No one wants to send their TV set off to the manufacturer for repair. The process can be costly and, in some cases, lengthy, requiring weeks for the television to arrive, undergo service and returned to you. Sometimes simple problems can be solved at home. Using a few repair techniques, you can fix common problems such as no audio or video and running lines during programming.
Fix the television feed by checking that the A/V cables are plugged into the right sockets on your cable box or satellite receiver. The A/V cables run from the back or side of your television to the back of your cable or satellite receiver. Both the cables and the sockets are color-coded.
Troubleshoot a black screen or no volume. Check that the right video input is used for the television and other media. Click the "Input" button on your remote control and select the right one to restore audio and video capability.
Demagnetize a rear-projection television with a magnetic coil, which can dramatically improve imaging. If lines and other shadows appear when you watch television, use the coil. Holding it in your hand, rotate the coil in circles across the entire length of the television screen. The coil should be no more than ½-inch from the television screen.
Remove a burned-in image by turning off the media that was in use (such as a blu-ray player that was paused for too long). The TV will return to its normal programming.
