This isn't exactly a flicker problem, but I can't seem to the Hitachi thread, but I can really use your help. Hello, I am new to this forum and I am hoping someone can help guide me in the right direction. I have a Hitachi Plasma P50H401A and I received a Samsung BD-P1500 for Christmas, so I anxiously hook it up via the HDMI cable through the HDMI front input and...nothing. Then I try hooking it up via the HDMI 1 input and I disconnect the cable box I have had hooked up for a year with no problems and...nothing! So I finally try to hook it up using the provided composite cables and it works. So I try to eliminate any possible problems starting with the HDMI cable itself and the Blu-Ray works perfectly through a 19" Insignia TV. So its not the player, its not the cable and then I re-plug my cable box and...nothing! @#$#@! Now I lost the image via my cable box which was working fine. The only thing I noticed which may or may not have anything to do with the problem, when I press the INFO button on the plasma remote it states that the resolution is 480i, can this resolution have changed via some setting? If so, how do I get it back? Please help, thank you and happy holidays!
