My HDMI connector on the back of the tv is not working. I lose picture and have sound. sometimes I can wiggle the HDMI cable and it will come on for about 3 seconds then green screen then black screen with just sound. I've replaced the HDMI cable but have the same problem. It appears to be the connector. any ideas on how to fix this or cost to fix this? looks like it is one unit that includes the coax connections as well.

Hi, you have one of two problems, either the color wheel is going or one of the cooling fans are going, the color wheels are a very common problem in samsung dlp`s, sorry I can`t nail it to a specific part but I`d bet it`s the color wheel as they are notorious for failing in samsungs, video-tek
