How to Troubleshoot a Samsung LCD TV with No Powerby William Pullman
Problems with a television's power supply are often difficult to repair without the need of a qualified service technician. Before sending your television in for repair, try troubleshooting the television in your home. Though most problems require service, other causes of a television not powering on are from outside sources. By troubleshooting your Samsung LCD TV you may save the time and money of having it serviced.
Check that the power cord is securely plugged into the power outlet.
Make sure that the power outlet is receiving electricity by plugging a different device into the plug and turning the power on. If the other device does not work you likely have a blown fuse or tripped circuit breaker.
Replace the blown fuse or reset the circuit breaker as needed. If it happens again, an electrician should assess the problem.
Contact Samsung Support if Steps 1 to 3 do not solve your problem. Only a trained service technician should attempt to fix the power problem with your television.
