[d4nny801]

Hi guys, i recently just got my xbox JTAG'ed was great i had a e79 error and took me a while to find out the problem. but i come through and got it to work.... But then i picked it up after booting it up nda dropped the LPT connector onto the motherboard! now when i plug it in and try turning it on the power brick light goes red and it does not boot. turn the plug off and on power brick light goes orange as usual until i try to turn on the xbox, then goes red again. what have i done?! im really gutted after how long it took me to JTAG the thing! any help would be great! i hope this can be fixed with a solder iron and a trip to maplins

I doubt it mate sounds buggered :-( but would need to see it

Are there any noticable scorch marks where a cap may have blown?

[d4nny801]

ive de-soldered the lpt cable, checked for anything that might short it, there no physical sign of damage that i can, what should i be looking for? it goes to boot green light for like a second then fans twitch then power supply goes red. i think it is a short on the board somewhere, but not cetain. if it helps the connector fell on top of the purple circle thing with the coil around it? is it this i have broke, any suggestions would be fantastic.

What secondary error code do you have?

In which case, I would ask you to check the cap that it fell onto and if needed, replace it. If possible, could you post an image of where you think the LPT fell?

here is my motherboard, the area circled is where the LPT connector comer into contact with the board. the purple circle with the coil around it is where the connector touched i think....hope this is useful

Does that point underneath the board look OK? Test it with a multimeter, see if you get continuity.

i dont think you can test a mosfets without removing it can you? i have "acquired" another xenon board off a friend i will maybe try removing the two mosfets of mine in the morning and replacing them with the ones of the other one. i will post the results tomorrow hopefully if all goes well.

Your JTag soldering doesn't look too clever. Look near the HDD port, why is there a blob of solder on the cap with the wire attached to it? You should ideally be using diodes. Also, at the top left near the screw hole, the soldering looks pretty bad there too.
