When you try to click it on, it immediately clicks back off. The power + OPC lights blink twice simultaneously, then the OPC light blinks once on its own, then the pattern repeats. What does this mean is wrong with it? Thanks so much!

This problem very common in sharp tv.The POWER,OPC flashes.First turn on have power LED indicator light stable at all? Tries the power again couple times will have backlight come back on,than it will work.Not at all more than 5-6 times than ur main turner signal board is the problem,must replaced.
Testimonial: "Took a part back panels looking at the circuit board power capacitors, plugged in TV to power outlet, and powered up normally."

the first thing that you need to do is to open the back cover of your tv.Go to the power supply section it is separate board where the power cord is connected.Using a multitester,plug in the power cord and measure for the output supply.see if the 5vdc ,12vdc and 24vdc are present..if one of this output is missing,replace the power supply board But if the output voltage are complete,replace the inverter board,It is a board that supplies the high voltage to the backlights of your monitor/screen....You can also try to reset the system of your tv by pressing the the small switch mounted on the main board press it twice while the power is on...tnx and good luck!
please vote for my help!

I had a same problem with sharp LC-40LE340E. The service told me to change motherboard but I decided to buy a new LG TV. The sharp TV I left unplugged for a 50 days and after that when I tried again the tv started normally. I was Really surprised. Don't spend money just wait and check again. [email protected]
