TV is now colorful，It looks more vivid but，If the color displayed on the TV is not normal， I will feel very annoying。I don't look good, so I want to adjust the color.，Second， If the color of the new TV is not satisfactory，Simple adjustment，then，What should I do if TV color abnormality?？How to adjust？
What if the TV color is wrong?？
Everyone knows that the color of the color TV is very beautiful but，What if the color of the TV is incorrect?？That will affect watching mood，Nowadays， I will discuss the adjustment steps and methods of color TV：
1。 Adjusting the contrast of image contrast will reduce image level，Seem straightforward，Many image details are lost，In addition， Voice interference images can also occur。Contrast adjustment is too low，It also reduces image level，It seems that it is very laborious，You need to use the contrast knob correctly，Six grayscale levels that can be clearly clear，Make the leftmost level just close，The brightness of the last level is appropriate。When the color saturation button is closed，Due to different signal levels of colors，It should be able to clearly define your own level.；
2。 Adjust the brightness and background color to adjust the brightness knob of the color TV，Make brightness，Never let people look，Chaotic，Don't be too dark, watch TV, it is best not to get tired.。Then close the color saturation，No image，Rendering black and white。Color TV with tone knobs need to adjust the color phase knob to the smallest；
3。 Adjusting the clarity and contrast levels can represent some conditionsCRTStrength of the signal。Adjustment contrast indicates that the signal strength of the image tube is appropriate.，Now you can adjust horizontal resolution。Adjust the tuner knob or channel fine-tuning knob，Should carefully observe the level and clear pattern in the test map，Try to make a small vertical line clearly read，And there is no flap and tail。It also needs a good voice，Not interfere with the image。In the color TV test chart，The position of the thick line can be distinguished from the right side，Indicates that the horizontal resolution of the TV is high；
4。 When color saturation is adjusted，Adjust color saturation，First turn the color saturation knob to the minimum position，Then adjust the color depth according to the TV viewer's own preferences。If the color is too strong It will lack realism。Too much widespread color meaning。A more appropriate standard is：Image of characters in the image，Especially the color of the hand and face，In order to close the skin color of ordinary people，That is， Can adjust color saturation knob，Normal skin color skin color。In addition，Adjust the color time frequency fine tuning knob to properly adjust。
When the TV color is incorrect， You can refer to the method above for trial。of course， If you can't solve the problem， You should contact professional and regular maintenance departments for on-site inspection。
How to adjust TV color？
1。 TV is colorless to become black and white
（1）Audio and video cable connection error。Ordinary TVAVinterface， DVDinterface Component signal interface andSport。Make sure the output interface of the set top box is consistent with the input interface of the TV。
（2）TV system is incorrect。The standard of ordinary TV in my country isPALmode，Please check if the TV isAUTO / PALformat，IfNTSC / SECAMIncorrect in format，Need to change。
（3）magnetization。Need to be degauss。
2。 Color bias
Color difference is two cases。First, the overall color bias，One is a bias bias。If it is a bias，It may also be related to magnetization。
How to adjust the overall bias？
（1）Open the back cover，usually， There is a circuit board on the rear seat of the image tube.，Five potentiometers can be easily found on it。Usually should be driven by two colors，Three primary color adjustments are usually English symbols are not difficult to understand。
（2）Set TV brightness to relatively dark，Color is completely closed to black and white，Adjust the basic level of the two colors，Very simple，Red is red，Greener The less green, if there is more blue，Have the same。anyway， Just turn it into white。
（3）Then set the TV brightness to the brightest，Adjust two color drives，The adjustment method is the same but it may miss the color at this time.， You can increase or reduce two colors that can be adjusted simultaneously。After adjustment, return the color and brightness setting to normal，The color of the TV is pure。
（4）This method is very useful for the color of the old TV。Not too difficult to just pay attention to indicate high pressure on the high pressure cover of the tube，High pressure assembly on the high pressure assembly on the developing tube base has high pressure，Please note。
3。 How to deepen
The TV magnetization above is easy to lead to abnormal TV color.。So how do you deepen?？
（1）first of all，See if there are some strong magnetic equipment around the TV。The door seal of the refrigerator like a refrigerator has strong magnetic properties，Will 易彤破壁机不工作维修 make your TV screen magnetization。If the side does have a magnetic object， Turn off the main power，30After a minute，Please do not use the remote control to close the power。
（2）The surrounding environment is considered to be magnetic，Remove2Miyuan。
（3）Place a magnet on the screen to desene。
（4）Using a deminator，General electronic parts stores can be sold，Not very expensive。
（5）Unable to solve，The degaussing electrical resistance in the TV is broken.，Need to replace。
4。 Bias caused by TV aging
If there is no magnetization，It may be because your TV has been used for a long time.，Bias is normal。If there is a certain electronic maintenance foundation，TV can be opened。There is a circuit boardSMaintenance switch，Play it to repair shop，Open，You will see a horizontal bright line。Then adjust the tail light board3 Rs。G。B．Potentiometer Slowly adjust the potentiometer in turn。View the color of the horizontal bright line。Until the whitening。
