I have a Pioneer plasma display model pdp434-pu. No remote, no media receiver and no manual(which I did look up and read and it's VERY confusing to me). I'm just wanting to play my bluRay player. It has some kind of adaptor that screws in the 'white' plug in and makes it capable to plug HDMI into it but it only plays on part of the screen. Idk if the screen is messed up or from what I read on other sites it's not hooked up right. So I guess my question is do I need the media receiver to properly use the t.v.? And if so is it worth getting one or should I sell the t.v.? TIA
