FRAG w/ no video on first attempt at OpenXenium install...

[ka5ug4]

I'm trying my hand at both soldering (never done it before) and hardmodding by installing an OpenXenium chip onto my 1.0 Xbox.

As the title states, I'm getting nothing after my first attempt. My initial assumption was that I probably have a cold solder point on the LPC debug header, although the single wire could cause harm (I doubt that ones bad though.)

I remembered, however, that due to it not being used, I left pin 15 filled, as I was struggling to get it opened. While I doubt it, could that be causing any issues? Here's a picture of the joints for easier assessment:

Thanks in advance for any assistance.

I may be hallucinating, but your D0 is not hooked up, buddy. That'll make it hard for your chip to boot.  I've attached a photo of the 1.0 D0. Solder it to the D0 pad of the Xenium. D0 is pictured in my top down photo of the chip. Pad is all the way in the top right. 

Also, reflow those pins. Do it with a dab of flux and by sliding the soldering iron around the bases of the pins to try to get the solder to move toward the vias and to try to get rid of those balls. The original xbox already has big enough balls.  Yeah, you wanna be able to see the shape of each pin instead of having vague balls of solder sticking out. I've attached a photo of what you would ideally want them to look like.

Your pin arrangement is fine. In fact, 13 and 14 are optional. You don't need them for what you're doing. You only need the front 6 rows full. Also, it may be just the angle and a LOT of extra solder combined, but you may have a bridge between pins 12 and 10.

The d0 is attached, the photo was taken before I connected it. (⌒_⌒;) 

I'll try what you recommended soon, thanks for the advice!

I was wondering if you did that. lol. Woulda' helped to mention it.  

Let me know how it goes!

Just looking at the picture at your top row, are pins 5 and 6 bridged?  Also that 5 pin solder joint looks kind of iffy to me

Another thing I would like to point out is you should always use a good quality solder.  It makes jobs much easier and better.

I believe those are pins 12 and 10.

All of them look iffy. Although my first X3 install looked like that. And I installed an LPC rebuild so at least I had plenty of solder to work with. I can't remember if I installed the pin header and LPC rebuild at the same time. Probably. lol

Taping down the LPC header helps to keep it up straight as you are soldering it directly to the motherboard. You can also use blu-tack/white-tack, but I haven't confirmed that yet to be as reliable as the electrical tape.

It worked!

Thanks to everyone who helped me out!

Reflowing your pins helped?

Word. One of my box's LPC's is dead I think. No matter how much I reflow... I'll probably have to TSOP flash.
