Comcast digital cable on Samsung LN55C650: Is this normal with comcast digital cable (not HD) or something is wrong with TV?

Regular (NON HD) TV always looks awful on the big screen HD TVs. Upgrade yourself to high def and never go back.

I'm not sure on your tv but I just picked up a Samsung Combo HDTV/Monitor and had nasty issues getting the picture right until I stumbled across an easter egg in their setup. My Mac Mini is connected via a DVI -> HDMI cable to my Samsung. The colors were way off and it was obvious that the signal was not digital going to the monitor until I labeled my HDMI input "PC". That fixed the colors. Setting the option for "Overscan" fixed the resolution. Now I get a picture that looks as good as the DVI -> DVI input from my laptop.-- Chris

I have a cable modem and I occasionally have quality problems. I haven't figured out yet if the trouble is with my network, the player or Netflix. Sometimes I'll get a message saying that the connection is too poor to even connect, so I click OK, reconnect, and generally it loads at high quality. Or sometimes it will load at medium quality so I'll stop the playback so it will load again. More often than not it loads the second time at high quality. It's kind of quirky.I can't answer your question, but thought I'd share my experience. Oh, and I have a 46" Samsung tv.

I'm on my second cable box. Same problem on both, although the second box does get a better signal for the non-HD stations. Let me know how it goes.

Your tv must be able to take a digital signal across the composite feed though, it is not common and you should look it up in the manual

Thank you for your response. So when I get my HD box from Comcast, I should get one of their HD cables also. Right? Should I also get a Comcast HD cable instead of one from some other source to hook up my upconverting DVD player? Kinda takes some of the fun out of researching the world of HD plasma tvs. :-)

I am most definitely not the most advanced person when it comes to electronics knowledge I can only suggest maybe its a problem with your cable provider and not the tv itself?

I've had mine for almost six months and it happened couple of times. I've noticed that it never happens when I watch a DVD or Blu-Ray disk, or when I am streaming something either from Internet or my media server. It only happened when I was watching cable using my Comcast digital cable box. When it happens it goes black and comes quickly right back. Before it comes back it shows for a split second a sign that it is establishing HDMI connection. I was wondering if it has something to do with the cable box, but it is so rare that it is difficult to identify a pattern.

I have exaclty the same problem. I've had comcast at with this tv, and wide screen option was availabe at my old address (using HDMI cable) but at my new home, it's now grayed out. I believe it may have something to do with the comcast reciever. Can not find a FORMAT option on my cable box remote. It does have a position picture adjust option under the menu but that does not solve the issue as it just helps you move a slightly left ,right, up .or .down. I'm geting a 32 inch picture on a 53" TV. Totally SUCKS!Samsung forman suggested

sounds like it was subject to some digital coding comcast made a change recently too, all digital related basic cable users now have to rent a qam tuner I would call verizon tech support

Thanks! That makes sense. I did get a message that said something about HDCP. Can you recommend any HDMI cables that are HDCP compatible? I was trying to avoid spending a ton of money on one, but maybe I just have to. I also read on avsforum about firmware updates, etc. I guess I'll try a new cable before contacting Samsung.

Hey, I had the same problem with an LN55C650 and even with a new panel it did it. So the tech got on the phone and called and was told about the service bulletin and cut jumper number p854 on the 55" and that fixed it. So the new panel came back out but I got my tv fixed. Yay!!!

the unit has a tuner, but, it's not digital, please consult your owners manual. or, contact the manufacturer for other questions, possibly your cable provider could answer these questions more throughly also. my unit performs great....good luck with yours.

After checking all cables are correctly installed be sure you tell your TV where the signal is coming from. Example: On Samsung remote you have a 'source' button to select signal source//On LG you have an 'input' button to select source. If this doesn't solve the problem you may have a bad cable between TV/DVD. Swap cable with another and see if that cures the problem. Good Luck Susan.

HD is digital. Digital either works or it doesn't. It is not like analog signals where you can have varying levels of performance. If the HD picture is not breaking up then this signal booster should not give you an improved picture.

I've noticed it in SD (using Dish Network) but not in HD yet. I'm thinking it's because I'm just using the RCA that came with it, but even without the HDMI cables the picture is fantastic. Can't wait to see the HD and SD channels and Blu-Ray with the HDMIs

I personally have never seen this problem. I would ask you cable provider. When my time warner was first installed, the default setting was not 1080p. I had to manually set that up on my DVR.
