I just saw a thread on the 850 model and they are replacing a board for free, can this be my problem also? and how do I get the board replaced for free?
I have a new Samsung TV Model LN40A630M1fxza and Comcast cable with the DCH3614 cable box. Here's the problem, when I turn on the TV, I cannot change the channels or call up the TV guide with Comcast remote for about 2 minutes, the only thing that works is the volume control. If I use the controls on the Cable box I can change channels, . After the 2 minutes(Approx.) then the remote works fine. The cable company came and we were able to work the remote with the same cable box on another TV in my house with no problem and if the TV was Not turned ON we could change channels on the cable box. If I leave the TV ON and shut off the cable box and turn the cable box back on the remote works fine, but as soon as I turn off the TV the same thing happens I have to wait 2 minutes inorder to use the remote. Now here is the stranger thing I found out, if I Cover the TV with a Sheet( The left half of the TV has to be covered) the remote works fine. It seems like the TV is blocking the signal from the remote(Until the TV has been on for about the 2 min.)When I called Saamsung they said sorry we have no Idea and basically said I have to live with it. I'm hopping that as time goes it dosen't take longer until it never works..(And yes I unplugged the TV and Cable box to see if this would help and it didn't) Can you Help me on this..
