Can not see the Video when I input it, see only a blue screen.

Blue screen is an indication of missing video signal input. Check all of your input video connections for any loose or broken wire/connectors.

The video may be plugged into input 1 and the audio into input 2. This could be a million different things.
If using Component video (green, blue, red, RCA cables) check to be sure the Green cable is set all the way on both sides. The green cable sends the sync and without it you will have NO picture.

Hello sir, hi, please check the video cable. If you are using the three color audio/video cable, the yellow one goes to the yellow input of the TV to the yellow output of the DVD recorder. Then check the TVs audio video settings, the TV should be in the video channel, if there are several video channel, check where the video is coming in. Make sure that the yellow cable is good. you can swap several cables to check.
If your TV is component input, put the red green and blue wires to their respective color port, one end is on the DVD recorder, and the other on the TV. make sure your cables are good. Do the same thing with the S-video and HDMI cable. if your TV has this.

Make sure your tv is on the right input first of all. The newer flat panel lcds combine the componenent video (red , blue, green) with the composite video and audio (yellow, red, white). If your tv is on the component input then you hear audio from the composite input since the audio inputs (red, white) are shared. Look for a source or tv input button on your remote or the tv itself and try pressing this button unti you see a picture with sound.

You need to also connect the RCA audio out (red/white) from your source to the audio input on the TV. You do not need the yellow wire as that is for composite video. The component cable (red/green/blue) is only for video. Look at the input on the TV where you connected the red/green/blue cable. Right next to it, you should have another red and white connectors for the audio input. Connect that to the audio out on the cable box.

If the Visio TV has more than one input, don't forget to use its remote to make sure the correct input is selected. It probably wouldn't hurt to put a DVD into the player, confirm its running from the front panel counters) and let it keep running as you troubleshoot. At least then you'll know there is an active video source once you find it. Another thing you can try is to put in a music CD, if the player accepts these too (most do). Then when you get the TV set to the right input, at least you'll hear music, and can then go back to trying a DVD.

I know you're using component video, so remember that unlike HDMI devices, the TV is unable to switch to the correct source automatically. So it may just be that you've never had to switch the TV's input source before. Good luck! :-)

Have the exact same problem, opened a case file with Hitachi.

I have a feeling it's a firmware problem -- hopefully they will make my life easy and mail me the proper cable I can connect from PC to TV, and the software to run such an upgrade (as opposed to packing this big thing up and carting it off to a service center).

I'll post my experiences.

maybe, try replacing the IC

Do you hear sound? if you dont then the TVs not set to the proper input or channel . Is the VCR hooked up the way it always was or did you just install it? If you didnt then if you here sound then the heads are dirty or theres a problem in the video section of the VCR answer these few questions and Im sure we can get this thing going or at least find out the problem.

My panasonic Tv pic suddenly turned into a blue color I can't see the pic any more just can hear the audio.....any solutions????
