[/QUOTE]Bollocks. The Xbox has a working system to shut down when overheating, and that's in the weird cases where the fan stops blowing or something. A normal Xbox - modded or not - can run for years without needing to be shut off

Your wrong chancer, Troed is right. Ive had boxes on for months and there has never been a hiccup except for the lightning mishap. The only chip that is a problem is the MCPX but it has only been problematic in isolated cases. An easy fix for that is a heat sink.

*id take Troeds advice over a MS tech any day.

Well I still disagree and see the damage heat build up causes to electronics but every man to his own ideas and if you want to run your xbox continuously then its your box to risk it with. needless to say i won't be doing it to mine, I've repaired far too many pSu blow ups caused by heat stressed electrolytics changing esr to want to repair my own stuff.

Heh, I posted and missed the point of the post. The only *real* test you can do is remove all of the wires and see if it boots stock. I mean, short of testing every point with a voltmeter.... Clean up your solder points too cuz they are shabby. You are waiting too long to touch the solder to the work. If it takes you more than 3 seconds to get that solder to the point, start over. Wipe it on a damp sponge and redo it. If it trees stock then you have some work to do. Id say 95% of the time a box is fixable but it really depends on your abilities. Check the points over and over if its still fraggin then you need to get ready to buy another mobo, the time required to find the culprit isnt worth the 50$ or so dollars to just replace it. Good luck

Well... after cleaning some points it booted stock. I put the chip back in there and it booted to evox. All I did was check to see if it booted, I haven't turned it on since. I am interested in catdog2's comment about the wire length. Something told me that they were a little long, but I was under a lot of pressure to get it out and it was like 2 in the morning. The solders really aren't a testament to my capabilities. I'm going to redo all the wiring with shorter wrapping wire tonight. That way it will react better to the 33mhz signals.

I'm still not sure why it went down in the first place (barring the bad solder). It might be that the length of the wires set up too much of a capacitance on the LFrame point, the overvoltage heated the LFrame junction inside the MCPX and shut the chip down. Or it could be something a lot simpler, like someone kicked the box at night (...and didn't tell me) which shook a shotty solder loose. I guess we may never know.

Is the way I did the mod correct though? Should I have left LFrame floating? I'd hate to see the same thing happen twice.

Looking at the pictures (Its always difficult) I think you are bang on the right track re-doing the soldering as some on the LPC look not too good. I would just make sure the longer wire lengths do not rest on the heatsink when when you put it all back together. I don't think the length of them is an issue specially as you have had it working.
the heat build up overnight causes the board to expand slightly so any bad connections with the soldering on the lPC are slightly disturbed. Once these are all good they will not be affected again. (yes I know no-one else agrees with me about the effects of heat). I am sure you will sort this now whcih is the main thing

They say MS spent lot of money designing the air flow on the xbox. There's some factors that can affect air flow a couple well known issues are running without the top on ( or at least the drive trays installed ) and maybe the hard drive he added runs real hot, some do.

I'd first suspect a solder issue then maybe a burn in issue. They run demo Xboxes at the store in a plastic case day in and out without heat issues. Lframe is a negative active signal that only occurs for 2 33 mhz clock cycles every boot. A better test for lframe is flashing when it's active like 8 times.
