Thanks in advance for reading this post.
One day, I was chanign the channels on the tv, when all of a sudden i changed it to a random channel, 400 or something. Then, the remote froze temporarily, and the box on teh top right of the screen displays "HMC" with HDMI 2 underneath. Usually it says HMDI 2 on top and bottom of the box in the upper corner. I rest the DirecTV box, and when I turn i ton, the tv beging to work for 2 seconds before switchign to HMC mode. In HMC mode, the screen kind of dims and lights up. It's very strange and I feel hopeless about fixing it.Le tme know if anyone has any suggestions! Thanks again!
