I have two Sharp LC-26SB14u TVS. One is hooked up to a Dish Network HD receiver. The other is hooked up to a HD DVR receiver. Both are hooked up to the same Phillips DVD player (DVP5992). The TV hooked up to the HD DVR can view all four different view modes- side bars, s.stretch, zoom and stretch. On the other TV, hooked to the regular HD receiver, I can only access two of the view modes- stretch and zoom. When I purchased both these TVs, I could access all four view modes on both TVs. Is there a way that I could reset the one TV in order to get the capability of all four view modes?
