Finally decided to get out my old XBOX and modify and Upgrade it. I installed a larger hard drive and everything seemed to be working fine. After a couple times of using it, it would give me error code 7. I opened it back up and put in the stock hard drive. The XBOX powered up and worked perfectly. I then put in the upgraded hard Drive and error code 7 again. I hooked up an external power supply to the hard drive and booted the XBOX. It worked perfectly with the upgraded Hard Drive.
I then checked all the voltages with a meter on the stock 1.6 power supply. They are all low. The 5 volt shows 3.9 and the 12 volt shows 9.57
Apparently the stock drive and motherboard can get away with running at those low voltages , but the new drive needs more power.
I am not a genius when it comes to repairs, but I have been able to make my way through them on various electronic items for many years. I have always shied away from power supply repair, but as these XBOX units are getting older and harder to find. I might need to learn a little more for the future
Can anyone steer me in the right direction to troubleshooting the repair of the low voltage? The power supply is a Delta DPSN-96BP. I have inspected it thoroughly and see no signs of leaking or swelling of any caps. I know that does not mean they could be bad though. I see no burn marks and nothing smells funny.
Thanks for any help. Chris
