I got the 52" DILA last week. It is hooked up to the 8300HD Cablevision box via HDMI. The only problem I have is that sometimes on start up the screen is green. I found that by going to one of the HD channels clears it up immediately and it doesn't come back until next off-on cycle, and then not always. I have the HDMI connection on the tv set to "auto sense" as far as incoming resolution. Any ideas? Is this a tv or STB issue? Thanks.
