Top 5 Common TV Problems and How to Fix Them at Home
Television is one of the most used appliances in every home—whether for watching movies, news, or your favorite shows. But like any electronic device, TVs can face issues over time. The good news is that many of these problems can be identified (and sometimes fixed) at home without needing immediate professional help.
In this blog, we’ll walk you through 5 common TV problems and what you can do before calling a service center.
1. No Picture but Sound is Working
Symptoms:
-
The TV turns on
-
You can hear sound
-
The screen remains black
Possible Causes:
-
Faulty backlight

Loose HDMI connection
-
Damaged display panel
Quick Fixes:
-
Unplug and restart your TV
-
Check the HDMI cable and switch to another port

Try using a different input source (like a set-top box or streaming device)
If these steps don’t work, the issue may be with the internal backlight or power board, which requires a technician’s support.

Faint or strong lines across the display
