. I have another one which won't be touched.

If I solder on another alt point, won't I need to still add the other component back ?

 

[ccNick]

The resistor is needed, do you have any spares?

A through hole resistor would probably be a better option now.

 

[DarthNihilus]

I've got spares, not SMT resistors though.
What is it's value ?

I guess if its a through hole resistor, I'll solder it on and then wrap it in shrink tubing.

 

[ccNick]

You're going to need to remove the heatsink to get to this pad.

I'm at work at the minute and have no 360's here to test the resistor, you'll have to do some searching to find out it's value.

Good luck!!

the value of that resistor is 10k.

 

[DarthNihilus]

So under the heat sinks I would solder my green wire on the opposite side of the board. Can I trim the length of the green wire ?

Where in the circuit would I solder back the 10k resistor ?

 

[ccNick]

You need to bridge the remaining pad on the underside of the board and the pad under the heatsink, with the resistor inline.

 

[DarthNihilus]

Ok, so let me try to make sure I understand.

I've removed the heat sinks and see the trace. I've scraped off and can see a pad to solder on.

my circuit will look like this now.


Yellow Pad from my original diagram-> 10k Resistor -> new pad under heatsink -> Cool Runner

Two wires will be soldered to the new trace point.

 

[ccNick]

That's correct, although I would probably not solder two wires to the tiny pad.

I would solder two wires to the resistor, on the new trace point side of the resistor.

Does that make sense?

 

[DarthNihilus]

Thats what I was thinking as well. I will solder a small wire on the new pad. Run it out from under the heat sinks and then solder up the rest.

 

[ccNick]

Good luck

 

[x360ccm]

take a look here gives you a good idea of what to do.http://www.team-xecuter.com/forums/showthread.php?t=74992

i wouldnt solder 2 wires to any of them if i was you.

you damaged it just putting 1 wire to it.

 

[DarthNihilus]

Boys.
Good news.

It's working like a champ!!!

I had the same issue after I booted though.
I saw in another forum that they needed to plug the nand-x to coolrunner in when they powered. After I did that. I power cycled the xbox and now have the xell reloaded screen.

Thanks for the help!!
