- Ensure the power button on the TV or remote is functioning.
- Check for any visible damage or loose components on the motherboard.
- Black Screen / No Picture:
- Confirm all display cables (e.g., LVDS cable) are correctly and firmly connected to the motherboard and the display panel.
- Check input source settings.
- Flickering Screen / Distorted Image:
- Inspect ribbon cables for proper seating and any signs of damage.
- Ensure the motherboard is securely mounted and not experiencing any short circuits.
- No Audio:
