Common LED TV Problems and How to Fix Them

LED TVs, while reliable, can develop various issues over time. Here's a comprehensive guide to common problems and when you should seek professional help.

1. TV Won't Turn On

Causes: Faulty power board, blown capacitors, or main board failure.
Solution: Check power cable connections first. If the standby light is on but TV won't start, it's likely a main board issue requiring professional repair.

2. No Picture, Sound Only

Causes: Backlight failure, T-Con board issues, or panel problems.
Solution: Shine a flashlight on the screen - if you see a faint image, it's a backlight issue. This requires professional LED strip replacement.

3. Lines on Screen

Causes: Damaged ribbon cables, T-Con board failure, or panel damage.
Solution: Horizontal lines often indicate T-Con issues. Vertical lines may mean panel damage. Both need expert diagnosis.

4. No Sound

Causes: Speaker failure, audio IC issues, or software problems.
Solution: Try different audio sources first. If problem persists, speaker replacement or board repair may be needed.
