LCD Television Screen Repair Tips


Fixing LCD television screens is difficult when the issues are hardware-related, but certain things can be done to ensure that you don't make a needless trip to the repair shop. You can ensure that the television is set up correctly, fix dead pixels on your own, and in some cases, if you have the prerequisite knowledge, make minor repairs within the set from home. However, the majority of large repairs must be made by the manufacturer.

Fixing Common Problems

  • Many problems with LCD televisions are simply setting problems. The first step is to ensure that all of the cables are securely connected and functioning correctly. If the connections seem tight but you receive only audio with a black screen, purchase some new cables and replace the old ones in case the cables themselves have gone bad.

    If the television is turning off seemingly randomly, check a few things out before assuming there is a hardware problem. Check the sleep and alarms menu and ensure that the TV is not set to go into a sleep mode at a certain time. Also, if your set has a screen saver, recheck those settings.

    If a black screen issue persists it could be a problem with one of the cold solder joints. It is possible to dismantle your television and follow the cold solder joints, looking for a broken one, which you can then re-solder. But this is not recommended unless you have fairly extensive knowledge of television circuitry. The problem could also be caused by a dead power supply or bulbs, and your best bet at this point is sending the television back to the manufacturer for repairs.

Fixing Pixels

  • If you are experiencing dead pixels on your screen you can often fix them by rubbing them or pressing on them to reactivate them. Do this by placing a piece of cloth over the area with the dead pixel and either pressing or rubbing on it with moderate force using something like the eraser of a pencil. If you can get a totally black screen while the TV is on, this will help you locate the pixel. Remember to be careful with the amount of force you apply so as not to damage any pixels.

Bigger Repairs

  • LCD televisions and plasma screens have limited do-it-yourself repairability. Even independent television repair stores are limited by the equipment and parts available to them. If a problem persists that seems to be larger than the aforementioned issues, consult your local independent shop and, if they cannot help you, be prepared to ship the set back to the manufacturer for repairs. Also, keep in mind that replacing a cracked LCD screen is often more expensive than simply purchasing a new unit.
