Installed my chip.. triple reboot frag w/ chip enabled..

[BCoon]

And it frags when it's disabled.. but I'm 95% sure that's because I didn't have the video cable plugged in.

Where should I start looking for problems? To save time in the future, do I need to have the dvd/hard drive plugged in to check it while avoiding it fragging because of this?

Pretty pissed about this problem..

How/why is a triple reboot frag diff. from a reg one?

 

[BCoon]

Nevermind.. took it back apart and discovered that even tough the solders looked good enough, when I slid the chip down on the pins, one of them were sliding down also; so the pin wasn't going up into the chip, nor was the solder joint connected. So, all is good now!

Let's see if I can mess it up w/ flashing now!

Grr i get this when I have chip enabled. When it's off i get normal boot.

I'm using wire install.
I fear some of wires on the actually PCB are being shorted cos the surface has been exposed due to scratching.

I've done everything, tried installing it on the top and bottom, and even put the pin header in. (I removed the solder from the holes).

All produced the same thing, reset x3 then FRAG..

I'm an experienced solderer and have done many consoles before. I know often it's just a poor solder job, but this problem is consistant no matter how many times i resolder.

Could it be a problem with my V1.0 XBOX? It is one of the earliests.

P.S. I am trying to repair this for a friend.

Sounds like a bad chip if you're positive everything else is soldered correctly.

If you could do it accurately enough, try putting some liquid electric tape over the areas that you think you might be shorting against your wire install.

not a bad chip bad install

 

[Osirls]

Definitely not a bad chip, i tried it in my own console, works fine.

It can't be a bad install, i've tried installing it every means possible, over and over...
I chip PS2s, which is a lot more difficult.

 

[Osirls]

Ok well i thought i found out what it was..
The d0 point on the board that you solder too had become detached, and i found that the console would reset 3x and then frag without the chip in in this state.

So i put a wire from the ends of the d0 tracks and it booted up normally again.
So then i install the chip again (from scratch not just plugging it in) and i attach the grey d0 wire to the new wire that i just soldered to the board.
This leaves me in the same situation, normal boot with chip disabled, 3x reset and then frag with chip enabled. This is leaving me baffled..

 

[Osirls]

Bloody inexplicable!
I soldered to the alternate d0, same results.

A D0 point will not cause a FRAG. Since you are having problems with the chip enabled the D0 point is fine. Check the LPC bus with a multimeter. If that checks out, check the switches with a multimeter. Links for both tests are in my sig.

OK part 1,
All Voltages are fine except pin 1 i get 1.65v instead of what the site says, 0.2V. It also suggests it should be 3.3V, little confusing..
The ground i get 0.004V which is ok i'm assuming.

 

[Osirls]

The resistance measuring on that guy is incredibly confusing..
The diagram being low resolution is bad enough, but he is confusing in what he mentions about his conversion table..

Is it that the points on the table go together?
i.e. left collumn is LPC points, right is the hole points?
Is it that the right is the picture's LPC labels, and the left shows what they should be?

So confusing, either of these i tried i've gotten some high resistances..
He also doesn't mention you need to scratch of the coating for the points on the board, very important..

 

[Osirls]

ARGH!
Ok i tried my X3 in this V1.0 (where i had been using an X2.6) and it works. Explain that....
The X2.6 works in my own V1.1 xbox.

 

[Fantmx]

Sounds to me like there is a problem with the switches or the wires going to them. Did you run them under the controller port in the non working box and accidentally pinch them so they are shorting out now?

 

[Osirls]

Nope, i dont have it inserted under the controller ports yet, would have to take it out each time etc.
I've checked the cables are inserted properly etc.

It is so bizzare that it works normally in my V1.1 fine, but refuses to in the V1.0..
I'm going to try flashing the chip with latest bios, i don't think itll work, it's not even logical, but i'm just running out of ideas now.

 

[Osirls]

Woot, for some reason that worked.
What a waste of time eh.. At least it working now.
Just gotta replace his hd and he'll be a happy dude.
