The blue power light is on, but nothing works on the tv. No screen power, no display, none of the buttons and the remote does not work anything on the tv either.

    Already tried having it unplugged for days. When I plug it back in it still only shows the blue indicator light on. Nothing works, no power or functionality to anything else on the tv. No display, none of the buttons work anything and the remote control can not turn it on or off or have any affect at all when buttons are pressed. Just that little blue light stays on. The on and off button does nothing. Only unplugging it will get the little blue light to go out.

Hi

Thanks for using FixYa. This might have happened due to loose connections or cold solder joints on the AV Board(X-sus board). Bang on the upper side of the TV with your hand and see whether it is staying on for a long time or staying on and off. If the issue is slightly resolved but not completely, then it means that a wire, connection or cold solder joint is loose which you can check after opening the back cover of the TV. If it doesn't work then try to reset your TV by switching it off and unplugging it from the mains power supply for 8-10 hours.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
Rylee

    Hi




    Its due to loose connections inside the TV. It maybe due to faulty X-sus board connections or a faulty power supply. To be sure what is causing the problem you can check if the fans are working when you switch the TV on. If not then it is a faulty power supply. You can check all these things in the morning and then revert.




    Please do revert for further assistance.

    Thanks

My son bought an AOC LCD TV (model L24H898) last month and connected his laptop and XBOX to it. Yesterday we lost internet connection and the screen on the TV went blank. Now none of the button on the TV...


According to the manufacturer, to reset the entire unit do the following:
1. Press and hold "Menu" and "Channel +" on the TV. 2. Using other hand, press the power button. 3. A small screen should appear in the top left part of the screen. 4. Using the remote, select "Memory Recall" and select. 5. Power off and re-boot the computer 6. Run channel auto-scan to regain the picture.
