LED TV screen goes blank<\/h4>\n\n\n\n
\"blank<\/figure>\n\n\n\n

In this case, most probably the power supply unit inside the LED TV has issues. The power supply unit is responsible for receiving current and sending it to all the components of the LED TV. The power supply unit develops issues due to a sudden surge in input supply. Usually, the capacitors on the power supply boards fail. If you disassemble the LED TV set, you could verify this by spotting a leaking or bulging capacitor. These problems are common in modern LED Televisions and the repair work is fairly simple and quick. It is recommended to find a technician as replacing the capacitor would require soldering skills.<\/p>\n\n\n\n

LED TV has Horizontal lines on start-up<\/h4>\n\n\n\n

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\u2019s not the case. They require stronger input signals. Thus, switching to an HD set-top box will most probably rectify the problem.<\/p>\n\n\n\n

LED TV with no sound output<\/h4>\n\n\n\n

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 \u201csound out\u201d from your TV to a set of speakers. If the speakers work, clearly the internal TV speakers are not working. If it doesn\u2019t, it is most likely that the audio IC that drives the internal speakers has failed. It is common in these sets as they use inexpensive low powered amplifier ICs that heat up and fail. A simple replacement of the audio IC will do the trick here.<\/p>\n\n\n\n

LED TV not connecting to WiFi<\/h4>\n\n\n\n

The first step is to locate if the problem is in the TV\u00a0 or the router. If the TV has no problems in connecting to your mobile device, then probably the router is at fault. Try updating the firmware of the router. If that doesn\u2019t work, factory reset the router. <\/p>\n","protected":false},"excerpt":{"rendered":"
