Common problems with Sharp Aquos TVs include a failure to power on, flashing green lights, flickering screens and the presence of green and white lines on the screen. Other problems include random powering on and off, blinking power lights and the failure to produce pictures or sound.
A blown fuse or defective main power transistor in the power supply can cause a Sharp Aquos TV to not power on when the standby light is blinking. In addition, a faulty inverter, worn-out release button or failure to reset a Sharp Aquos TV can result in a blinking green light when the TV is turned on.
A worn-out jumper on the power supply can cause the screen to flicker, whereas vertical lines on the screen may occur when the timing controller is faulty or when the control board is worn out. Outdated firmware or a program glitch in the factory settings can cause the TV to turn on or off randomly.
A worn-out fuse or incorrect settings in the input channel can cause the Sharp Aquos TV to not display pictures when switched on. If the TV is not producing sound, this could be due to a lack of power supply or the mute button being activated. Resetting the TV incorrectly can cause the power light to blink continuously.
