I have a jvc iart television and i had to transport to my apartment now i have green and red colors in each corners.. How do i remove those colors??


hello,
the problem is a colour patches , you can solve this by using a big size magnet like that in an audio speaker to remove the colour patches.
you do this when the television is power on, and gently moving the magnet towards the screen of television.
hope this will help...

My flatscreen tv is distorted


Speakers can cause problems with the correct display of video on TVs but usuall it only concerns direct view tv. Projectors should not have any problems or flat screens. I think you have a different problem Explain better what you mean by distortion in the JVC. Let me know and I will try to help you.

Our tv is magnitized by our surround sound base speaker what can we do.


Hello. Here are the steps:
1.put your hands in the form like you would if you are about rub your hands together for warmth
2.Put the magnet between both hands at the palm areas
3.rub your hands together and turn the magnet so that the north and south ends magnetize the TV simultaneously
4.make sure you know where the north and south ends are located on the magnet
5.Hint - The Constant switching between the north and south polarizations causes the magnet to equalize the magnetized areas on the TV returning it to it's original color!
Regards, Joe

PS kindly rate my answer. thank you.

Picture is now black and white


 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:

  1. Weak signal or defect in tuner/IF causing loss of signal strength.
  2. Coler killer set too high (internal control) if it has one.
  3. Defective part around the chroma chip/circuit. Faulty color oscillator.
  4. Bad connections in area of chroma chip/circuit.
  5. Defective chroma chip (don't suspect this first just because it is probably very expensive).
A service manual or Sams', DMM, and scope will help greatly in attempting to troubleshoot this unless it is an obvious bad connection. 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.

TV KOLIN 21"


hello.... do you have any speakers near your television? what color is the circle your talking about? Do the green,pink colors are scattered all over the screen and specially on the corners?
If you have or had speakers near your tv? then do this try to get a magnet.a magnet on a speaker would do.what you have to do is to place the magnet near the screen of the tv approx. above the green,pink color (turn it on first).you will notice the that the color will react with the magnet try to pull it on the side you will notice that the green,pink color is moving on the same direction do it until its gone.NOTE make sure youll not scratch the screen ok.email me what happened. jaredreyesbalderama@yahoo.com GOODLUCK

Color is not good around outer edges of picture


When the colors are off around the edges on a regular picture tube TV, it usually means that the degaussing thermistor's solder joints have cracked loose. Another possible cause is that a strong magnet, such as in a stereo speaker, was brought very close to the picture tube and has magnetized the tube. Resoldering the solder joints on the degaussing thermistor and demagnetizing the picture tube should put the color back to normal.
