I have a E55OVL Vizio that I had lost the sound on all three HDMI ports. Got a new main card through a supplier from Vizio. This is suppose to be a brand new card not rebuilt. Anyway the TV works fine now sound and everything. The problem is now the remote does not work were it worked fine before. I just use this remote to switch imputes for when I want to used my DVD Player. I put new Batteries in it and even tried a different remote for a 42" Vizio. Nothing works the TV. I'm hooked up to Direct-TV. All of the side buttons on the TV work fine but would rather have the remote working. Any help? Dennis
