I have had a Sony KV-34HS420 HDTV for 18 months. I am now trying to use a Samsung DTB-H260F HD tuner to watch over the air HD. After trying two HDMI cables and 2 Samsung tuners the following problem still exists. When turning on the tuner and TV I have a perfect picture for 4-5 min then it changes to black and white including all the Samsung menus. If I shut off the tv for a few hours I get my color back for 4 mins and the again only black and white. After numerous permutations turning on and off tuner and tv it has to be the TV and specifically the HDMI connection as the component video connections work fine. So after 4 min of the TV on I can receive only black and white pictures on the HDMI conection.
Any ideas on how to fix this problem? I see I can buy a HDMI connection for this TV but don't know if it snaps in or is soldered in or is it a board and not the connection at all.
Thanks
