Television Repair in Nairobi, Kenya >0709004600
Seeing vertical or horizontal lines on your TV screen can be frustrating. Here’s what’s typically causing them and what you can do about it.
Common Causes of TV Screen Lines
Loose or damaged cables are the most frequent culprit. HDMI, component, or coax cables that are poorly connected or damaged can create horizontal or vertical lines across your display.
Panel damage from physical impact often produces permanent vertical lines. If your TV was dropped, hit, or pressure was applied to the screen, the internal LCD or LED panel may be cracked.
Graphics card or processor issues inside the TV can cause persistent lines. This is a hardware failure within the TV’s internal components that processes the image.
External device problems like cable boxes, gaming consoles, or streaming devices can also be the source. The issue isn’t your TV—it’s what’s connected to it.
Overheating can temporarily cause screen artifacts including lines. Poor ventilation around your TV can lead to component stress.
Quick Troubleshooting Steps
First, check all cable connections and try different HDMI ports. Test with different input sources to isolate whether it’s the TV or an external device. Power cycle your TV by unplugging it for 60 seconds.
If lines persist across all inputs and after reconnecting cables, you likely have internal panel damage or component failure requiring professional repair.
The bottom line: Cable issues are fixable at home, but permanent lines usually mean hardware damage that needs expert repair or replacement.
