Yes and NO your tv is a LED. To be exact it is a LED Backlight LCD TV. An LED-backlight LCD television is an LCD TV that uses LED backlighting instead of the CCFLs used in traditional LCD televisions. It is not a true LED display but is called "LED TV" by some manufacturers.[1] The use of LED backlighting has a dramatic impact, resulting in a thinner panel, less power consumption and heat dissipation, and a brighter display with better contrast levels.

Ur Tuner signal board have problems or dead.Ur power LED light indicator stable for a few mins before the power LED light,and the OPC LED light indicators flashes?After the POWER light and OPC light indicators flashes,just push the power button again for the power recycles again.Probally have to pushes the power button 3 or 4 for power light and opc light indicators flashes,the LCD backlght will lght up and work.Sharp tv have this problems alot,very common in Sharp LCD tvs.

This problems very common in Sharp LCD tvs.The Tuner signal board have problems,every times the power LED,OPC LED lites up,just push the power button on again,wait see if the LCD backlight lite up and works,not the Power lite and the OPC lite LEDS flashes again.You,just have to push the power button again,sometimes u have to push the power button at least 6 or 7 times to get the Power LED stable,and then LCD backlight,come on than the tv work.Not sure,but if the Power and OPC lites keep flashing,after u pushes the power button at lest 10 or 12 times,and the LCD backlight dosen't come on and the tv don't work.I think,it time to change the Tuner board is completely dead.I have a Sharp LCD tv, I do this everytimes pushing the power button at least 3 or 4 than the power LED stable,and the LCD backlight come on than the tv work.Not a plaw in the power supply like those capacitors in many LCD models tvs,but some included Sharp Tvs is the Tuner signal board is not very good in design,use the tv awhile the Tuner signal board have problems recieving the power to it Tuner board components.

If your pc works on another monitor. I would recommend you buy a new LCD monitor or a used CRT.

The best solution if your computer works is to buy a LCD screen, I've thrown out my 17" crt screens they aren't worth anything these days. You can get a used crt from ebay


Over here where I live I bought a used crt for 25usd thats was over a year ago.

Theres really no point in trying to repair the screen if its broken, buy a working one or a brand new lcd.

Good luck.
