I just bought the JVC LCD TV 1080p HDTV and it is only showing black and white. I have tried adjusting the sittings but nothing seems to work and the manual is useless. I'm short of taking it back for a refund...

If you have parallel horizontal black lines on a white background, you can see the separation between the lines when it is viewed at close range (Figure 1). As you view the lines from further and further away,the image gets smaller, you eventually get to the point where you can no longer see the separation between the lines, and it looks like one line. Losing the ability to see separation in the lines is exactly what happens when you sit too far back from an HDTV set. If we apply the same principle to an HDTV, a 1080p resolution HDTV has to fit 1920 vertical and 1080 and horizontal black lines separated by the white space on the screen, (that is the pixel grid of a 1080p HDTV display). Furthermore the spaces between each cell of the grid need to be very small in relation to the area each cell occupies, or you will get a screen door type effect. A bigger HDTV can increase the size of the cells and the separation between the cells, so everything doesn't run together when you sit further back.
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.
You have to option in LCD Source In-Put.All LCD Have this In-Put Com posit-Yellow/Red/White (AV) In LCD Select AV Mode After That Connect Yellow /Red/White as per color pin given in your LCD. Component-Green/Blue/Red If you have Component in put in your LCD than select from source component mode for Red/Blue/Green.
you have lost your chroma (color) circuit the sepia you are seeing is just the black & white picture black and, white is adjustable from red to blue to green tint so; your sepia is an overloaded red circuit i could fix this but, i'm here and, you're there so take it to a serviceman it should not cost much more than $100
Thin white dashes on top of screen is PERFECTLY NORMAL. It is nothing wrong with the TV, it is the broadcast. What you are seeing is the very bottom of the timecode running. It doesn't happen all of the time or all channels. It usually happens with old 4:3 commercials predating "Digital TV." This is mentioned in your Users Manual. You should be able to adjust the horizontal/vertical position in the menu settings.
