Question about Sharp Televison & Video
My Sharp LC58Q7330U does not stay on. The standby light blinks twice red then shuts off (I can see the startup picture by shining a light through the back where the backlight wires run.) I put a MM on the wires and seen high voltage during startup, but drops steadily down to 0 volts when trying to power on. Should I be looking to replace the powerboard or backlight...or? I dont want to take apart till parts are order and job is to be done
