Sony Tv Shows In Black And White

Strong magnetic fields from other devices

If you have a CRT TV, the fading or complete disappearance of colors can be caused by prolonged exposure to a strong magnetic field. Plasma and LCD models are not subject to this defect. Also, such behavior can be caused by improper operation or complete breakdown of demagnetization, but the devices on the tube of the kinescope.

Why color TV began to show in black and white?

Modern TVs differ from the models of the past in image quality and color reproduction. Companies such as LG, Samsung, Sony, Philips and others are constantly developing new display formats and require owners of their equipment for a variety of colors and their realism. Therefore, when a malfunction appears associated with the transition to black and white, then the person perceives it especially acutely, feeling a kind of degradation of technology.

Repairs

Elimination of this type of malfunction is performed as follows:

  • First, the search for the required setting is carried out in manual mode, which is accompanied by trial attempts to adjust;
  • You can also turn off the TV for a short time, in the hope that after a complete de-energization, all control and monitoring elements will return to their original state;
  • Using a special function in the TV menu, reset the settings to the factory settings.

Repairs

There are three ways to fix such a defect:

  • Update from the official website of the manufacturer by connecting the TV to the Internet;
  • Download the firmware to a USB flash drive and install from it;
  • Call a wizard who will sew the TV using special equipment and programs.

Repairs

It is not worth making an independent repair and replacement of this element. It is better to ask a service center for help, having previously named the model of your TV. So the master has the opportunity to immediately sculpt the part necessary for replacement, which will save time.

Possible causes of malfunction and their elimination

When color disappears from the TV, there may be several reasons for this behavior. Some of them can be eliminated by the user on his own, by performing the simplest manipulations and changing the settings. However, there are also such breakdowns among them, the correction of which requires the participation of a specialist and the use of a special tool.

Color board malfunctions

complex breakdowns, when the TV shows in black and white, include a malfunction of the color reproduction board. In this case, the image may be completely absent, or may be played back only in BW mode.

Only a master can repair this breakdown. Because in this case, a replacement part is required.

Failed settings

If the color rendition is disabled on only one channel, it can be restored using the remote control. Go to the menu and set the chromaticity in the desired range. If this did not bring results, then most likely this is not the case.

All channels are usually tuned to the SECAM playback system, all government channels operate on it. But if you have cable TV connected, then some channels may be set to PAL system. You need to look in the settings and switch the system to a color image.

Self-diagnosis and repair

If the TV has become black and white, you need to check the color rendition in the menu using the PU. This approach is logical if all channels show the same. When only one of them lacks color, it’s not your technique. It is necessary to call the operator of the company providing the TV so that they can debug the normal operation of the broadcast.

You should also check the antenna. Its signal is damaged in many cases:

  • Torn or partially exposed cable;
  • The plug came off;
  • Outdoor antenna broke.

When the settings go astray on a regular basis, qualified intervention is required. You cannot troubleshoot your Sony or Philips yourself without the proper skills. Also, do-it-yourself TV repair is hazardous to health, since some nodes accumulate charge and give it out when touched.

Electromagnetic interference from other devices

Also, black and white channels on the TV can appear when it is exposed to a strong electromagnetic field from another device. Often, owners of CRT television receivers encounter such manifestations. LCD and plasma models are not subject to such influences.

If the TV has lost its color due to demagnetization, firstly, you need to remove all devices that generate an electromagnetic field away. Then, you need to completely disconnect the TV for a while and reconnect it. If that doesn’t work, you can find the demagnetize button on the device’s case and press it. If after this the color rendition has not returned, then you need to contact the master, who, using special equipment, will demagnetize.

Why did some channels go black and white?

Some black and white channels on the TV indicate outdated software. The human factor does not actually play any role here, except that you can forget about updating the firmware. Modern equipment itself finds the source of the problem and invites the user to upgrade. All you need to do is click “OK” and wait a while.

outdated equipment is not updated on its own. You will need to look for the necessary software on the Internet yourself, download it to a flash drive and update it manually.

Why did TV go black and white

  • Problems with incorrect settings.
  • Poor signal.
  • Interference from other devices.
  • Color board malfunctions.
  • Defects in firmware.

Some of the reasons that caused the lack of color rendition can be eliminated on your own. For example, restore lost settings. But to fix other problems, you will need to invite an experienced specialist who has not only the necessary knowledge, but also has a special tool.

Let’s analyze each and the reasons separately.

Poor TV signal

If the TV turns black and white, an antenna malfunction may be the cause. Perhaps its plug is not fully inserted, or the antenna itself is faulty. Make sure the plug is connected correctly.

  1. If the antenna is indoor, then twist it or rearrange it from place to place to find the best signal reception point.
  2. If the antenna is outdoor, then you need to inspect it. It may have been damaged or dislodged by a strong gust of wind.

It is possible that a poor-quality signal is transmitted by a faulty tuner, set-top box or other transmitting device. In this case, you need to inspect and repair this device.

The new TV began to show black and white images

When a new TV shows black and white, first of all, it is recommended to contact the warranty service center (if the device was purchased from authorized distributors). In accordance with the sales contract, they are obliged to solve the problem, replace the broken ones with original parts taken from their own warehouse, or completely change the equipment.

The screen of the new TV does not display correctly if the connection is incorrect. The colors of the plugs correspond to their purpose:

  1. Red, white. Mono and stereo audio (all audio tracks).
  2. Yellow. Composite analog signal (picture feed without sound). In standard mode, it receives and transmits PAL, SECAM and NTSC signals. Colors are transmitted together, fork release completely removes color.
  3. Green, blue. Component signals. They are transmitted without sound (connected separately), and served separately (unlike the previous version). The outlet plug is characterized by partial and single loss.

Factory defects are also causing black and white shots.

Why did TV go black and white

  • Problems with incorrect settings.
  • Poor signal.
  • Interference from other devices.
  • Color board malfunctions.
  • Defects in firmware.

Some of the reasons that caused the lack of color rendition can be eliminated on your own. For example, restore lost settings. But to fix other problems, you will need to invite an experienced specialist who has not only the necessary knowledge, but also has a special tool.

Let’s analyze each and the reasons separately.

Why does the color disappear

The loss of a color picture is not always associated with a breakdown, sometimes the cause is a human factor. The most common sources of this problem are:

  • Antenna damage. Black and white channels on the TV indicate poor antenna signal. You need to contact your TV provider to amplify the signal. If this does not fix the problem, then the device itself does not perceive the broadcast well. A professional master will help here.
  • Settings failed. There are several color schemes in modern television systems. PAL, NTSC, SECAM. If you adjusted the metrics for different channels, the color values ​​might get lost. The user manual usually tells you what to do to get the settings back. If you are not sure if you can handle this, it is better to call a specialist.
  • Interference from nearby appliances. CRT users may notice that the image becomes dull at first, and then completely loses color. This indicates that the device has been exposed to strong electromagnetic radiation from other household appliances such as a microwave oven, coffee machine or vacuum cleaner. In this case, the kinescope will demagnetize and lose its properties. It is for such a case that there is a special restore button on its case. You must move the TV away from other devices, turn it off for 24 hours by pressing the demagnetizing button. If this does not help, then contact a specialist.
  • Connection errors. If you transmit a signal to the screen using RCA wires. Tulip, you need to connect them carefully. The yellow plug is responsible for the picture, if you use a red or white image on the monitor does not appear or it will be b / w.
  • Old firmware. LG and Samsung LCD models do not work without dedicated software. With each firmware release, something is seriously changing. If you canceled the automatic update, over time, the software will not process the TV signal correctly. Therefore, if the TV shows in black and white, you need to update the firmware. You can download it from the manufacturer’s official website or contact the wizard if you have problems during installation.

Color TV went black and white, why?

If your Plasma or LCD TV turns black and white, check the settings first. Loss of color does not always indicate serious damage. If you do not know how to properly restore the device to work, call a specialist.

Breakages that affect color

If you removed all the interference, installed the current firmware, restored the settings, but it still did not help, perhaps the device had a failure and one of the parts broke. Most often fail:

  • Antenna plug. The damage is often unnoticeable. In 25% of cases, it is impossible to visually diagnose a breakdown. But if you at least once abruptly pulled the cable out of the socket or stepped on it, the signal will arrive with defects.
  • Color reproduction board. Usually this part is well protected by the structure, but if the room has high humidity or the wiring in the apartment is damaged, there is a risk of voltage surges and even a short circuit. At the moment of a power surge, the color card will burn out first. It cannot be restored in Sony and Philips models; replacement is required.
  • Switch. If you use this unit to receive a good TV signal from different sources (for example, satellite and cable TV), the failure will happen in it. To check if it works, connect each signal source to the TV device directly. If colors are restored, simply replace the switch.
  • Matrix controller. If all other malfunctions are not confirmed, the screen microcontroller may have failed. Many workshops do not undertake repairs of such complexity and offer to replace the entire matrix assembly. Repairmen can install the original controller instead of the broken one. It will cost significantly less.

How to set up PAL and SECAM system

The most common cause of a color defect in a TV is a color system failure. The problem is that state channels are encoded using the SECAM system, a Soviet-French concept of analog color reproduction. But all digital and cable programs are tuned to the PAL line-by-line phase change circuit. Therefore, one or several channels can lose color on a modern device, and not all at once.

Therefore, if you suspect that the channel settings are out of order, proceed as follows:

  • Enter the menu.
  • Find the item “Picture Format” or TV Format.
  • Select PAL from the drop-down menu.
  • The color must return.

If that doesn’t work, there might be a configuration conflict. Use the “Return to factory settings” button or contact the service.
