Duox2 On 1.6
« on: March 30, 2005, 09:08:00 PM »

I am currently working on a 1.6 that had a lifted trace.
the lifted trace involved lad2 on pin 8.  The trace was lifted while an LPC rebuild was being extracted.

Anyway, I found the sources of the trace and soldered wire into that and connected it to  pin 8.

After finishing the installation of the DuoX2 white, I booted the xbox.
With the chip off - the normal bootup occurs but with error 5 (HD is unlocked) - which is expected

However, with the chip enabled, there is no video/audio.
The eject panel stays a steady green for about 10 seconds and then turns a steady orange.
The led on the DuoX2 is also flashing red.

I searched for an explanation for eject led flashes, but the tut has been taken out of the pinned topics (tut by twistedpenguin, i believe)

What does the steady orange led mean?

i've heard that you have to have the standard av cables,.. so if your using component or s-video try switching out

Something is still wrong with the board. look for more evidence of damage. the eject light should not be solid orange.

also double check to see if you didn't mis-connect one of the LAD lines (on my first 1.6 rebuild got them connected to the header right but connected opposite end of LAD0 to the wrong via)

I decided to undo almost all of the rebuild wires to get a better look at the LPC.
I'm assuming the problem lies somewhere in there because there is video/audio when booting with the chip enabled.

At first I thought I might have damaged the MCPX chip because one of the sources of the broken trace lies directly beneath the chip.  It's not damaged because there is video with the chip off, right?

Anyway, here's a pic of the LPC on the bottom the mobo.
As you can see on the top portion of the picture, I chose not to repair the trace directly to the source between the LPC pins because it was harder to solder into.
Instead I followed the trace a bit farther and chose a spot to the right of the LPC.
Is this OK?

I'll redo the LPC once again and see if this has remedied the problem.

Thanks!

The way you have repaired the trace is fine it will work that way.
I am confused a bit because to start you said

Then you said

Sorry for the confusion.
I meant that there is video when the chip is off.
But when on, no video

Anyway, here is the lpc rebuild

The only thing I can see is pin 10 looks like the the LPC through hole connection is damaged. the metal ring does not appear to be a complete ring (it may be the photo)
Check the continuity through to the top side. Its probably ok as the pin is through it and the ring will be still correct at the top I think.

yeah, it's just the picture, but I'll check with a multimeter just in case.

good news and bad news:

Bad news: no video/sound and frag red/green with chip off

Good news : no more steady orange, but now frags green red
                    still no video/sound with chip on

Just checked the LPC with the multimeter on top of the DuoX2 chip

Pin 10 is OK - it's getting 3.3v

Pin 8 however is getting 5v.
Shouldn't it only have 3.3v?

Edit:
I took the chip off and decided to test for continuity using the pinheaders.
Now pin 3 and 5 are not getting the 3.3v

With power to the board OFF and the PSU unplugged measure the folowing:
(your rebuild looks OK on the surface at least.)

Resistance from pin 15 to:
1,3,7,8,9,10,11
and from pin 6 to:
2,5,8

Post the resistance results here.

here are my results:

15 --> 1 = 1
          3 = 1
          7 = 110
          8 = 190
          9 = 11
          10 = 1
          11 = 1

6 --> 2 = 104
         5 = 1
         8 = 12

I'm also getting some fluctuations initially with pin 6 --> 5  then it drops to 1
is this normal?

I took out the mobo and tested for continuity under the mobo and i get different readings.

15 --> 1 = 1
15 --> 3 = 1
15 --> 7 = 1
15 --> 8 = 1
15 --> 9 = 1.5
15--> 10 = 1 (getting initial reading of 150-160, then goes to 1)
15--> 11 = 1  (getting initial reading of 140-190, then goes to 1)

6--> 2 = 153
6--> 5 = 1 (getting a reading of 120-150, then goes back to 1)
6 ---> 8 fluctuates (sometimes it says a number then goes back to 1, sometimes it reads 1.5)
