The new generation TVs models are not exactly affordable, and, due to the smart technology they are based on, repairs are not so easy to perform either, but there are, a few common Sony LCD TV problems you can learn to solve by yourself, at home, without any special equipment.
Here are four of them:
1. Dead pixels are always listed first among common Sony LCD TV problems. The problem can be easily solved by acquiring a pixel correction DVD available in any local electronics store and online, for very affordable prices. Set the colors of your LCD TV to the maximum level and insert the DVD. Let the disk run. It will verify the screen for any dead pixels and solve the problem without any other interventions from your part.
2. The display of burned images comes second on our list of general Sony LCD TV problems. It usually occurs when the image displayed on the screen remains unchanged for a longer period of time. Even if it is not a severe problem, it can be very annoying, especially on the long term. In order to bring things back to normal, you need a computer. You first have to download a program designed especially for this problem. Run the program, create a blank image and, after you adjust the necessary settings, save it in one of the most accessible folders on the computer. Open the screen saver tools and set the newly created blank image as a screensaver. Connect the Sony LCD TV to the computer through a VGA cable. When the connection is made, turn the TV on and set the brightness to the maximum level. You should see the burned images disappearing and the new screen saver running. Let it run for a while, the longer the better, and keep the settings indicated above. You will see how the burned images become history.
3. Stuck pixels come third on our list of common Sony LCD TV problems, being encountered especially in the older models. In order to get rid of them, it is usually enough to slightly tap the screen area affected with your fingers or with some tool with a dull point, anything that will not scratch the extremely sensitive surface of the screen.
Of course, if the problem does not go away, you should not exaggerate and hit the screen too often or too hard. The main idea behind this strategy is to loosen the few pixels that got caught under the layers of the screen. If it does not work, the problem probably has deeper roots that you should leave in the hands of a specialist.
4. The last point on our list of common Sony LCD TV problems is the connection to the power supply or the poor connection between the screen and the other parts. If the display is totally black and does not light up when you push the power button, one of the explanations might be that the screen does not receive the electricity it needs in order to run. It could be because of a malfunction in the remote control or because of an interruption in the circuit between the screen and the power supply. Your only chance to solve this problem is to take things one at a time and identify the source of the problem. Replace the batteries of the remote control and verify each circuit to make sure that the power reaches the screen.
Of course, it is important to make sure that you do not overdo it with the repairs. If you feel that something is wrong or you discover any signs that the problem is more serious than it appears, you should take your LCD to a specialist, especially if it is still subject to warranty.
The common Sony LCD TV problems you can solve by yourself are basics issues that do not require special skills or equipment and that do not jeopardize the functioning of the TV any further.
