@Hina Based on the provided script, it seems you've prepared a support file for troubleshooting. To further diagnose the issue, you might consider the following steps:
Check HDMI Connection: Ensure that the HDMI cable is securely connected to both the Raspberry Pi and your TV. Try using a different HDMI port on your TV if available.
Verify Power Supply: Make sure that the Raspberry Pi is receiving sufficient power. A low-quality power supply or insufficient power can cause display issues.
Monitor Configuration: Check the display settings in Recalbox to ensure they are configured correctly for your TV's resolution and refresh rate.
Test with Another TV: If possible, try connecting the Raspberry Pi to a different TV to see if the issue persists. This can help determine if the problem is related to the TV or the Raspberry Pi.
Check for Firmware Updates: Ensure that both Recalbox and your Raspberry Pi firmware are up to date. Sometimes, firmware updates can address compatibility issues with certain hardware configurations.
If none of these steps resolve the issue, you may want to seek further assistance from the Recalbox community forums or support channels, as they may have additional troubleshooting steps or insights specific to your setup.
