Hey, just tried installing my first mod and apparently it didn't go as well as I had hoped.. anyway..

Power on with eject button: Seems to boot fine, but I get no video at all. I hear the usual Xbox boot sounds and then I guess what is the normal menu background sounds (I never payed much attention before).

Power on with power button: Xbox tries to turn on twice (I hear fans start to spin, then stop), then the light starts flashing green/red (fragging?).

Is there enough info to single out what's likely the cause? Or as usual, do I just need to go over my whole solder job and make sure its good?

Thanks

If the box no longer boots correctly with the eject button (Chip Disabled) then you have a solder short somewhere or have damaged part of the board,knocked off one of the SMDs.
Check with a good strong magnifier for any signs of damage.

I'm having the exact same problem with an 1.0. I was wondering if the poster was able to fix the problem or if anybody has any specifics on the case.

Where do you have your D0 point and BT point connected to? and have you checked all your connections have not shorted anything?

I managed to take some high definition ( I think ) of the installation

DSC00015.jpg (4.1 MB) = way too much exposed wire on your BT connection.
i would recommend using the bottom-side D0, but your D0 point should be okay based on your previous post.
DSC00013.jpg (3.2 MB) = a bit too much slack on the eject/power button board.
DSC00016.jpg (4.0 MB) = no F'n way. that's a mess. you need to clean this up.
DSC00017.jpg (2.8 MB) = looks ugly - test your continuity from top of chip to bottom of board (on each pin).
DSC00018.jpg (3.5 MB) = all those little splash-dots of solder are probably shorting out all kinds of random stuff on the board. if they break lose they might get wedged between IC legs causing a short.

3 possibilities come to mind....

1) you may have parkinson's disease
2) you may have attempted this while high on meth or LSD.
3) you may have your soldering iron heat set way too high.

what kind of iron are you using?
the LPC needs to be cleaned up, and you have to start looking for little tiny balls of solder in bad places.

I'm using a 15w iron, is there any tutorial on how to clean an LPC ?

For you? No offense, but start over.

That's pretty messy. My advice would be to practice soldering before you try again. Get an old circuit board out of something broken or that you don't use anymore. Practice soldering and de-soldering the ICs, wire, and other components on there.

And also, use much less solder. Just a dab you want nice clean little joints. Soldering really isn't that hard, any one can do it.

Here is a short guide to basic soldering http://www.kpsec.freeuk.com/solder.htm

Here is a good video tutorial on basic soldering http://www.youtube.com/watch?v=I_NU2ruzyc4

Good luck.

Your soldering iron is not powerful enough. The solder has hardly melted, let alone flowed correctly. A cheap 15w iron will not be up to the job. A good quality one will. Buy a 25watt iron.
I did a few posts on soldering years ago which explain the whys, with some examples.

People new to soldering must spend a lot of time practicing on broken circuit boards before attempting to solder onto delicate electronics !

I can solder in a chip in a few minutes with a $10 cheap 15w iron but only after years of experience !

Get a decent soldering iron and clean the tip well and let it heat up properly before using it also tin the end of the tip ( melt a small amount of solder onto the tip of the hot iron and don't clean it off ) then heat the joint by placing the tip near the joint but do not press hard down on it ( you want the heat to do the work not pressure - it's not a screw driver ! ) now after 1 or 2 seconds bring some solder onto the hot tip thats slightly above the joint and the solder will melt and flow onto the joint. Wait a second then CAREFULLY remove the iron as this is a dangerous time as tiny balls of solder can fall or flick off the tip of the iron and cause a short anywhere on the motherboard which is what causes 99% of bad installs !

Thank you all for your great tips. After following your suggestions I think that I managed to perform a good installation.

Awesome News ... Looks great !

There are many modders, But only one...
