Xbox Red Ring

[adadr]

Ok i know this might now be the best place to ask this question, but i will continue. almost a half a year ago now i was playing PC early in the morning and accidentally tipped over my xbox. i later plugged it in and i got the red rings. Error 73, top left section isn't glowing (first player i believe). i finally decided to get this fixed so i googled this problem and it said it could be two things. It could be a chip in it or the Video cable. so i plugged in my xbox and turned it on with video cable unplugged. it started normal with no red ring. then i plug in the cable, and red rings. do you think that it could be the video cable? i decided to ask this question because i didn't want to go blow 40 bucks on a new cable if it doesn't help (cash is short these days).

Must be the cable. Buy it from walmart, if it still happens then return it and your xbox is fukd.

Well, if a machine doesn't work with some component installed, does work when it isn't, and ceases to work when it is reinstalled, said component might have something to do with it. :P

you can further narrow the error down to the secondary error codes by pushing (i believe) your cd tray button and the controller sync button. i might be wrong, you dont normally retain that info once you get it fixed lol.
i had an e74 1022 which sucked. but that bitch ran for 24 hours a day most of the time, for 2 years. you read the secondary error code by the number of the quadrant.(player number)

EDIT: this is what an e73 is:
E73: I/O Hardware Error - Couldn't calibrate HSIO Bus from edram: this error is likely caused by a problem with the Ethernet port or supporting control devices
