If total dead look for the fuse inside, if some lights on but set is not look at the power board the cord goes to for burnt parts or puffed up filter caps which are common.

I have a sharp 37" lcd tv,model # lc37sb24u. no pix or sound, power lite comes on about 10 seconds then power and opc lites alternate on and off. thanks RON


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.

The main power transistor in the power supply appears to have failed. It has also blown the fuse. Not a job for the DIY'er unless you have serious electronics experience.
