I just hooked up my HD(H20-100) Direct Tv receiver to my Samsung 4095dx (1080p model) via HDMI. However when i turn the receiver on the video and audio on the tv go off and on every few seconds. I have tried the presets for 720p and 1080i and it happens both ways. I have tried connecting via hdmi1 and hdmi2 and the same thing happens. However when i hook up via component cables to the TV the hd works but i cannot get sound even though i have the optical cable plugged into the receiver and tv. I had this receiver hooked up to my projector(dtv tech installed) in the living room and everything worked fine(also via hdmi) 720p projector. This is the first time ive ever tried to use hdmi. Any suggestions? Im hoping that both my HDMI ports are not fubarred for whatever reason as ive never used them. I bought the TV new around Xmas time. Someone on the AVS forum said possibly upgrading my firmware on the receiver will help but im not sure what i need or how to do that. Any help is greatly appreciated. Another question, my roommate has the bill in his name, and they wanted a credit card for the install i had to pay $99+shipping for a total of $128 is this supposed to be credited back to the directv account? Im just wondering because my roommate did not tell me this and he is gonna cough up some cash if this is the case. Also they never shipped me the receiver the tech showed up with one new in a box.
