Hi,
I have had this Samsung LCD/HDTV since October 2008, it was manufactured in August of 2008. I really never had any issues with this problem until about a month ago.

We could be sitting watching TV and then the picture(video) would totally black out from 5 to 10 seconds, but the sound would stay on.

I have the TV connected Via HDMI to an AVR Yamaha RX-V665

This happens about five times per hour.
I called the Time-Warner cable peeps and they told me to call Samsung to come over and troubleshoot the TV and the electrics. I also went to the Samsung download page for this model TV, and I did see a firmware update to address this same issue,so I updated, and it still is doing the blackout thing. I just went to Time Warner yesterday to exchange the HD-DVR and remote for another,hooked it up, and it still has this problem. Time-Warner told me that if the TV is on all day long, then maybe it would be wise to turn off the TV every four to five hours for an hour before turning it back on.

Anyone else has this same problem, and how did you deal with it? Thanks!


About LCD Cleaners...I called Samsung to ask what was the best cleaner they recommend, they told me "Screen Clean". I had bought a "Dust Off" brand called "Monitor Wipes", but that leaves a residue on my tv and viewsonic LCD screen.

Does this occur on all inputs?

I'd say if the TV does it on all inputs and you've tried a different electrical outlet (big long shot if you're still getting sound) then calling a Samsung tech would be the next logical step. I wouldn't wait too long because you're still covered under warranty. I suspect it has something to do with the electronics.

Time-Warner told me that if the TV is on all day long, then maybe it would be wise to turn off the TV every four to five hours for an hour before turning it back on.

That is probably not horrible advice, but still nonsense. Your Samsung manual should cover tips for turning your LCD on and off properly with heavy use.

The best cleaner I have ever used for televisions (or the inside of car windows where you absolutely can't have streaks) is called Sprayway. Use it with an old (clean) rag or paper towel and it will remove everything without damaging coatings. It will not leave a residue and will even clean the ones left by other cleaners. I have used it on just about every kind of delicate plastic you can think of without any problems. Just remember that using a paper towel or rag can leave cotton particles embedded in your LCD screen if you have a matte finish. That's why it's a good idea that to use an old rag that has been washed dozens of times or an old 100% cotton T-shirt. I suggest spraying it into the rag instead of spraying it directly on the TV.

The product looks like this



or this (new version of the can)

No problems after replacing another DVR box

Ok.
After replacing about four DVR boxes from Time-Warner cable,I had yet another tech come out from TW, and he noticed that the outside Cable was going into a GE power surge protector,then out to the Cable box. he said the signal was good at the Cable box, but somehow the signal was screwey. He disconnected both the IN/OUT cable coaxials from the GE Surge protector,and had it go directly into the STB cable box, replaced the DVR box,and I have not had any issues at all!
