Try unplugging and replugging after waiting.

my olevia a 232 s12 2nd hand tv . gift from a relative wont power on .just had the blue light on.i was able to reset my 32 inch olevia by pressing and holding down the power button much like a computer to reboot.might work for you.

It sounds like your main board has failed, given the issue with your sound and the LED light on the front panel. These are common signs of a failed main board.

The issue you are having is your power supply

Thank you

Your power supply module may have gone out.

I just repaired this identical problem on the same model TV. You have a bad power supply (also known as an SMPS). The board is model FSP271-4F02, and is about $75. Unlike the main board for this TV, you can find the power board relatively easily. Try shopjimmy, for example. Replacing the board isn't too difficult if you have a reasonable mechanical ability, have some tools, and are careful.

Mine had the same problem. You simply remove the dozen or so screws on the back and pop the back off. If you follow where the power cord goes into the tv and trace the wires you will see a small fuse. I believe it was a 5amp and cost less than a buck. I'm not sure why mine blew but I have had no issues since.

What did you try so far? The main power supply MUST have at least the 5V standby supply section working. This 5v is used by the main control board to send out the command to turn on the main power supply section which will power up the rest of the TV circuits when the power switch is activated either by the power button of remote or on the TV powern button. Look for this 5v first.

we hit the reset button on the back of the tv and then it worked.
