Right, so I got my cable and plugged it into my Xbox, and I'm having problems. One is a little problem, one is a Biggie...
Small problem: The Xbox is modified, as I mentioned above, and the image is unstable on the mod bootscreen in 480p, cutting in and out. When I change the settings in the mod menu to display in 1080i, the image is absolutely perfect, it looks great and stable and all that. So I get that the mod chip may not play nicely with the cable. However, it seems that whenever I reboot the system it always reverts back to the lower resolution automatically, so I don't know if there is anything I can do to fix this permanently. All 480p and 480i output from this system is grainy and crappy.
Big problem: Banding and noisy image playing real games on the system. I did not notice any rainbow banding at all in the image over composite, but now I'm using this cable I can see significant banding distorting the colours in my picture, plus huge amounts of general noise in the image. This does not appear on the mod menus at all, but as soon as I'm getting the image straight out the Xbox, it looks like crap, worse than the composite image I was looking at before.
Questions... I know that the cable is fine because I tried it with my other unmodified Xbox, and the picture is a definite improvement over composite, very crisp and clean (even though the PAL Xbox can only show 480p unmodified, it still looks pretty good). So:
1. Is the mod chip somehow interfering in some way with the communication between the Xbox and the cable, causing the banding and noise?
2. Is this Xbox just screwed? I already replaced 3 leaking caps in this one. Did I do a bad job, and the replacement caps and repair process have further worsened the condition, OR did I not go far enough and should go in and replace all the caps?
3. Would bad caps give an image over composite that looks ok (for composite), but a very bad image over component? Like wouldn't it be both bad rather than either/or?
I am really struggling to figure out what to do here... At least the silver lining is that I'm getting a good picture out of ONE of my Xboxes, but I was really hoping to get the best possible picture out of my modified one and take advantage of up to potentially 720p and 1080i.
A little more help, anyone, please!
