Question about Hitachi 50V720 Television

1 Answer

"No Sync Signal" on both component inputs

Both component inputs produce no picture. I have cable and a 360 hooked up which worked fine for a long time then stopped. I tested the cables on another television and the picture came through fine. The HDMI input works, the AV input works, but not the component. Is it possible to wearout the inputs? Is the a internal computer problem? I'm at a loss. Please help!

Right now there seems to be many people with the same TV problems with sony and HDMI cables. Most of the solutions are resetting the TV and sony product. Try leaving your TV unplugged for a hour to let it reset itself.

I have a daenyx lcd tv, model DN-15, input 12VDC-4A and am trying to hook it up to an xbox 360 console.


If you are using the Red/Yellow/White cable, that's composite cable, but if you're using the one that's Red/Yellow/White/Blue/Green, that's called component. So basically, you set your TV's input to the corresponding color match. 5 colors: Component, 3 colors: Composite.

No input signal VGA/Xbox


You are doing nothing wrong. The best thing to do, which you are doing, is to eliminate possible problems. Try a different cable, monitor etc until you narrow the problem down to a single component.

Video Issue with Onkyo 606 when trying to watch Cable TV.


When this happens and you just see the input label try to press the power button on the front of the cable box and see if it brings the picture up. If this does produce the picture then it is a good possibility that something is interfering with the remote communicating with the cable box. I don't know if you have it contained in an entertainment center or how you have placed your equipment but if there is glass try to clean it and also wipe down the front of the cable box and make sure there is an unobstructed view of the front of the cable box.
Good Luck.

Plays dvds on xbox 360 fine, but no picture for games/dashboard


already solved it. thanks. i couldn't see the xbox settings blade because of the blank screen so switched my component cable to the tv setting instead of the hdtv setting, then i could see the dashboard in non-hd and switched the resolution to 720p while simultaneously switching the component cable back to the hdtv setting. that worked.

No Picture, Only sound


You need to tell the PS3 that you are now using the new video method. It is still trying to output video on the yellow cable, not the component. If you go to settings>video and tell it to use component, and then switch the cables real quick, it should work.

An easier solution is to do a backup from the system menu, then a "restore" (quick restore is fine), and then power it off, hook up the new cable, and it will detect the video method when it turns on for the "first" time (since the restore).

You do have component input on your TV, and that is the input you are on when you are trying this, yes?

No Picture from Component Input #1 or #2 but do have audio via Surrond Sound


Simplest thing would be that your component cables are not HU'd correctly. Having them reversed would do this.
