i recently had at&t uverse installed at my home. whenever i turn on the samsung pn50c550 i get a searching for signal & then a no signal detected box on the screen. if i unplug the hdmi cable & plug it right back in the same, or into another hdmi port the picture comes up. all the lights on at&t box are lit up, i've swapped hdmi cables. still same problem. i've looked at all the settings on the tv menu, but nothing jumps out at pertaining to this. any. i have two more at&t hd boxes & no problems with them.

Why isn't this ATT box suspect?

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
