| Problem Description | Symptoms | Solution | Source |
|---|---|---|---|
| White Light of Death (WLoD) | No display. | Can be caused by anything in the HDMI circuit. (Encoder, Port, Filters, etc.) | Source |
| White Light of Death (WLoD) | Does not display normally but does when booting to Safe Mode. | - Test the HDD using CrystalDiskInfo or similar software to ensure it’s a good drive. - If the drive is good then the only other known cause is the HDMI encoder. | Source |
| Can’t read discs. | - “Unrecognized disc” showing up when any disc is inserted. - Disc is immediately ejected after being inserted. | - Can be caused by a dirty laser, try cleaning first. - If the issue persists, replace the laser. | Source |
| Can’t read discs or won’t accept discs. | - Check F6202 fuse. Replace if blown, if this does not fix the issue then the Renasas IC itself is likely to blame. | Source | |
| Controller not connecting. | - Does not connect when fully booted. - Does not connect when in Safe Mode. | - Verify with a known good cable. - If the issue persists then the Southbridge IC is likely to blame. | Source |
| Controller not connecting. | - Does not connect when fully booted. - Does connect in Safe Mode. | Bluetooth/Wi-Fi IC is the only known cause of this issue. Can only be replaced with the same version of the IC. | Source |
| No power to disc drive. | - Commonly caused by a blown fuse on the disc drive daughterboard. - If the internal fuses are good, this can also be related to fuses F602 & F601 on the mainboard. | Source | |
| Error SU-42118-6 | - Commonly caused by fuses F602 & F601. - Can be caused by dead Renesas IC. This is unrepairable. | Source | |
| Error CE-34335-8 | Replace the Ti 72 PXGI transistor near the hard disc connector. | Source | |
| Pulsing Blue Light of Death (PBLoD) | - Commonly caused by a dead HDD. - This could be a broken solder ball under the APU, you can increase pressure by adding washers to the bracket in order to test it. If it starts working after this then you will need to reball the APU. - If the above solutions don’t work, the culprit is likely one of the RAM ICs. They are known to go bad due to excessive heat. This can be confirmed by using a thermal camera. | Source | |
| ”Too many USB devices connected” error message. | In addition to error message, does not respond to any USB device. | - Check for physically damaged USB ports. - Check differential pair filters. - If the above doesn’t work, then for models CUH1000/1100 replace the USB HUB IC (GL3520) - For model CUH1200 replace the Southbridge IC | Source |
