Because of the advancements in technology, numerous electronic products have emerged. However, some unpleasant things can happen because of this over production of models and devices. Good thing repairs can be done the do-it-yourself way. Here is a guide on how to do common issues on a Liquid Crystal Display television repair .
When your LCD screen has gone bad because of a high voltage problem, you can leave the television repair unit unplugged for about half an hour so it can reset itself. Now if that doesn’t work, check the circuit board that supplies power into the screen. But, if the television is under warranty, better check that first to ensure that you’ll get the proper solution to the problem. If the warranty has elapsed, check the trusty Internet and look for a service manual to help you identify the source of the problem and fix it DIY way.
When the screen displays on half of the picture, the problem would most likely be a “cold” solder joint in the inductor, capacitor or one of the components. If you know how to disassemble, assemble, and you are handy with a soldering iron, you can just reflow the cold joints.
If you are seeing only black screen on the display, try checking the cables if they are properly connected or plugged. You can also reconnect each cable one by one to make sure that they are plugged in the right input. If your flat screen has a screen saver, see how it is set. If these won’t work, maybe the rear projection, the lamp, or the panel has been damaged. Better to call the manufacturer’s customer service to help you identify such technical problem and replace what needs to be replaced.
