Xbox Series X
| Problem Description | Symptoms | Solution | Source |
|---|---|---|---|
| No power. | - Use a multimeter to verify 12V is coming from the PSU connector (Top row should be all 12V, bottom row should be all GND.) If not, test with a known good PSU. - A bad HDMI encoder IC can also cause power issues. | Source | |
| Powers off after roughly 3 seconds. | - If you just replaced the HDMI port, double check your work and make sure you don’t have any pins bridged. - Short present on 12V rail. Test for shorts around the PMICs. Try to remove surrounding chips one by one and test if the shorts are still there until you find the faulty chip. | Source | |
| Powers off after roughly 10 seconds. | - If you just replaced the HDMI port, double check your work and make sure you don’t have any pins bridged. - Short present on APU power rail. Test for shorts around the PMICs. Try to remove surrounding chips one by one and test if the shorts are still there until you find the faulty chip. | Source | |
| Powers off after launching game. | SSD is failing, replace by cloning to another SSD. | Source Tutorial | |
| No display. | Displays in low resolution mode. | HDMI encoder is bad, replace it. | Source |
| No display. | - Replace HDMI port. - Test EMI filters. - Replace HDMI encoder IC. - Check 2151 5V transistor, can be replaced with a similar transistor from the Xbox One ethernet circuit. - Replace the HDMI Boost Protection IC. This IC cannot be purchased so a donor will need to be pulled and reballed. Alternatively, there is a bypass board you can purchase and manually run wires for. | Source | |
| Update fails or system cannot start. | Error Code: E100 00000703 80910002 | This error indicates that the disc drive is missing. | |
| Update fails or system cannot start. | Error Code: E100 00000703 80910008 | This error indicates that the disc drive is mismatched. If the correct disc drive is connected, it is likely dead. The only thing you can try is to write the married data from the original disc drive daughterboard to another chip, though if it’s gone this far then it is likely too late to do so. | |
| Thinks it’s connected to Ethernet when it isn’t. | - Can’t connect to WiFi. - Connecting an actual Ethernet cable still doesn’t allow you to connect to the internet. - Cannot download update in Safe Mode. | - Try this software fix first: Go to Network Settings → Advanced Settings → QoS Settings → Restart Console. - If that didn’t work the only other known causes are either the physical Ethernet port or the Realtek Ethernet Controller IC | Reliable Source for IC |
