Good morning. This TV acts like a 'dimmer switch' at times. The picture fades darker, then it will come back normal. Then it will go brighter. It does it on Video inputs and RF and is not constant. I do not use the HDMI or components. Any idea of what I could do to repair?
This is using either Dish Network receiver or DVD & even VCR tapes. It happens with DVR or Live television on the Dish Network. However, when viewing the DVR or Dish Live in other rooms, the fading does not occur. This leads me to believe it is the TV.
