Original Xbox shuts off at 1:15(s) what to do next, what to test for?


Recommended Posts

I got original xbox with intentions to only use working dvd drive to swap for parts but up found the existing hdd looked damaged as original owner said xbox was making arching noises.  I figured to see if I can get the xbox going again.  The machine powers on and shuts off at 1:15(s) that is with a working hdd.  I swapped the power supply from a working machine and same thing.  The dvd drive does work on a working machine.  I relocked the hdd from another machine to this one the hdd was softmodded didn't work.  I then reformatted with stock C and E files relocked hdd didn't work.  The original xbox powers on automatically when plugged in.  The original xbox has a Xecuter 2.6 mod chip.  I ran the setup without modchip installed, with modchip turned off and with modchip on - no improvements.  Any suggestions as what to do next?  What to test for?  When on stock dashboard I could not load a disc properly.  When on softmod dashboard disc would not load properly.  Not sure  if there is a ide cable issue?  Not sure if the hdd is setup correctly for given bios?  Not sure if bios is corrupt.

Dvd drive - works

Power Supply - works

Replaced Hdd

Motherboard ? 

Modchip ?

It sounds like there is trace damage on the bottom of the main board

This board had only 1 trace damaged but I have seen all 4 traces and the 5 to the  upper left of this pic as well.

What version board have you got?

The board version must be 1.2.  Conexant video chip, 2003 - 07 - 10 mfg date, 5101 kernal.  There is a missing flat rectangular resistor that came off when cleaning the board by the capacitor known to leak.  There must be something causing a short because the xbox original shuts off suddenly.  I managed to get it to run for 3 minutes.  What does one charge for replacing a resistor and doing a trace repair?  I don't trust the mod chip solder points behind the board they need to be de-soldered as well.

I might be better to post a pic of both sides of the main board.

If need be use a picture share site and post the links here.

Here's 14 photos of the xbox original damaged motherboard.  Photo 1 is from another xbox similar board version.  It has a resistor of 112 label.  That resistor is missing on the damaged motherboard.  Sorry the pictures are not that clear poor lighting and flash cause distortion on photo.  The green wire on back of the board, the solder is closer than the parallel trace lines possibly contacting.  There is heat damage on the back of the ide connector.

The part R7G1 is for the change from the power supply and the clock cap and the Xbox will work fine without it .

 

Can you give the board a clean especially around this location with isopropyl alcohol and if you can remove the small rubber square then post a good pic.

What happens when you power on with the modchip disconnected? and with the DVD and Hard Drive disconnected?
It should load up to a error screen.

Lastly the solder work on the LPC port looks a bit suspect but let's get it staying on for longer than a minute without the modchip 1st even if it's at a error screen

I have a 1.2 that had some damage from the clock cap, did the same till I cleaned it and put some solder onto the damaged track.

Have the same problems with Amigas the clock caps on them are in some cases 30 years old now and literally eat the board.

Best thing you can to with both is chop them off both will do fine with out a RTC function.

I got the xbox original to power up for 2:20(s).  I used hot glue at the green and brown wire solder points, it didn't improve on time.  I put electrical tape folded around the green and brown wire where they cross over ide connector and dvd power connector.  I found trace damage on photo 16.  Is it a matter of finding someone who does board level repair.  With the modchip disconnected, dvd drive and hard drive disconnected I get an error 07.  It then powers off at 2:20(s).  I used an eraser to clean the glue around the small rubber square.

If the trace has not gone completely you should be ok  I’ve had ones where there is still a connection but it acts intermittently as the current resistance is to high, build it back up with solder or conductive pen, fixes it. If the path is completely broken or gone you need to solder in a replacement link wire.

If you use a pen you can use nail polish to seal the copper  and pen to stop it corroding. Choice of colour is up to you.

How well does a conductive pen work?  Does the repair need an overcoat pen as well?

In my view it is a temporary fix but you can extend the time with a coating over the top and you will also get a better job by ensuring the trace has copper exposed before the conductive paint is applied and the surrounding area has been cleaned with isopropanol.

Have you tested that trace with a multimeter and and does it still shut down quickly with the DVD and Hard Drives disconnected?

There is a break on "Trace A" I tested with a multimeter.  "Trace B" there was continuity.  The original xbox shuts down at about 3:30(s) with DVD and Hard drive disconnected.  My softmodded xbox runs past 10 mins, doesn't shut down with DVD and Hard drive disconnected.

Have you fixed that trace and tested it again?

If you own a soldering iron you should be equipped  to do this. 
 

Just look on youtube for videos of track repair. Yours is not as bad as some.

It can be fiddly but with the right tip its do able.

In the process of finding a person who does advanced soldering.

That's fine.

Soldering is not hard but if you have not had a bit of practice getting someone else to fix this one is not a bad idea.

As for getting practice find some old electronics that will not matter if you destroy it and go to town on soldering wires to it and desoldering parts as well, Youtube is you friend for help to start with.

For a soldering iron get a basic temperature controlled station

Get some 0.8mm 60/40 solder and flux paste in a syringe.

I haven't done the repair yet but before I continue I would like to know if there is more damage than I thought.  I don't recall the hard drive making this noise when plugged in a pc.  Is this the result of a missing trace?  I called a few people if they would solder for me.  I got two quotes.  I decided if I am going to repair I will end up doing so myself.  I am looking into getting lead free solder paste and desoldering braid.  I have a budget solder iron but ended up vapourizing the solder that came with it.  Maybe solder paste is easier to work with as it is applied to the wire before melting it.

Here's the audio file of the hard drive seeking:   30(s)-end

Lead free solder is harder to work with you are better of getting some 60/40 or 63/37 solder and 1mm or 0.8mm

 

 

The hard drive in that audio clip is just about dead.

      I have a Jet Set Radio Future save that I have played around 25 hours in that I would like to be able to play on my console, but I haven't been able to figure out how to resign the save. The save has an "error reading JSRF save data" and doesn't let me use my save. The save originated in Cxbx-R and it won't allow me to move the save to or from the console without this error occurring. Not sure how to proceed from here, and would be grateful if anyone wanted to help me out. I have attached the save if that can help, thanks for your time.
