Your TV could be in-operational due to a number of reasons. Please follow the instructions here to determine the root cause in your case.
Step 1. Please check if your TV is plugged into the wall socket. If it is not plugged in, please skip to step 10.
Step 2. If it is plugged in, check to see if the little red LED light on the front of the TV is lit. If this red LED light is not lit, please skip to Step. 11.
Step 3. If the red LED is lit, then you should try to turn on the TV with your remote control. To do that please press the red button on top of the remote control. If the TV does not turn on, skip to Step 6.
Step 4. If the TV turns on & works fine then it looks like you may not have a hardware problem.
Step 5. On the other hand if the TV turns on but shows you a blank screen or hazy screen then you may have a problem with the video signal not reaching the TV & this will have to be debugged separately. Not in the scope of this article.
Step 6. If the TV red LED light is lit, but it does not turn on with a remote, then it could be the remote that is not working properly. To find that out, please turn on the TV manually by pressing the power button in front of the TV to see if that turns it on?
Step 7. If manual power-on works, then it looks like the TV is fine, skip to but there is a problem with the remote. It could be the remote is bad or may-be just its battery has died. To further debug this, you will need to change the battery of the remote & try to turn on the TV with the remote again.
Step 8. If the TV now works with the remote after swapping out the battery with a new one, then your Remote battery was the culprit. Your TV seems fine. Enjoy yourself!
Step 9. If however the TV doesn’t turn on with the remote, even after replacing the battery – then your remote is bad. You need to get a new remote from your local TV store.
Step 10. If your TV was not plugged in, please plug it in. After plugging it in, if the red LED light on the front of the TV is lit, then skip to step 3. above.
Step 11. If however the red LED light is not lit, it could be due to several reasons. Let us first verify if the power plug is not loose. To do that please look to see that it is plugged in completely into the wall socket. If it was not plugged in properly and you just plugged it in, please skip back to step 2.
Step 12. If however the power plug was plugged in properly, but the red light on the front of the TV is still not lit, then first check to see if you have a power outage in your house. To do that – please verify if other electrical devices in your house are operating properly. If they are not, skip to step 18.
Step 13. If all other electrical devices are operating properly in your house, then you should check if the socket in which the TV is plugged in is working fine? To do that, you should unplug the TV from the wall socket & plug it into a different socket. If you could not plug the TV into a different wall socket then skip to step 15. Otherwise, check if the red LED on the front of the TV is lit? If it is, skip back to step 3.
Step 14. If the red LED in front of the TV does not light up even after changing the power socket it is plugged into then it looks like you may have a hardware problem with the TV and it will need to be looked into in the service center.
Step 15. If however you are unable to plug the TV power chord into a different wall socket due to some reason, then you should try to plug in another electrical device like a blender, an iron or a blow dryer in the same power socket where the TV is plugged in. Make sure this is a known good device and you plug it in properly. If the device works fine when plugged into the same power socket as the one the TV was plugged into – it means the problem is not with your TV – it is with the power socket.
Step 16. To replace the power socket – please follow the instructions … Not in the scope of this article.
Step 17. If however, the test described in step 15 was successful, i.e. the new device you connected to the same power socket where the TV was plugged in worked fine, then it means the power socket is fine, so the TV must have a hardware problem and it will need to be looked into in the service center.
Step 18. If you have a power problem in your house, and all electrical appliances are not working, the TV will also not work – as it is an electrical appliance. Please contact your utility company to determine when you can expect power come back to your house.
