I, my xbox 1.0 with a X-bit 1.0 it´s allways on... i and a problem some day ago, that I couldn't turn off the chip holding da power button for 3 sec, I opened the xbox and repair a broken cable that conects to the chip and motherboard, today i turned the xbox on and i can't turnit off, some (rare) times she turns off, but don't turn on... I disconect taht cable but no sucsess, revode the D0 but the same with no chip... any clues?

[XBOXerPT]

with the front panel disconected she boots when i plug the power cable... same problem, ist´s not the front panel... if I push eject and power buttons she turns off (if conected long time to power), she powers off on evox shutdown, but some time she boots with no reason...

[XBOXerPT]

she it's connected to power for some hours, now she turn's off but don't turn on, only with eject button... she started to have this problems since I disconnected her from power 1 day ( and I had repaired  the on/off chip function before disconnect, it was working very well)

[XBOXerPT]

I disconnected her from the psu, then connected, and she turns on with the power cable, and reboots when I shutdown in evox...

[XBOXerPT]

If I hold the power button and the eject she disconnects, some times reboots..

[pablot]

check that all the resistors are in place and making contact.. and check continuity between the chip and the origin as in the picture below..

I let her pluged to the power for 12h and now it turn off snd on like new... push 3 sec and teh chip goes off, just like it should, can it a transistor?

Anybody know the values of those resistors ? They say 103 but I dont remember how to read SMD components

in pablot picture says 10k resistors

my xbox is having more problems, now it turn un if pressed for 2 sec, if more it reboots, so can't turn of my xbit (3sec reboots....) a friend daid to me that this problem is caused from dry transistors, because if I let it on some hours it stays allright , wath transistor can it be? in the mb ou the PSU? thanks for the help

[dcaway]

just pushing this up a bit, may help some other members, like it did me.  thanks pablot, fixed my 1.0 using the diagram and instructions posted above.

" xbox shuts off " " power cycling "

rebuilted my power trace to the chip, works 100% thanks pablot

Can someone post pictures of the resistors after being fixed please? Id like an idea of how to do it 'with wire and stuff' like flipflap. Im not too good at soldering and have little confidence in me being able to get the correct part etc ... but I know someone who does, Id like to be armed with as much info as possible when asking them to do it and explaining what it is.

Symptoms mine experiences are: powers up as soon as its plugged in, powers down after a little while, will only come back on back on using the eject button unless unplugged then plugged back in, powers down :/

[cackles]

Ok forget that last post of mine ... think it was my first here ... but anyways now I can solder, repair traces (I actually had to purposely damage and old mobo to experiment with repairing using wire and then copper tape), mod controllers with usb ports & extra buttons ... Im determined IM going to fix this xbox now, well carry out the repair ... need help with the diagnosis please.

I have continuity between the all the relevant points, except one, for a 1.0 box. Between the pink leg on the chip and the pink via at the top I have no continuity. Can someone please instruct me where to start with carrying this on.

[cackles]

also does anyone have/know of pics for the trace on the underside of the xbox between the two pink parts, be much appreciated, thanks.
