LAPTOP PROBLEMS FOR REPAIR

In this case, the root of the problem is low signal strength in the set-top box cable that is connected to the LED TV. This problem might not show up if you plug that set-top box to an old television. The reason for this is that older TV sets required lower input strength to work. With the modern LED TVs set it’s not the case. They require stronger input signals. Thus, switching to an HD set-top box will most probably rectify the problem.
If the menu screen has the same problem, your TV may have a malfunction.
If the menu screen does not have the same problem, it is not a malfunction. You can change the picture settings to suit your tastes. See the descriptions below.
In this case, most probably the power supply unit inside the LED TV has issues. The power supply unit develops issues due to a sudden surge in input supply. Usually, the capacitors on the power supply boards fail. These problems are common in modern LED Televisions and the repair work is fairly simple and quick.
Disconnect the LED TV from the AC power, then press and hold the power button on the LED TV (not the remote) for 10 seconds. After waiting for a minute, connect the TV set back to AC supply and press power button once. Then try out other “sound out” from your TV to a set of speakers. If the speakers work, clearly the internal TV speakers are not working. If it doesn’t, it is most likely that the audio IC that drives the internal speakers has failed.
