If colored lines (1 to 10 lines) are going from the Top to the Bottom of the screen, the LCD TV may be failing. The only remedy for this problem
is to replace the LCD TV which can be very costly. If the lines are across the entire screen, then most likely the LCD TV is ok and another component is causing the issue. In the case where a TV failure is suspected, please don’t just dispose of the set, we offer a free and responsible recycling and disposal service. Call for details 801-486-7555
This problem is similar to the above problem except is usually happens when something has hit the screen and the internal glass is broken. The only repair solution is to replace the LCD TV. See the recycling area for more information.
If the TV set or projector will not start up normally and has blinking lights it usually means the self diagnostic system has detected a problem and the unit may need to be serviced. In some cases, unplugging the power from the unit and waiting for a few minutes before plugging it back in may correct the problem. If problem still exists then it will need to be serviced.
In most cases when a TV or projector is making unusual sounds or smells, it is an indication that something is wrong with the unit. It should be turned off immediately, unplugged, and brought in for service to determine the cause of the problem. Continuing to use a TV or Projector that has a problem may cause extra damage and cost more to repair.
In some cases where an input refuses to operate, it may just be a confused input port. Unplugging the power from both the signal source and the TV or the projector could possibly correct the problem and should be tried before bringing in a unit for repair.
In most cases when a particular TV won’t receive the digital channels, we have found that the TV set was manufactured before digital tuners were required and the TV does not have the capability to receive them. Other reasons may be is that the tuner system has been set to “Cable” mode which will result in no channels found when a channel scan is performed. Make sure the tuner setting is set to “AIR” mode, then scan channels again. If it is an older TV without a digital tuner an external converter box is required to receive digital channels.
If a TV set has normal sound, but a black screen it is a good indication that the backlight system has a fault of some sort. Sometimes an image can
be seen in the background of a dark screen. In most all situations this can be repaired at a reasonable cost. LCD panel replacement is not required with this type of failure, even with the LED backlit TV sets.
