Question: Picture flickering

1. Check the input signal is normal, have without blinking.
2. Change the TV system.
3. The flickering picture on your TV may be caused by other electronic devices (cell phones, cordless phones, rotating fans, speakers, etc.) that are too close to the TV, or by devices plugged into the same circuit as the TV is connected in.

4. Try moving the offending devices further away from the TV.

If the suggestions above do not resolve your TV flickering problem, then most likely the backlight in your TV is failing and you will have to get your TV serviced.
