Question about Sharp LC-15AV4U 15 in. LCD Television
TV is DEAD, NO Raster, NO Picture, NO SOUND, POWER IS OK, SIGNAL IS OK, THE POWER LIGHT FLASHES AND GOES OUT AFTER I PRESS THE POWER ON BUTTON, QUESTIONS- - DOES ANYONE HAVE A SCHEMTIC TO SHARE ? - WHAT COMMON FAULTS(COMPONETS)CAN CAUSE PROBLEM? THANKING YOU IN ADVANCE
Sounds like a lamp error.... either a defective or broken lamp within the LCD panel itself, or you have a bad inverter.

I took one in for repair with the same problem. Turned out to be a capacitor. (C431) near backlight transformers. Mylar 184 @ 250V. Replaced C407 also to prevent same problem.
