I unplugged the TV and held the buttons down and it continued to flash. I continued to hold down the two buttons and replugged it in again and it worked. TV back up and working.

Unplugged it. After looking for a new tv online I decided to try getting it to work. So, plugged it back in and held down the power button, a red light came on, held down the power button again and an orange light came on, held down power button again and green light came on and tv powered on. This was simply a case of trial and success!

unplug, hold power button, plug in. If that doesn't work, unplug all the HDMI cables, unplug the power, hold power button, plug back in.

Damage to tv


Unplug it and wait 4 or 5 hours. The Glass+ should evaporate and there should be no damage done.

If the problem continues after waiting, you need to take the TV in for service.

Sharp aquos won't turn on


Any indicator lights on, if it is then you only have the standby 5v circuit working, you will need to have the power supply check out first, that is a starting point.

Please pack the Sharp back into your car & get the money back. One thing I love about this website is how folks will talk about the historic/chronic problems of things. Don't even worry about fixing it. Run, don't walk, back to where you purchased it. Next, consult a "Consumer's Report" type of ezine & find a better model!!

No POWER


How many times does the POWER led flash per second? (Dont worry about the OPC).

1x (steady constant blink) = Lamps or inverters
2x = Power Supply
3x = Main Unit

If i am reading it correctly, looks like the POWER led is flashing 2x, which means it is a power supply failure. Either way, your TV needs to have a board replaced, there isn't anything you can do to fix it yourself. Try locating your local sharp authorized service center to repair your TV (1-800-237-4277)
