Re: kolin color tv,degausing problem.

Degaussing coils do not work on LCD or Plasma TVs, Cathode Ray Tubes only. There should be no (not any type) demagnetizing circuitry on that type of set, so I have no idea what you replaced/adjusted. I believe one of two things to be the problem. Either the LCD screen itself is bad (possibly it has been struck with something and that has broken electrical connections that cannot be repaired) so replacing the LCD panel may prove to the the fix. However, the circuitry that drives the LCD panel could be at fault, improperly driving an otherwise good LCD screen. That is a tough call. I would carefully inspect the screen up close looking for tiny cracks in the glass. This could be a pricey repair either way. Good luck on that one. Perhaps you should include some more history of the set. Did it fall or get knocked over, was recently moved, got wet... anything would be helpful. I know that children of a certain age are known to go up to a set and slap the screen. A friend has a rear projection Pioneer with that type of damage.

Red Tint on Screen

This is normal and is a color calibration issue.

For correct color, NEVER use the "WARM" setting. Why? Too red. You cannot get REALISTIC or ACCURATE color using the "Warm" setting.

Since we are speaking of Samsung, first avoid the "Flesh Tone" adjustment. When things are set correctly there is no need for this adjustment. It is a quick fix and not for the "discerning eye".

1. First, access the "Color Temperature" menu. From here select "Cool2" or the coolest temperature setting.

Note: For Samsung use "Cool2", or if not available, "Cool1". Samsung has inadvertently increased calibration confusion by issueing TVs that have just "Cool1", and TVs that have both "Cool1" and "Cool2" :0[

For other brands, use "Cool", or "High", or "+6500k". Anything lower artificially reddens the picture and compromises detail.

2. Now return to the color settings and reduce "Color" to between 30 and 40 (on a 100 scale). The sweet spot is just near the place where the color rapidly washes out.

3. To round out the color palette, move to the "Tint" adjustment and ADD a couple (3-5) clicks to the GREEN.

Adding the touch of green is what is needed to take out the last bit of "pink" and will make all the tones and all colors display properly.

I hope this helps!

My panosonic lcd tv has devepoped multiple bright colorspots

This is caused by magnetic fields. Either the speakers of tv is faulty or demagnatziser not working. Switch of tv and remove powercord from wallsockets. Leave for about 10 hours and plug in powercord and switch on. if demagnatiszr is working the blue will be gone. if not have youre tv demagnetized

If hometheatre or radio speakers are closer than ½ meter this could also generate coulouration of screen. move speakers further away. If tv is on and and being moved your static electricity can also cause this. So switch of if if you move your tv.

Magenta Color

Here is something that may help from the website under your model number television. Q. Why are people on my screen green?
Models: 32HL17, 37HL17, 42HL17, 42HL167, 47HL167, 52HL167, 42HL167, 42LX177, 46LX177, 52LX177, 57LX177
If the problem is not the connections, try adjusting the tint on your television. A high tint setting will usually create a green
image on the screen where as a low tint will create a more red hue. In order to access your television's tint:
1. Press the “MENU” button on your remote control and use the LEFT or RIGHT arrow keys and select the
VIDEO menu.
2. Then use the UP and DOWN arrow keys to highlight PICTURE SETTINGS and press the "ENTER" button on
your remote.
3. Next use the UP and DOWN arrow keys to highlight TINT then use the LEFT or RIGHT arrow keys to adjust the
TINT. If the picture is too green the tint will need to be lowered.
4. Once you have adjusted the tint to your liking, use the DOWN arrow key to highlight DONE and press ENTER. The toshiba customer service telephone number is : 1-800-631-3811. I hope this helps you with your problem.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.
