Wrong Display Settings

Choosing the incorrect display settings on your Roku TV can prevent it from working properly. If you have recently tinkered around with the TV’s settings, you might have accidentally set your TV up so that it displays a dark screen but still has sound.  

Faulty HDMI Cable or Port

HDMI cables and ports are designed to be durable and don’t usually break or become faulty. However, if you have pets or you regularly handle your TV’s cables roughly, they can eventually break. When this happens, it can affect the screen’s display. 

Damaged Backlight or Display Panel

Roku TVs provide excellent picture clarity, and this is due to their sophisticated LED lights. It’s rare for these lights to break but it can happen if you drop the TV or it experiences a heavy blow. A faulty backlight or display panel can cause some or all of the screen to appear black. 

Faulty Capacitor or TV Panel

Your TV’s capacitor and television panel are responsible for displaying images on the screen. When they become faulty, your TV might have sound but no picture. 

These components are made to last and don’t typically break. However, if you’ve recently dropped your TV, they could be broken.
