Last night I could not use my DVD player on my new tv. The TV could not find the DVD player. Rather than having HDMI / USB / Digital Sound, as jacks in the back of the tv, it has a Mini Connection HuB. It plugs into the back of the tv with a cable, and all of your ports sit in a little connection hub. Since HDMI 1 wasn't working, I tried a different DVD player into HDMI 1, and it still didn't work. Then I tried each in HDMI 2, 3, 4, and still didn't work. Tried a USB thumb drive into the USB port, and still didn't work. Replacement of this tiny little hub is $99. Finally I unplugged the TV for a minute, turned it back on and the Mini Connection Hub must have rebooted up and now works. I just want a tv that you turn on and it works. But I guess now you have to computer shoot it when ever it has a hic cup.... ugh...
