Hi there. I would advise you to unplug your tv from the wall. Wait approximately 5 minutes. Hold down the power button on the tv for 15 seconds without the tv plugged in. This is what they call power cycling. If plugging back in the tv does not work; you might have a power board issue. A typical power board/circuit board repair runs from $25 to $125.

Did you try to use a flash light to diagnose?

Take the screen off connect power and watch LEDs if any don't flash its LEDs only needed to change faulty strip if they all flash its probably t con boards.

Hello, The real problem is on your TV 'scircuit. Due to high electric power supply there might be a short circuit damage. It's better you call up your service technician and ask him to offer you a onsite support.

Try manually pressing the power/standby button on the tv (side or bottom) the red light should appear, most modern tv's will turn on simply by pressing the channel up or down on the tv itself.. But unfortunately in most cases, this seems to be an internal surge and needs a professional to inspect..

If set turns on with the power button on set the remote is : not set to TV, not programmed for the set, has bad batteries or is bad.

If it even works one function it may need to be reprogrammed or taken apart to see if works---you can test the remote by pointing it at a digital camera with a LCD screen and pressing buttons to see if it makes the screen flash on the camera.

Test the remote first

Emerson TV is one brand we have a low percentage of success getting our remotes to work. If it still doesn't work, we could try replacing the remote.
