You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..

Tv went off and won' come back on.


Most likely you will have to replace the power supply. It is a very common problem especially in newer electronics. You can test it with voltmeter or multi-tester. They tend to get worn capacitor inside the power supply due to cheaper parts

Brand new Sharp Aquous 37". I turned the tv on and a blinking green light comes and goes. I tried to turn it off and the blinking green light still on and no picture and no audio.


Behind your TV, there should be a system reset button.
If this doesn't fix the problem, most of the time this means a part has failed inside the TV. I would use the warranty and take it back and exchange it. You shouldn't be having this problem right out of the box.
I would have them check the new one so you don't have to waste a trip.
Good Luck

An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.
