Hitachi 55fx48b Is it gonna better quality if i hook up an HD box via Component Video connection to the tv.

No no no!
# 1. You need to connect all your components to your TV via an HDMI cable. For true HD and digital sound this is needed. Your TV (if its an HD TV) should have 3 or 4 HDMI inputs. So your Xbox/PS3 should be connected via HDMI cable. Your HD sat or cable box should also be connected with an HDMI cable. Same for your Blu Ray player.

#2. Now that your components are connect in a way which will enable you to see their media in either 720p, 1080i or 1080p your ready to get the Digital sound to your speakers. On the back of your TV you should (again on most all HD tv's) have a digital audio (optical) out. You need to purchase a digital (optical) audio cable and plug one end into your tv's digital audio out jack. Then plug the other end into your audio receivers digital audio in jack. You may have to go into your receivers menu to select or enable the digital/optical input. Then you should be rocking and rolling with true digital DTS, Pro Logic, Pro Logic 2 in either 5.1 or 7.1...

Think of your TV as the hub. Connect all the components with HDMI cables. And then your TV to your receiver with a digital/optical cable. It's that simple.

Never never use the red and white cables for audio. They were designed for 2 channel stereo sound. They won't deliver 5.1 or 7.1 digital sound.

Also... Don't ever hook up any component using the old "yellow" video cable if you want picture quality better than 480i resolution. They won't do HD period.

Here is a list of the popular video cables and they highest resolution.

Yellow video cables - 480i resolution

S video (super video) cable - 480p

Component video cables (red/blue/green) - up to 720p

HIgh definition multimedia interface HDMI - up to 1080p (full HD) and digital sound.

Hope this helps...

The TV is intended to be an end point of the video, not a source of audio. Many TV's (monitors) don't have ANY audio, much less surround sound capability. Composite Video is theminimalist video connection for setup; Component video to the TV should suffice for viewing DVD's.

Is your TV the SOURCE of surround sound programming (via an antenna) or does the programming come from elsewhere like a Cable Box? THAT would be the source you need to tap for surround sound.

Hello,
This indicates an Automatic Gain Control (AGC) problem often caused by a dried up capacitor. You will probably need a schematic to go much further. This could be a problem in the tuner, IF, or video amplifiers.

The following assumes you are sure the signal source is strong - try a VCR or other local one (channel 3/4, not the RCA jacks).

(From: Glenn Watkins ([email protected]).) Substitute a variable voltage source for the tuner's AGC voltage. Most of the time the range of AGC is from 1 to 7 volts. If you can get a decent snow free picture with an external AGC source, then the tuner is probably OK.

This is will require you to open the back cover of the television alongside an ohmmeter to read components on the printed circuit board of the television..
Take care

Is the satellite receiver HD or standard?
If it is standard you should hook up the box to the tv via RCA cables (Yellow/Red/White) and this will help with the picture quality.

If it is a HD receiver then hook up the box to the tv using a component video cable and this will drastically change the quality of the picture.

Using a coax cable to attach from the box to the tv essentially is connecting an analog signal to the tv and this will produce a lower quality picture...

Good Luck!!

The way you have it hooked up right now will not work unless you have a coaxial out on your cable box going to the dvd recorder. Even then, picture quality will be severely degraded. The best way to do it is to leave your cable box hooked up to your TV via HDMI and connect your dvd recorder to your cable box via component video if your dvd recorder has a component video input. If it doesn't, then just use the composite video input. That way your picture quality will be better and you will still be able to record with the TV off.

I found that since the Panasonic TH50PZ80U TV has only 2 HDMI ports on the back of the TV, the best solution for me was to use component (red, blue, green) cables to connect the Home Theatre to the TV. I suppose I/you could connect the home theatre to the HDMI port on the front panel, but I don't want cables hanging out the front of the TV (personal preference). Unfortunately, I am no longer able to use the VIERA Link functionality available by connecting all Panasonic components to each other using HDMI cables, but I feel it's a small price to pay for the incredible picture quality acheived by using the HDMI cable to connect the HD Cable Box to the TV. I may yet be able to control everything using the HD Cable Box remote, but I haven't gotten that far yet but I've got Comcast coming on Saturday and hopefully they can let me know if this is possible: let me know if you have a solution.

So here are the components and the cable types used to connect:

1. HD Cable Box to TV: HDMI cable & Optical Audio cable
2. Home Theatre to TV: Red, Blue & Green component cables
3. BluRay Player to TV: HDMI cable

I hope this helps someone else.

TV is HD correct? Use the Y/CB/CR from the Sat to the TV. Use the Digital optical cable for sound from the sat to the receiver. Use the s-video from the dvd player to the tv and the l/r to the receiver for sound. I would suggest upgrading to another set of Y/CB/CR cables to connect your dvd to the TV and benefit from better picture. Also, buy another optical cable for dvd sound (so you can enjoy surround sound). Your receiver has two optical inputs so youre covered there.

Yes! You can pass the video signal through the receiver. This is most useful when you have more than one video device (e.g. DVD, cable box, VCR,...), and you can use the receiver to switch to the audio and video for the selected source at the same time.

On the back of your Onkyo HT-SR800 there is a section labeled "Component Video." It has three inputs and one output. So, attach your DVD by component cables to the "DVD In" and then attach component cables from the "OUT" receiver connection to the TV.

If your TV doesn't have a component connection, then this addresses your other question. You can't gain anything with this, because your TV doesn't support it. Connect the DVD to the TV according to the highest quality connection that they both support, in this order: composite, S-Video, component.

If you are using composite, but they both handle composite, than yes, you will get a better picture by going to component (or even S-Video). If both devices support progressive scan, this could be a substantial difference.

Your receiver accepts component, s-video and component video, but keep in mind, it may not do "video switching." So if you connect the DVD in via component, but go out to the TV over composite, then you may not get any video at all (but feel free to try). Try to avoid this, but you may be forced to try depending on the limitations of the various devices that you are hooking up.

YOU MAY NOT HAVE THE HD COMPONENT CABLES AND CONNECT THEM TO ONE OF THE VIDEO LINES..
