Analog video into Digital TV ??

[esteveW]

Over the last 6 month (off and on) I have been working on getting a good/useable signal and picture on my TV from my BUD(s). I'm testing my second one now, a 9ft solid. I have tired several LNBs and feed horn.

Through all this I have been sending the video to my HD digital TV. In addition to the HDMI and S-Video, it has three A/V inputs that are selectable from the remote. I also had a VHF input as well but I haven't figured how to utilize that yet.

I have been using one or two of the A/V inputs and get sound and a clear black and white picture. The picture is often out of frame or out of sync. I have been blaming this on feed horn orientation or inproper tuning of the verious receivers I have used.

Today I took a ordinary TV off my sailboat and hooked everything into it and WALLA, I have color and very stable picture.

I can only conclude that the HD tv can't handle the analog video and if it is, the color and sync signal is stripped.

Any opinions??

What receiver?
My Toshiba TRX-1420 analog receiver is through the A/V inputs on my HDTV and it works fine....not that there is much on analog

I feel your pain:

. . . but mine works fine.

Two things come to mind:
- bad A/V cable
- plugging into your [ame="http://en.wikipedia.org/wiki/Component_video"]Component video - Wikipedia, the free encyclopedia@@AMEPARAM@@/wiki/File:Question_book-new.svg" class="image"><img alt="Question book-new.svg" src="http://upload.wikimedia.org/wikipedia/en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png"@@AMEPARAM@@en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png[/ame] on the TV, with composite signals.

- plugging into your Component inputs on the TV, with composite signals.

Assuming that the OP used the same cable to the regular TV, I think your "component input" theory makes the most sense. Particularly if the user tends to be a little color blind like I am. The video from most C-band receivers will go into a YELLOW RCA plug, but I often have a hard time seeing the color on those plugs, and can see how it would be easy to make a mistake. It also seems a little unusual for a modern HDTV to have 3 composite inputs. My TV has 2 HDMI, 2 Component, and 2 Composite, and I had to shop around to make sure that I got a TV that had that many composite inputs, as I really needed more. I don't remember seeing an HDTV with 3 composite inputs.
Anyway, yeah, I'll bet that you're right, that the OP was using a component input instead of a composite.

Ok. I think I'm beginning to "get the picture". I'm mixing Composite and Component video.

I just got out the manual on the Sanyo HT30746 TV.

I have:

HDMI <<- connected to my D**h box since it is digital signal.

INPUT-1 (w/S-video) <<- connected to ViewSat DVR 7000

INPUT-2 (R&L/video) <<- attempting to connect to various analog FTA receivers.

INPUT-3 (R&L/video) <<- attempting to connect to various analog FTA receivers.

I pull the Sanyo out of it's cabinet and found I was hooking the white connector to the mono audio plug and the yellow to the "Y" video (not understanding the meaning of"Pr", "Pb" or "Y"..)

So, "There in lies the Problem". I can only use the Input-1 for the FTA receivers, unless they have a COMPONENT video out put.

Here is a possibility--- I think the ViewSat 7000 has a COMPONENT output and I could put it on Video 2 or 3. That would free up Video 1 for my older analog boxes.

Thanks for getting me to recognize the difference between COMPONENT and COMPOSITE video.

Now to unscramble the tangle behind the Sanyo.

Sounds like my setup on the TV....
2 sets of a/v plugs
2 sets of component plugs
2 HDMI cables

and trying to get everything hooked up properly

Component vs Composite:

Yea, I recognized the no-sync , B&W picture, and wrong-color problems as something I'd done. -
Luckily, my Syntax 542 LCD has two of each kind of input . . .
- S-video
- Composite
- Component
Plus one each VGA, DVI, Tuner, and a single HDMI. (10 total)
Most all my SD FTA receivers have three types of output . . .
- S-video
- Composite
- Component
So, you have a lot of flexibility in how you interconnect things.

It was that single HDMI connector that put me in the corner, and I described a solution in your other thread.

edit:
If you need more cables, take a tour through MonoPrice web site for some good bargains.

My new Aquos has every input I need now and ones for future upgrades.

The only inputs on a digital tv that are digital is HDMI, DVI, VGA and RGB (TTL). Composite, S and Component are all analog.

HDMI and DVI-D are digital.

Analog
======
Composite (Yellow-V/White-L/Red-R)
S-Video   (4-pin DIN connector)
Component (Green-V/Blue-V/Red-V/White-L/Red-R)
DVI-A     (4 round pins around the flat-wide pin to the side of the mass of 18/24 pins)
VGA       (3x5 pins)
RGB in all it's various forms

Confused yet? I was

 

[tvropro]

Ya I should have said DVI-D, DVI-A is like component.

 

[meinename]

DVI-A is RGB like VGA in all of the cases I've run into
Component is YPbPr (mostly)

Most DVI connections are DVI-D but since it got brought up it needed to be distinguished from DVI-A since it's possible too but analog.
