It is blinking because it sensing shorted circuits that are drawing too much current so it goes into safety shutdown mode, the shorts will more likely to be in the inverter board which draws the most power from the power supply module, try disconnecting the power cables to the inverter board to see if the TV will come on without the pictures but still has sound.

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

TV won't power on, repeating doulbe red light blink


Question Television is not working, screen is black, blinking red led.
Answer Television is probably malfunctioning due to electrostatic discharge. Try resetting the television by unplugging it from the power outlet for 10 seconds.
  1. Make sure that the power cable on the display and the VGA cable with trailing audio cables are connected correctly (use the originally supplied VGA cable.) between 'MONITOR' of the TV and 'VGA1' of the display.
  2. Make sure that the display is switched on.

Sharp 37 inch aqous tv power button blinking red


If the blinking light seems to be blinking in a pattern, then it is an error code. The end result in any case, is the main power supply is not functioning properly, or the backlight power supply has a problem.

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.
