The LCD TV repair is the most common type of requested repair in the TV world these days. Before attempting to conduct any repairs, make sure your television is no longer under warranty and that it has been removed from power supply. Should any of the following repair tips seem insurmountable, call Mort’s TV & Video for advice or TV repair info, sending a summary of your LCD TV symptoms to one of our techs.
LCD misbehaviors that warrant TV Repair:
Your best bet may be to recycle the TV. A repair may be a little costly in comparison to scoring a new television. If your screen is just in something of a bad way, go with the old stand-by of unplugging it for a minute or so—this action forcing the main processor chip to reset and frequently solves the problem. Should this approach not solve the problem, go the alternate outlet route, it may just be that it is the outlet that is at fault and not the TV.
Lines on Screen-
Are lines, dots or darkness hovering on any portion of your screen? Try to give the unit some love taps—softly working your way around the screen’s frame (DO NOT DO THIS TO THE SCREEN ITSELF!) in hopes of this solving the problem. The condition may worsen which illustrates the likelihood of a damaged connection within the display itself –this could be that cables from the circuit board are plugged in incorrectly, unplugged altogether or are bent. Save yourself some time and either buy a new TV or take to a shop for a TV repair.
If your LCD TV just went off on its own, did you hear a distinct pop or series of popping noises? If so, once plugged back in and powered on, is there a blinking light (standby or power)? These symptoms can be indicative of power issues such as none, intermittent power, distorted display, even no picture and sound or just or sound with no picture. These problems tend to be related to loose cabling and/or a faulty board.
Dead Set/Power Issues-
This condition appears to be no power because there are no LED lights and no reaction from pressing the power (or any other) button. “Dead set” status should only be determined as a possible cause if you have already tried to plug the TV into an alternate working power outlet. Should this not solve your problem, unplug the TV, removing the back cover. You will want to check the fuse on the power supply board, using an OHM meter and/or continuity tester. Power surges often cause fuses to blow—similar to what unfolds in your car. Go anywhere that fuses are sold, find the corresponding type and replace it. If you get the TV back to proper functionality but the fuse blows again, this points to a likely problem with power supply. A TV repair will be your best bet.
