Simple Techniques to Fix Sharp TV White Light Blinking
Follow these solutions in the given order to rectify the white light blinking issue on a Sharp TV.
Power Cycle the Sharp TV
If you get a flashing white light on the Sharp TV, the first thing you have to do is to power cycle the TV. Start by switching off your TV and then unplugging the cable from the power outlet. Now, long press the Power button of the Sharp TV for 20-30 seconds to diffuse the remaining charges. Wait for a few minutes, replug the cable and turn on the Sharp TV. Then, check whether the white flash light has stopped blinking.
Check the Power Supply
Ensure the TV is plugged into a stable power source. Fluctuations in the power supply or a faulty power grid can lead to blinking light issues. Try plugging the TV cord into a different socket to check it has been fixed. Avoid using a surge protector to connect the Sharp TV to a power source to avoid voltage drop. If you still see a white flashing light, try the next troubleshooting method.
Inspect Cable Connections
Check whether the external cable connections are connected properly. If not, ensure the HDMI or AV cable is plugged into the corresponding ports. An improper connection or damaged cable will cause the Sharp TV to blink a white light. Ensure the cable connections are firmly connected. If a cable is damaged, replace it with a brand-new one. If the flashlight problem doesn’t get fixed, move on to the next troubleshooting method.
