Hello guys, This post will be somewhat long because I want to include as much relevant information as possible. I have a v1.1 NTSC-U Xbox console, which I purchased brand new back in 2003. I modded it with a Xecuter 2.0 Pro mod chip sometime around 2004. It worked great for 2-3 years with no issues whatsoever. Then, out of nowhere, it started to intermittently FRAG. Sometimes it would boot just fine, but other times the Xbox would flash red and green and require me to reboot it 10 times in a row before it would boot to dashboard. Also, sometimes the Xbox would boot just fine and work for 2-3 hours straight and then, for no apparent reason, lose the video output. Interestingly enough, it would lose the video output only, but not audio. I tried different BIOS versions as well as different banks on the Xecuter 2.0 mod chip, but to no avail. After all that, I decided that it was too much trouble and just stopped using this FRAGging Xbox. Fast forward to 2020, and I decided to connect this old v1.1 Xbox to my TV and test it out. It worked great for the first two weeks, but then started FRAGging just like 14 years ago. It behaves exactly the same way as it used to – it might boot just fine 10 times in a row, or it might FRAG 20 times in a row. I reflashed the BIOS again, but to no avail. I also noticed a few more things. First, the removal of the DVD drive and/or hard drive does not seem to affect the FRAGging at all. The console can still FRAG with both drives completely disconnected. Also, if the Xbox boots to dashboard with no issues, I can easily make it lose the video output by knocking on the table on which the Xbox is sitting or by touching the AV cable. If I reboot the console immediately after that, the Xbox would usually FRAG. Bad AV cable, right? Nope. I tried four different AV cables/adapters and this is happening with all of them. All said cables work perfectly with my v1.0 Xbox and no amount of knocking on the table or touching the cables can make this second Xbox lose the video output. Here is the list of AV cables that I tried with the same result (i.e. intermittent FRAGging on my v1.1 Xbox and no issues on my v1.0 Xbox): 1. OEM Microsoft Composite cable 2. OEM Microsoft AV pack 3. OEM Microsoft HD AV pack 4. Third party HD AV pack Here are a few more things that I did: * Sprayed the AV connector in the Xbox with DeoxIT D5 and inspected it for damage * Reflowed all solder joints on the AV connector, twice * Inspected the traces on the motherboard near the AV connector Here is a list of things that I could still do (but would rather not): * Stop relying on the AV connector. Instead, solder the wires to it and add component video and coaxial audio jacks to the back of the Xbox console. Unfortunately, there is no guarantee that this will solve the FRAG issue. This Xbox was used by an adult and was never dropped or abused. At this point, I am not sure what else I can do besides soldering wires to the AV port and adding audio and video output jacks to the back of the Xbox. Does anyone have any idea of what might be happening? P.S. The pictures of the motherboard are attached to this post.
