I connected my tv and my dvd player the sceen is flashing blue.. whats the problem

Does the TV have an HDMI port on the back of the TV? Example: DVD player HDMI out to TV HDMI in. then on the TV select input and choose the HDMI port number you connected the cable to on the TV

Replace the "non-High-Definition" TV with a newer one, with H.D. inputs (to match the H.D. outputs from your new DVD-player).

i have a rca dvd and vcr drc8335 its locked on hello it keeps saying hello over and over

Try posting the question in another area as this deals with TV sets like in the home......

Have you tried using standard RCA AV cables? yellow-red-white - to TV. Or have you tried using an S-Video cable (a 5-pin mini DIN plug) between your DVD player and TV? if your TV has S-Video input, and your player has S-Video output, a cable for this should be easy to obtain and connect. Not expensive either.

Your TV should automatically detect the connection of S-Video (if it has this feature). S-Video is better quality than standard RCA yellow AV cable. (you can leave the existing component video connected)

You can also check your DVD player 'setup' maybe it is incorrect - make sure when using component video (red-green-blue) to set the player's output to progressive (for a TV that supports it) - unless it is already set to this.

If everything in the setup menu checks out OK, go with the cheap and easy S-Video cable suggestion. Radio Shack may sell these.

you need to hook the dvd recorder up to the dish net work, yellow to yellow port, red to red port, and white to white port.
the dvd recorder should have had a book in with it to show you how to hook it up

If your TV has the green, blue, red inputs then connect these 3 cables for the picture. DVD to TV, green to green, blue to blue and red to red. If your TV only has a yellow input, then connect the green cable only from the DVD yellow to the TV yellow. Now for the sound. Connect the DVD white to the TV white. Connect the DVD red to the TV red with the red cable. The white and red inputs will be next to the yellow and the green, blue, red inputs on the TV. Next select the TV input using your TV remote. Select the input for the DVD connection.

Turn on your DVD player, go to your set up button on the DVD remote, go to TV and select p-scan. It fixed my problem. My screen was all blue before I did that. Hope it works

It sounds connections are not matched yet. Make sure connections are green to green, red to red and blue to blue in dvd player and tv are correct.
Try another component video cable.
If problem still exist, test dvd player to any other tv, found ok then component input of this TV is bad, need to get it repaired.

Remove & re-seat the component video cables at both the TV and the DVD player.

If the problem continues, disconnect BOTH ends of the BLUE cable and the RED cable. Connect the BLUE cable to the RED jack at both the DVD and TV, and connect the RED cable to the BLUE jack ob both the TV and DVD. If the RED color comes back and the BLUE is missing, then replace the RED cable (the red cable is broken and will not pass the signal that it is connected to).

If all works, reconnect the colored cables to the corresponding colored jacks at both the TV and DVD player.

If the RED color still won't display, isolate the trouble to either the DVD player or TV by connecting the DVD to another TV w/ component jacks. If the RED is still missing, it is a problem inside the DVD player - if the RED displays, it is a problem with the TV.

Good luck!
