I have an NTSC born 1.1 box that I already properly installed four new RAM chips with. Don't worry I've done it before I know what I'm doing in the console memory department. Unfortunately I did not have the brains to address these problems beforehand.
The board when no D drive or HDD is plugged in plays the boot animation! With a solid green LED, and never loading the dash of course. So I can't really do the chip by chip black screen boot test for those of you who know of the RAM upgrade procedures. If you don't just look up the Original Xbox RAM upgrade tutorial by Floydzabarber on YouTube and watch around the middle of the video for the first chip test example.
That isn't a huge deal, that prevents me from doing the chip test but you don't need it, it is very helpful though. The real problem is when I connect the D drive and HDD, it does the chip test no drive boot mode! So I can't run anything off the optical or HDD! When it does the triple power cycle test with the drives in, the third LED pattern is orange green.
At first I thought it was a stock BIOS corruption issue, so I soldered a header on the LPC and slid two different chips on it. One with X2 4983 and one with some crap like M8-plus. Neither changed the boot patterns. I have tried different D drives with HDD's and the boot results don't vary.
This detail may be important. I noticed but never addressed the original M$ dashboard on the original HDD appeared to be corrupted. The dash was labelled as 5960, yet in the settings page, the only option were the aspect ratio options, like widescreen, letterbox, and whatever the other one was. So there was no option to allow anything over 480i res or digital and DTS
audio. It looks as if it may have always been like this though because when it shockingly plays the boot animation without any drive in, the picture is in black and white on component channels and cables. In color on composite. Could this have anything to do with the reverse booting?
I don't remember the box always booting like this, but it has been in storage long enough for me to forget it's exact behaviors. All I know for certain is at some point it booted normally at least once and I was able to see the dashes goofy qualities. Previous stability of boot unknown.
Is it the Conexant video encoder? If so I have plenty spares and equipment to remove this one and replace with a known flawless Conexant.
Then what of the dash settings missing? _________________ 320GB ST3320620A 7200RPM 16MB Cache

I had a softmod that had a green screen by using a component cable and it was corrected when I installed the HD version instead of the standard version on UnleashX _________________ Xbox Halo Green Limited Edition v1.4

That makes sense. I never softed this box though, I just mounted all the RAM chips and chipped it with a pre-loaded HDD like I always do.
I managed to mend it though. The culprit was either the biggest resistor under the GPU failing or the primary RAM capacitor's positive joint rotting. Not sure which because I fixed them together then tested it working. All I know is the resistor was leaking badly out of both ends, and the caps one joint had been made incomplete by tarnish that had spread from the original rusted putrid case to the solder somehow. I couldn't see it at first, the rot was only at the top of the joint, blocked by the cap itself. Until an accidental
wiggle exposed it.
Anybody with crossed boot patterns, either replace that front right 3300uf 10V cap or just redo the joints. Check the bottom side chipset resistors too. _________________ 320GB ST3320620A 7200RPM 16MB Cache

I didn't know that resistors leaked, electrolytic caps can but a resistor? Which resistor was it?
Was the A/V cable plugged in? Green/Orange flashing pattern occurs if powered on without it plugged into the back of the Xbox.

I phrased that poorly. It was the old flux leaking out of the solder joints themselves. You know, that tough, thick, dark yellow gunk that forms mostly around surface mounted passives. Anyway, looking again I think it's actually a cap. It's on spot C4P20, and it's the only K0 157 6K right under the GPU.
The AV cable was in the whole time. That's how I was able to see the boot animation when the drives were out (and simultaneously hose my pants with urine). _________________ 320GB ST3320620A 7200RPM 16MB Cache
