I have a Sharp Aquos TV Model #LC-60EQ10U. The remote control is not responding so I did the following: replaced batteries, unplugged TV, upgraded TV firmware, and bought a new remote control. Nothing seems to be working and I can't get the remote and TV to connect. I'm looking for any possible solutions I may have overlooked. There appears to be no external damage to the TV and the Infrared "eye". This problem happened quite suddenly. Prior to this, the remote control worked great. BTW: the TV still works great.
