I have a 42 inch Insignia plasma tv. I only hook

First, I would check the connection to see if everything is in it's proper place and plugged in nice and snug.
Second, I'd try watching something else on the TV and see how it looks, I'd also try watching something using the same cable/input the DVD player is using. If that fails, try a different cable.
If your TV checks out, and it's your DVD player, it might be time to upgrade to Blu-Ray or buy a new DVD player.
Hope this helps, cheers.

The three picture cords (red/blue/green) often are a little larger around than the sound cords (red/white). If they are they same size, they are often grouped separate by picture and sound. Double check to verify if you have the "red" cords correct. Good luck.

Make sure your dvd player is not in progressive scan mode if your using a/v mode. The best way is RGB component input, provided you have the cables.

audio cables need to be hooked up as well not just a video cable.
usually red and white and clearly colored on the output side of the dvd player and the tv. input is on the tv output is on the dvd, also if you are using a fiber connection (optical sound) you will need a fiber cable from the dvd to the tv.

make sure you are using component video red green blue cables for video and not just the yellow composite video cable not sure if this helps you but good luck

if you connect composit video from your DVD player to the "Y" jack of the tv then you will get only a black and white picture .. the composit video out of your DVD has to be connected to the composit video input of the TV .. or if you have component outputs on your DVD then you can hook those up to the "three" component inputs of the tv .. (you have to have all three hooked up plus 2 audio cables ..

check using other player ..
to conform wether the tv line is clear...

well most lcd and plasma tv's above 36" will look grainy on standard definition because they are made for high definition so if you do not receive a high definition signal to your tv then that would most likely be the problem

Have you try to replace your HDMI cable?I recommend you to pick up a good Monster HD700 HDMI cable from a local retail store like best buy or circuit city.In case it isn't the cable problem,you could return it.
However,when you are a using the HDMI cable,it is normally either have both picture and sound or nothing at all.Are you sure you didn't hook up the audio OUTPUT from your TV back to a receiver input?
Or even an optical output from the TV to the receiver?

Hello Dollyer,
The first thing i need to know is how the TV is hook up. Do you have it hook up to HDMI, component, or just regular composite (Yellow, Red and White cables). This is very important info for me. What about your DVD player, do you still get a picture from that source. Please let me know

Best Regards
