It sounds like you have already done some troubleshooting by replacing the TCON and main boards, but you are still encountering issues with the TV being stuck in burn mode. Here are some additional steps you can try:
Power cycle the TV: Turn off the TV and unplug it from the power source for a few minutes, then plug it back in and turn it on again.
Check the cables: Make sure all cables, including the HDMI and power cables, are securely connected to the TV and any external devices.
Reset the TV: Look for a "reset" or "factory reset" option in the TV's menu settings. This will restore the TV to its default settings and may help resolve the issue.
Contact the manufacturer: If none of the above steps work, you may need to contact the manufacturer for further assistance. They may have additional troubleshooting steps or be able to repair or replace the TV if it is still under warranty.
Hopefully, one of these steps will help resolve the issue with your TV being stuck in burn mode.
