my modded original xbox wont turn on...

[TheNew]

hello everyone i have a hardware question i have an old modded xbox 1 when i press the power button once it turns on for a split second and you can hear the fans start then it turns its self off does it again and turns off then it boots and it flashes green and orange any ideas? i thought it might be the power supply so i bought 2 new ones installed it and it still does it

ANY help would be amazing


thanks:shrug:

here is a video link of my issue http://www.youtube.com/watch?v=WZFQMg9f_H4

Bad HDD will cause that as well, so will lacking a cable in the video port. Check the modchip as well, make sure it doesn't have broken joints and such.

no modchip its a t-sop i believe

In the video you don't have a harddrive or a DVD-ROM, pop those in and then tell us what it does as an orange light flashing typically means you don't have a video cable plugged in. However different BIOSes do different things for different reasons.

There is also a pin header soldered into the LPC bus telling me it likely had a mod chip and probably still needs it.

My guess is that it's trying to boot from the LPC bus but since there isn't a modchip it is supposed to do what it's doing but instead of orange it usually flashes red/green. Without a video cable it (should) do what you're seeing there.

hi APE thanks for the advise however it did the same things as shown in the video with everything plugged into it. i have to go to work now but tonight i will plug everything back into it and make a new video of it trying to boot

I'd have to guess that it's orange due to the BIOS being modified to flash orange for whatever reason. I'd highly suggest grabbing a Duo x2 (2x?) chip from www.dealextreme.com (http://www.dealextreme.com) and try to mount it on the pin header and see what it does.

99% of the time installing a modchip into an XBox will fix virtually all problems that are related to the software portion of the hardware. It looks like it'd boot just fine if it could *load* something.

But if you end up wanting to trash it I do need a new DVD-ROM.

I think I have 1 or two around here somewhere, and a few original hard drives too.

i am just bummer out because this motherboard has the ram upgrade :(

[shuma]

iirc when the consoles turns on off on off on off its usually related to loose modchip wires or a bad flash or needs to have bios reflashed.

[jinn]

Do you still need help?

[TheNew]

Naa I am just going to contact trusty for a few upgraded xboxes ^_^

TRY THIS FIX

[jinn]

Would you be willing to part with the motherboard?

Borrow thread

Is it possible to straight swap a STD HDD with a STD HDD?
If the HDD is broken wont the Xbox start? (STD or Modded)

No.

Seriously man it does look like the EEPROM is corrupted. (because of the fan spinning at maximum speed after the first boot attempt)

Did you play with that ? :shrug:

And unfortunately to boot it you need to either remove the eeprom from the board. It's a I2C eeprom which isn't hard to program with some LPT flasher cable and a program called "Pony Prog". :thumbsup:

You can use Yoshihiro's "LiveInfo Beta 3" to edit the eeprom dump and fix whatever is wrong. :thumbsup:

you can swap a HDD with another which has been unlocked if you have a modchip. For a softmod you can still swap Hdds but need to lock them with the HD key from the eprom. That's why I always make a backup of a box as soon as I get them.
If you have the files for C & E partitions you can use xboxhdm 1.9 to make a bootable CD to prepare a HD with an old PC with IDE connection. If you also have a Eprom backup, there are also tools on that CD to lock/unlock the HD.

Only if PC motherboards don't freeze the drive.

You can also boot a bios that has an eeprom embedded into it (assuming modchipped and externally flashable, otherwise reprogramming eeprom will be easier anyway).

this takes me back, not touched an xbox in years

I think the OP mentioned it was TSOP flashed. :shrug:

Hence my suggestion of programming the eeprom externally.

Mostly the repair method depends on how comfortable you are with removing an 8 pin SOIC from the board and putting it back later. :thumbsup:

Interesting, mine was doing the same thing so I registered to post how to fix it... My xbox was powering up but I wouldn't see anything on the TV, I'd just hear the fans going, but no picture.

I changed the setting in the chip # 2 to ON and now everything works. wow. :shrug:

[l_oliveira]

The XBOX SMC (System Management Controller or the "PIC" chip) is programmed to do that in case the main CPU spits an kernel panic or is unable to start.

It will power on, detect the problem, power off then power on again. If it does not boot, the SMC will cause the two leds to blink signaling that there is a fault condition.

Things that might cause the issue:

Corrupted flashrom (bad bios)
Corrupted EEPROM (bad eeprom or missing data in it)

Hardware faults related to modding (cut traces that could prevent the system from acessing the flash chip with the bios).

The system could be modded to boot from LPC bus (NOR FLASH line D0 connected to GND) and there's nothing connected at the LPC bus or whatever is there is faulty ...

Etc etc etc ... :shrug:

As per ODD BEHAVIOR on the power and eject buttons it's very likely that the console is being victim of a leaking SUPER CAPACITOR (the capacitor that keeps the real time clock running when the system is disconnected from the wall plug) and traces were corroded.

Be aware that the leaking SUPER CAPACITOR was the real cause of the XBOX fires back in 2003 and the power cables fiasco was smoke screen strategy for damage control.

If you like your classic XBOX and want it to be healthy for the years to come, open it up and TORE the damn SUPERCAP out. :rolleyes:
