My Samsung LED is 21 months old. As of tonight I have sound, but no picture. I am out of warranty as I did not pay for extended years. There is evidence of a glow on start up. Based on previous posts, I am trying a hard reboot tonight and running the air conditioner over night. Any other suggestions for trouble shooting?
So, after powering down for 10 hrs and running the air conditioner, my Samsung still doesnt have a picture. On powering up the screen lights up then goes dim, then black. I still have sound, but picture did not return. What would my next trouble shooting step be? Thanks.
