TV Has Sound but No Picture Can It Be Repaired
If your TV has sound but the screen is black, one of the most common causes can be a failed LED backlight. The TV may still turn on, play sound and respond to the remote, but without working backlights, the picture may appear completely dark.
Another possible cause is a faulty power board. The power board supplies electricity to different components inside the TV. If it develops a fault, the TV may turn on partially, produce sound, but fail to provide the correct power required for the display or backlight system.
Other possible causes include:
-
Failed LED backlights
-
Faulty power board
-
T-Con board failure
-
Mainboard problems
-
Loose internal connections
-
HDMI or input problems
-
Display panel faults
At Express Gadget Repair, we can inspect your TV to determine what is causing the no-picture problem. If the issue is caused by the backlight or power board, these components can often be replaced rather than replacing the entire television.
This can make TV repair a worthwhile option, particularly when the television itself is otherwise in good condition.
Can Express Gadget Repair Replace the Backlight or Power Board?
Yes. If our inspection identifies a faulty TV backlight or power board, we can assess the replacement options for your particular TV model.
A backlight replacement may restore the illumination needed to display the picture, while replacing a faulty power board can restore the correct power supply to the TV's internal components.
However, every TV is different, so we recommend an inspection first. We can determine whether the fault is related to the backlight, power board or another component and provide you with the appropriate repair option.
If your TV has sound but no picture, don't assume you need to buy a new TV. Bring it to Express Gadget Repair in Botany, Glen Innes or Mangere for an assessment and find out whether your TV can be repaired.
