Set up a Samsung 6800 series TV today with a 10–12 year old system using component video. The old dvd looked very poor in interlaced mode, but when I set it to progressive mode the screen went blank.



It was going through a 10-year-old Integra receiver, so I pulled it from the Integra and made it a straight shot from DVD to monitor. No change.

That TV should accept even 1080p on component. AFAIK, all analog restrictions are on the source side. If there's a cable box on site, try 720p component on that same input.

It shouldn't- I know it sounds like I'm saying you're not careful, but look at the cables and make sure the red and blue aren't reversed. I just found that on my ReQuest and I always use the red Planet Waves cable with text for Red, the White for Blue and Yellow as Green. That obviously didn't matter when I connected it, but when I rewired everything last week, I found the problem with my component video.

While you're at it, connect ONLY the green input to the green and see if it comes back. Or, connect the end to the composite out of the DVD and see if you get video. If you do, repeat with the other two, to verify that they're good.

I know you gave us the series number, but... is that a TV with one set of inputs that can either be component, or you can plug composite into the jack used for the Y of the component signal? If so, that's completely weird!


That gives you a high resolution image with totally screwed up colors.


You found the problem... what was the symptom for which you found the problem?

Sounds like you were using the audio part of a VCR cable to pass green and blue. This should not matter, but those cables could have poor enough high frequency response to muck with the detail of the picture and the clarity of color transitions.


Recently I found with a Samsung TV that green only did not give me black and white, as it has in the past! I got green and red when I connected green and red, and green and blue when I connected green and blue, but no black and white from the Y signal.


Be sure your monitor will respond to 480i when you do this. This doesn't always work with a higher resolution display input.


Yes, of course.

When the Red and Blue were crossed, I had no video at all. I have seen the screwed up video with one of these two was bad/disconnected, but when they're crossed, I usually see nothing.

When I connected everything, I used cables that were laying around and when I found the problem, I was changing cables so they were as short as possible. Once I found that I had no video, I just grabbed a DVI-HDMI adapter and ran that into the Denon and it worked, so I really didn't give it any more thought. Then, I was troubleshooting a client's Mac G4 and needed a DVI-HDMI adapter and didn't feel like going out to the van, so I used the one I had up here. Since the Denon up-converts, I don't need the DVI adapter and when I was reconnecting everything, I was making sure all of my sources work and I was just about to re-terminate the component cable when I found my screw-up.

I have never seen B&W when only connecting the green- I have only seen green tint. If the green is omitted, the video SHOULD stop. On some new TVs, the Green doubles as the Composite input- I don't mind that, really. Well, unless I actually need the extra inputs.

If the monitor is set to Auto for resolution, using a low res source should cause no problems.

Wow, that's completely different from my experience, but I haven't played with any of these, except for the one I mentioned, with any TVs since they have started having just one combined composite and component input, sharing the Y jack.

I'd learned that the Y alone gave a black and white image because Y is an intensity signal. Blue has blue minus green, and combined with Y gives blue and green; red has red minus green and combined with Y gives red and green. (Something about those reasons is not totally correct but I don't see my mistake, and those are the results I've seen for at least ten years!)

I've NEVER seen crossed red and blue give no image. It's always screwed up colors.

I've run into some samsung TVs a while ago that would not do 480P Component.

FWIW, the video signal recorded on a DVD is already progressively scanned and as soon as the pickup sensor reads it it is immediately interlaced.

If you output an interlaced signal and let the TV deinterlace it you ostensibly get a better picture as you are removing another layer of signal processing in a cheap DVD player. TV scalers are pretty good these days.

Green has the synch signal, and that's why the video disappears or is completely distorted when that cable is bad, or omitted.

I did an install last summer that included an old Satellite receiver, an older Denon receiver, a used Sony DVD player and an oddball Plasma TV. When I connected the HDMI to the HD input, I had two images, separated by a vertical magenta band. When I used the component input, it was fine. I really prefer connecting the sources to the AVR and then run one cable to the TV- it solves so many problems (as long as CEC is disabled), but when no questions are asked by the seller, this is what you get- cobbled-together crap.

The guy had gone to a local store that was having a 50% off sale on used equipment and the dealer has never been great at qualifying customers, so he sold the guy a receiver that was over 10 years old LAST YEAR. In theory, it should have worked fine with the old TV, but then, the guy couldn't figure out what buttons to press in order to switch from one source to another, so I set him up with a cheap Harmony remote. It works, he doesn't need to type War And Peace in order to operate the system and the cheat sheet seems to be working for him and his daughter.

In this case, the picture looked like there was a screen door in front of it. Completely unacceptable.



That is what I was wondering. Thank you.
