Hello everyone. I have not done anything with my original Xbox 1.6b since I softmodded it over 15 years ago, and recently it stopped powering on. I've tried googling and researching, but the loss of Sickmods (and others that I probably don't know about) has made it difficult to find information. Attempts So far: Eject or power button does nothing. Replaced the 5 main caps that are known to leak (I'm pretty sure I did this 10 years ago as well, but had parts on hand so did it anyways) I have replaced the transistor near the clock cap (q7c2) I'm pretty sure its the power supply itself, (Its the Samsung Tuscany one) so I have been trying to modify an ATX supply to use to test. On the earlier versions of the XBox there are lots of information and adaptors, but not the 1.6b. The pinouts I have found for the 1.6 xbox (See below) show it needing 4 lines on 5Vsb, and only one standard 5V line: I'm pretty sure this is backwards, and it should be 1 standby line and 4 regular, can someone with more experience confirm? The other question is regarding the N64Freak adaptor board diagram: From what I have read the 1.6 uses 5Vsb instead of 3.3Vsb, can I omit the LM3490, the 33uf cap, and the link to the ground plane like so: Thank you in advance for any help you are able to provide, and if you have any good tips for a guy who is 15 years out of the scene, let me know.
