Common Reasons for Main Board Replacement
Even the best hardware is not immune to failure. The BN94-12484X may need replacement under several circumstances:

Troubleshooting the BN94-12484X
Before replacing the main board, it's important to isolate the issue. Here are a few diagnostic steps that can help:
Check All Connections: Loose cables or improper setup can mimic board failure.
Perform a Hard Reset: Unplug the TV for 60 seconds and hold the power button to discharge.
Test Other Devices: Rule out issues with HDMI cables or connected devices.
Update Firmware: Sometimes, software bugs can mimic hardware faults.
Listen for Relay Clicks: If the TV clicks but doesn’t power on, the board may be receiving power but not distributing it properly.
If these steps don’t fix the issue, replacing the BN94-12484X main board might be the right next move.
