Sorry I didn't get back to you sooner. I'm still trying to figure out the best way to keep track of these posts. It gets a little confusing sometimes.
Have you tried a lower resolution from the source, such as 720p? Does it work then?
When it drops out, does it stay out? Or come back?
Let me know,
I've tried posting here before but can't find my last post on this problem??? I have an LNT4661F LCD TV that I bought just over a year ago and is out of warranty and when using it in any of the three HDMI ports the TV loses the signal to whatever device is used. I have tried updating firmware, using a different HDMI cable, used different HDMI devices such as Blue Ray players, PS3, Xbox and they all do it. If the TV is used in any mode that is not using an HDMI port it works fine, no problems. I have all devices setup for 1080P which the LNT4661 is capable of. When these same devices are used on another TV they work fine. Is anyone else out there experiencing the same loss of signal from ANY device hooked up to the Samsung LNT4661 LCD TV in HDMI mode? I'm tired of it dropping out on me in everything from a great part in a movie to being captured by a cop in GTA4. How about a shout from the infamous Mr. Samsung?
