Troubleshooting
If you encounter any issues with your XTRONS TX123GS, please refer to the following common solutions. For more detailed troubleshooting, consult the downloadable PDF manual or contact customer support.
Common Issues and Solutions:
- Slow Startup or App Performance: The unit features an 8-core processor with 4GB RAM. While generally smooth, performance can be affected by too many background apps or large data loads. Close unused applications to improve responsiveness.
- Display Resolution/Quality: The unit has a 1280x720 QLED display. If the image appears rough or low quality, ensure the video source is of sufficient resolution.
- Audio Sync Issues (e.g., with TV tuner): If audio and video are out of sync, especially with the digital TV tuner, this might be due to signal processing. Ensure a strong signal and try restarting the application or unit.
- Radio Frequency Issues: Ensure the radio frequency settings are correctly configured for your region. If the unit cannot tune to local Japanese frequencies, check the settings or consult the manual for region-specific adjustments.
- No Image on Rear Camera / Black Screen on Reverse:
- Power cable connection is unstable: Ensure all power connections are secure.
- Wiring is disconnected or interface is not fully connected: Check all wiring, especially the RCA connectors. For rear cameras, ensure the yellow RCA interface is used.
- Incorrect RCA interface connection: Rear cameras typically use the yellow RCA interface. Connecting to other video input interfaces may not work.
- Video signal incompatibility: Most Japanese market monitors and navigation systems support NTSC (CVBS) video signals. If your camera uses a different signal (e.g., PAL), it might not be compatible.
- Trigger wire error: Ensure the rear camera's trigger wire (typically connected to the reverse light +12V) and the monitor's reverse signal wire are correctly connected.
