Troubleshooting and repairing LED TVs can be a complex process, but understanding common issues and their solutions can make it more manageable. Here are some prevalent problems and general guidelines to address them:

1. TV Has Sound but No Picture

Possible Causes: This issue often stems from problems with the backlight, T-Con board, or power supply.

Troubleshooting Steps:

Backlight Test: In a dark room, shine a flashlight at an angle on the screen while the TV is on. If you see a faint image, the backlight may be defective.

T-Con Board: Inspect the T-Con board for visible damage or loose connections. Replacing the T-Con board may resolve the issue.

Power Supply: Check for blown fuses or bulging capacitors on the power supply board. Replacing faulty components can restore functionality.

2. TV Won't Turn On

Possible Causes: This could be due to a faulty power supply, mainboard, or external power source.

Troubleshooting Steps:
