I have exactly the same problem. E75 / 1023 error and southbridge is hot, were you able to fix it?

Whoa

quite a deal going on there.  Going to re-read your article.

I will get back with.  See if I can help.  Real busy right now

Sounds like scrap parts to me. When it had the power error it might have been fixable. By power cycling you burned a short into a partial short that is more dangerous to components and probably has done permanent damage. The original short might now be harder to find. Test mosfets, one is probably close to shorting. Compare values with a good board. Also make sure all port pins are in good condition and not bent/shorting. Good luck.

ok thanks. any help would be greatly appreciated I would be very happy if I could take some parts off a few old junk boards to get this perfectly new one working

0003 - notes a power management issue.  Could have a dead or loose Mosfet.  Also might have some issue with small resistors or ceramic capacitors.  Those could be causing the excess heat felt thru the Southbridge.

I don't think that your drain to A/V shielding ground test is going to show a clear fault.  I could be wrong.  The way I test Mosfets is to remove.  Testing with a meter, both in continuity and diode function.  If there is perfect continuity in all the pathways - then Mosfet is dead.  Dpak or TO-252 mosfet have a switching function.  You also have to charge and release the switch to see if it is working right

I don't suggest using a Heatgun at all.  If it is a hardware store heatgun - with the force of its air - it could blown one of those small surface mount devices right off the board.

Another thing could be is that you lost a controller IC.

Another thing is the Southbridge might need reballing.  I can do a variety of repair work - even reballing

I'd be open to looking at this for you.  Look at it for free even.  If I could repair - would shoot you a good deal

Here's some Xbox Scene members for reference - done work for them

currently doing a job for ZeroprisonerZ

My feeling is the system could be salvaged   ... but maybe I'm wrong

does this appear to be a botched rgh?  i'd bet my paycheck it is.

no, not one solder point on the board looks like it has been touched since it was manufactured It must have died either on it's own or possibly a power surge

that would be great I would love to get this thing fixed how much might different issues with it cost? I wouldn't want the overall price of this to be more than another I could get working for cheaper

Well - the way I'm looking at this - is that this is a difficult thing to price.  You have multiple issues.  I think alot of my work would be for free on this one.  And I may not be successful

If I had to buy quite a few Mosfets or ICs from Digikey or another source it would be nice to be reimbursed.  Most of that is fairly inexpensive.

You'd have to send me the full console.  I don't have any parts or pieces of the Slim.  I mainly work on the Phats fairly regular.  Besides with the Slim - most people still have a warranty with Micorsoft.

Maybe I'll have to reball the Southbrige or the Cpu/Gpu.  It will be fun to work on a Slim.  So, I consider this something like pro bono.  If successful, a tip would be nice

We'll have to talk some more   ... I'll PM you
