Sharp
LC-65Q7300U
<p>
TV boots to Sharp logo, then shutdown, then cycles again. I suspected backlights. Opened up and removed backlight connector, power on, same symptoms. Voltage out of power supply to backlights test OK and follow with bootloop up/down.
Used LED tester into backlight connector, one set of pins test OK, one set test Open. But, with the backlights disconnected the TV is still in a bootloop. So aside from a possible bad LED strip... Could I also have a firmware issue?
