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.

LED TV has Horizontal lines on start-up
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.

LED TV with no sound output
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. 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.
The Difference Between LCD and LED HDTVs
There are a lot of different terms thrown around when people start talking about high-definition televisions. Everyone knows that HD looks better than standard definition, but what makes one type different from another? The two most common terms you’ll see when shopping for a new TV are LCD and LED but what do they actually mean? And is there a big difference?

Well, the answer is yes—and no. But first we need to understand what these terms actually mean!

LCD (Liquid Crystal Display): A prevalent model of HDTVs, LCDs are flat panel displays through which light can pass or be blocked. The LCD doesn’t produce its own light; this is done by additional lighting (see backlit and edge-lit for more info). LCD HDTVs are available in a variety of sizes and have wide viewing angles, making them ideal for almost any size room.

LED (Light Emitting Diode): A semiconductor device that produces light from electricity. LEDs are often used to back light LCD displays, which results in a clearer picture.

What does all of this mean for you?

When it comes right down to it, the main difference between LCD and LED is that LED televisions are going to look better than other LCD screens. That’s not to downplay how good an LCD HDTV can look, since the picture quality can be stunning, but there’s no denying that there is, indeed, a difference between them. That said, there are other differences worth taking into account. LED televisions can be considerably thinner than LCDs, even coming as thin as 0.3-inches. This, however, when mixed with the clearer image, means that buying an LED television is going to cost more than an LCD TV.

So now you know the difference between LCD and LED. There are other differences between them, and even differences within them, but hopefully, now that you know the main things that make LCD and LED screens different, you can better decide which type of television is right for you.

Learn what you can do when your TV screen is black or blank, but your TV is turned on.

Here’s how you would fix a black or blank screen on your TV.

Ensure that the power sources for all your devices (TV, digital box, VCR, etc.) are securely connected to your devices and the outlet. If that doesn’t fix it,
Check that your TV is set to the correct input. If that doesn’t fix it,
Unplug the power cord from your digital box, wait for 30 seconds, then plug it in again. Wait until the box has fully powered on again, then see if the picture has returned. If that doesn’t fix it
