This is my first post in this forum. I just bought Samsung LN40A550 40-Inch 1080p LCD HDTV. My tv is connected to DVR. Every time I watching HDTV and change channel (through my tv remote) cable connection disconnects and say Weak or no signal. I have to use TV remote and use source button to get back my cable.


Is this common when you are using HDTV tvs?

Are you changing channels on the DVR or directly on the TV? How do you have the two hooked together?


You may have better luck posting this in the LCD flat panel section also, this area isn't for display problems.

If I remember right this happened to me when I would switch from an HD channel to a SD channel when my DVR 4:3 overide setting was set to either 480i or 480p. If the 4:3 overide is set to "Off" this will not happen and the SD channels look a little better to me which is a bonus. I am using a Comcast Motorolla 3412 HD/DVR unit.


Anyway, this may or may not be your problem but it is an easy thing to try.


P.S. Your post makes it sort of sound like you are using the wrong remote to change cable channels...
