XBox Won't Turn On, Please Help

Recommended Posts

Hello everyone,

I recently bought an Xbox and on the first day I turned it on and it booted up fine. Days later I am now trying to turn it on again and nothing.

No lights, no sounds. I have another Xbox and the cable works fine. 

What do I need to do to fix this issue!

Could be trace rot. Have you taken it apart and removed the clock cap and inspected for corrosion?

There are 3 fine traces along the outer edge of the xbox motherboard on the solder side (back side) of the PCB that carry the control signals from the front panel power and eject buttons to the PIC processor that controls power and eject functions.  The electrolyte leakage can be great enough that it runs down the edge of the board and has corroded these traces.  As the signals no longer carry the signals well all sorts of strange things can happen.  My Xbox would come on by itself in the middle of the night (ghost power on) until I repaired the traces.  

Take that clock cap out on v1.0-1.5 Xbox's and clean any leaked electrolyte from the top and bottom side of the board.  I've seen some that have leaked enough to get to the bottom of the case leaving a large area of dried up residue.  Most use vinegar to neutralize the electrolyte followed by isopropyl alcohol soaked q-tips to clean up the mess the little aerogel cap left behind since he could no longer hold is electrolyte.

Vinegar is acidic (read before 4.5 pH) and the electrolyte if acidic can't be neutralized by another acid so I think the electrolyte is alkaline >7 pH (i've seen printed that electrolyte can have a pH from 4 to 8, so it can be either acidic or alkaline).  I don't have any litmus paper to verify the pH.  Looks like I need to purchase some strips and test the residue on the next Xbox I repair.

      I TSOP'd one of my Xbox's (it also has a new 250 GB disk I installed) and I was "playing" with HeXEn and can't boot to a dashboard any more.
      My question is given good hardware and a bootable HeXEn disk, how can I do a full reset of the hard drive with a fresh install?
      I am new to this and would like to get to the level that what an "Out of Box" Xbox that is TSOP'd would boot up to that is comparable to a fresh install of Windows on a PC.
      Thanks!

      I got a system in today from eBay (of course in "Perfect Condition") except when I powered it up it had a Flashing Green Ring / Won't Fully Boot or Read Disc.

      I opened it up and found that nice dent in the DVD drive.

      Swapped out the drive and it worked fine.

      Thanks for the assist Blake!
