Re: Sharp Aquos LC-60LE652E - Blank screen, no sound, steady blue LED
Hey dick,
12V is within the operating voltage range for those IC's
What voltage do you have on Pin 2 of each of them which should be >2V
I measure +4,68V
I would check all the mosfets/diodes around those IC's. The 4 above and the 4 below the IC's
see attachement
I'm not realy sure, if the mosfet's are defect, but normally there should be overload between Source and Gate, isn't it?
