Hi, Flat panel television instruction manuals are not very easy reading material, there are many connections on the back-you need to plug in some sort of input-always coming from the " out to T.V." of another device. Cable coax's are most common-the cables aren't very flexible that's one way to tell them apart from an RCA cable-usually with red, white, yellow,green and blue colored ends. The red, white and yellows are what we'll focus on for now-the yellow's are for a picture-connect them from an " out to TV" to " video input" on the back of tv, then for sound likewise- red and white colored from an"audio out " to "audio in " if coming from a VCR-you may use the rather un-flexible " screw on" coax connector-same if coming from a satellite/cable box-some satellites require tuning tv channel to # 60 for a picture-other wise it's channel 3 or 4. although you will get a better picture using yellow, red & white rca cords. I hope this has been of some help, prodzilla

I have no color on my Samsung Flatscreen TV


This means absolutely no color - equivalent to a black and white picture. Not even a hint of color.

First, confirm that the source is actually in color - try another channel or input device.

Next, check the settings of the color control - it may have accidentally been turned down. If your TV has some kind of automatic picture mode, try turning if off and adjusting the color control. Try adjusting fine tuning if you have such a control and the problem is with a broadcast or cable transmission.

At this point with a confirmed color signal source, there is a problem with the chroma circuitry.

Note that to the average person, the obvious question becomes: is my color picture tube bad? The answer is a definitive NO. It is virtually impossible for a defective CRT to cause a total loss of color. A defective CRT can cause a lack of a primary color - R, G, or, B or a short between two colors which will mess up the color but is not likely to result in a black and white picture.

Some possibilities in no particular order:

Weak signal or defect in tuner/IF causing loss of signal strength.

Coler killer set too high (internal control) if it has one.

Defective part around the chroma chip/circuit. Faulty color oscillator.

Bad connections in area of chroma chip/circuit.

Defective chroma chip (don't suspect this first just because it is probably very expensive).

Try prodding the main board around the chroma chip with an insulated tool to see if you can make the color come and go.

I had one set where a $.02 resistor decided to open up causing just this problem - perfect BW picture, no color. Another had a coil with a broken wire.

My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the's something else..don't know you?

Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here

Blurry and colors are seperated red green white

if you are viewing from a projection tv, chances are you have to go thru the menu of the tv to 'picture tuning'. here it gives you different things that could be fixed. one to look for is 'lamp alignment'. It should show all the colors and lines with directions to bring them into focus. This should fix the blurriness and 3-d red/green/white separations. hope this helps you!

Screen looks like a picture negative, PIP works fine, sound fine

Sony's have dual tuning systems to allow for the separate PIP channel. The common problem on the Sony's is the circuit board and tuning module connections go bad. It is likely that the connections on the board or module were already in the decayed process and moving it just accelerated the issues that were inevitable.

The quick fix is to swap the PIP over to the main picture or to bus the antennae signal to the antennae B terminal thus bypassing the bad tuner module.

The recommended fix action is to have someone with soldering skills to remove the chassis, and locate all the cold and cracked solder joints, especially near the tuning modules. If this does not take care of the problem, the tuning modules will need to be removed for re-soldering on the actual tuner modules.

If none of the above works, then you can always use the audio/video outputs of a cable box or vcr to the a/v jacks of the tv, thus bypassing both tuners in the tv.

Zenith TV- greenish color

If you take off the back of the TV there are additional tuning buttons. One is for the focus. I have a model SY2551S and have the green tint problem. Have you resolved that?

Color problem

Please fine tune those B/W channels to obtain color picture. If TV is more then 4 - 5 years old, it needs resoldering in tuning area or might need replacement of IF block.
