How to Troubleshoot an Emerson LCD TV

When your Emerson TV won't turn on or experiences other basic issues, try to troubleshoot the problem before calling in a professional. In a worst case scenario, the television will require a major repair or it will be permanently out of service. Emerson flat screen TV problems are not excessively common, but like any television model or electronic device, the electronic components, LCD display or other sensitive parts and circuitry can fail as a result of stress or other overloading factors.

Emerson TV troubleshooting starts at the power source. If the television does not turn on, lags on performance or displays improperly, start by checking your power source. Make sure the electrical cord is firmly plugged into the television port. A loose plug can wreak havoc on performance. Next, remove the power prong from a power strip and plug it directly into the wall. Power strips can fail and cause performance issues in your television. With a secure and connected power source, you can now test the TV and move forward in the troubleshooting process.

Performing a reset on the Emerson TV is done through either a power cycle or a manual reset. To run a power cycle, simply unplug the television from the wall. Wait for a full minute while residual power leaves the television. Several minutes is ideal to ensure all power is lost. Plug the television back into the wall and turn it on. If your problem is resolved, stop here. A simple power cycle can resolve issues ranging from freezing to temporary display problems. If the power cycle does not work, perform a full reset. To run a factory reset, locate the reset button on the connector panel. It's a small, recessed button that requires a pen to hold down. Hold it for 15 to 30 seconds to reset the television. Alternatively, reset from your remote by locating the "Settings," "Advanced Settings" and "Factory Reset" option.

Your specific model may have small differences, so where possible consult your manual for the location of the reset button and navigating the specific menu system.

Hardware and failures in physical parts will require professional assistance. Your power board may fail and completely short the television. Power cords and other key components that are not easily diagnosed or replaced can also fail. When things go seriously wrong with your Emerson TV and a power cycle or factory reset fails to fix the issue, take the TV to an electronics professional. Also, check your warranty from the point of purchase or the manufacturer directly. You may be eligible for free repairs or a replacement.
