Re: Sharp LC-60SQ15U TV DPS-167CP - No power
WHY? because if that feedback winding is open circuit you will not get the boosted vcc voltage to make the ic work.
Look at the schematic, It's pins for this winding are 1&4, on your board they are 5&4, pin 4 is ground, pin 5 connects to D7906 and the 3 parallel resistors
