Figure does not appear
If the picture does not appear, there is no problem raised by the image signal to the monitor.
The solution is check the video signal contained in the CRT board video adapter, because these components probably damaged or burned.

Cable to the CRT heater Open.
Every time CRT turned on, heater will work. When the CRT is turned off, heater yah so cold. Heat changes repeatedly and in a long time will make a heater to be open and heat seeping out of these cables.
The solution for this heater cable consists of three types (red, green, blue) we can see the damage on the color will appear. However, this cable can not be changed unless you change the tubes katodanya same selaki. When the cable is damaged, you practically have to replace your monitor with a new one.
Cathode connected to the control grid.
Cathode is a material made of corrosion-resistant metal, making it possible to connect to the control grid. If this happens, the control grid will lose efektivitaasnya, and will appear berakibatkan colors faded into Soak alias. In general, these symptoms often occur.
The solution when it comes in contact, nothing could be done. It's best to prevent contact between the cathode and control grid, by providing a barrier between the control grid with the cathode.

One or more colors appear weak.
If one or more colors appear weak, then this problem usually occurs because the cathode layer is formed which inhibits the release of ionic elektronmenuju screen. These symptoms make the cathode becomes less effective in firing electrons, which resulted in poor color on the monitor screen. These symptoms will be seen where one of the resulting color on the screen looks much weaker.
The solution drives check your CRT video board, whether the solder bond at one sagging or loose tube. Solder bonds. When the image was too blurry, the only possibility is to replace the tube. However, this kind of damage usually occurs only after prolonged use.

Phosphorus on the cathode tube was dull.
Phosphorus is a chemical compound that will bring a certain color when exposed to high-energy electron beam. In the old monitors, we often come across images that looked haggard, with contrasting colors that can be set up.
The solution there is no other way except replacing cathode tubes, but the age of phosphorus can be saved by adjusting the brightness to a minimum and you can install the screen saver on the monitor screen to reduce the phosphorus cycle is too long.

CRT Control grid at the Open.
Control grid is used to limit the light generated by the cathode, by placing a potential charge on the grid. When the control grid is open, as a result there is no longer a potential charge on the grid to control the light intensity and light will radiate with the intensity of management
The solution, check whether the cathode with the control gird with the cathode heater short circuit occurs (short) or not. If you do not find the short circuit (checked by using a multimeter) control grid may have been opened. The solution is the only tube should be replaced.

Focus on CRT grid open.
Oxidation can make a short circuit between the cathode with a control grid or control grid with a grid screen. Screen grid serves to mengarajhakan electron movement toward the screen. When the screen grid mengalamu short circuit, the electron energy radiating into the screen is reduced so that will reduce the intensity of fluorescent light on the phosphor and thereby reducing the overall brightness of the image. In some severe cases, precisely the image does not appear at all.
The solution, you can measure whether the short circuit occurs on the screen grid or not, by using the multimeter to measure voltage on the grid. Grid usually has a voltage between 250 to 750 volts in a normal situation. When the voltage is too low, then release matika drive monitor existing video board at the neck tube and then restart the monitor and measure the voltage again. When voltage returns to normal screen grid can be sure that the screen grid short-circuiting. If the voltage remains low, we may suspect there is damage to the circuit voltage yanhg set on a screen.

Picture looks red or turquoise.
If the picture looks red or blue-green (cyan approach), the problem is that there are problems in the video circuitry for the red line.
The solution, make sure beforehand that controls the monitor settings are at normal conditions. If the color control is set at a good condition as well as redness and not hilangh, check out the video drive circuit connected with the color merh. We memerluan osiloscope to track the video signal input and video output. If there tidk red video signal at the input amplifier, check the connection between the monitor with the video adapter board. When good connection, try using another monitor that works well. If the problem still occurs on the monitor, replace the video adapter board to monitor the damage. We can compare the signal characteristics of the broken monitor with a good monitor and draw conclusions, which is the problem. If you do not have such equipment oscilloscope and did not really want ribet, simply replace the entire board video adapter.

Images looked old in blue or appears yellowish color.
When the images look old in blue or appears yellowish color, the problem is the drive circuit video broken blue line.
The solution is the same as the previous problem, you can walk the same way to check the source of the damage. Previously, we have to ensure that the colors on the monitor settings are at normal position.

Images looked old bluish-green or red.
If the pictures look old bluish-green or red (nearly magenta), the problem is the drive circuit broken green lines.
The solution is the same as the previous problem, you can walk the same way to check the source of the damage. For the last three masaah, when the video signal is measured to work well, but it still appears the same problem, suspect damage to the CRT itself. Possibility, cathode or damaged gridnya control. If you have the means to test CRT, check the tube is still good or have been Soak. When a bad result, like it or not you have to replace the tube.

Horizontal or vertical lines appear in the middle of the screen.
If the horizontal or vertical lines appear in the middle of the screen, the problem is damage to the drive circuit horizontal or vertical.
For practical solutions, you change the main monitor board. If you are a little bothered, you need to check the circuit that produces a vertical sweep of the board. Check that all cables are connected properly. Sometimes, the damage is caused by the cables loose from excessive heat in the system monitor.

Images Only Appear in the Upper or Lower Monitor.
When the images only appear at the top or bottom of the monitor, most likely the problem is the vertical amplifier
The solution, use the oscilloscope to check this amplifier. If there is no such tool, replace the main board monitor, then when the image was saved again, be sure to check the monitor vertical linearity.

There is no picture or raster.
If there is no picture or raster, the problem is the monitor cable connection to the CPU and video card is not working properly, or damaged circuits in the monitor.
The solution is first make sure that the CPU and video card is working well. After that, check out the damaged monitor and try to turn the brightness and contrastnya. Start by checking the vertical synchronization signals and horizontal. If there is no signal, it will not appear raster. If the signal is likely that the problem is the high voltage regulator circuit or the horizontal drive does not work with it properly. If one of the output of power supply problems, we can resolve it by checking the power supply circuit or replace with a new power supply.

Characters that appear on the screen is not perfect.
If the characters that appear on the screen is not perfect, the problem disturbed by the presence of monitor other devices that emit a specific wave. Another device that for example radio, television, phone, or other monitors that emit electromagnetic waves or magnetic fields cause.
The solution is keep the equipment cause interference. If interference still appears likely masalahnyab on our own monitors. Possible location of the problem is in the drive controller vertically or horizontally or both. When the sweeping raster speed changing screen, the pixels in an image that appears on the screen may be close together, while the pixel area of the other screen will appear too long. Try checking lineariatas vertical and horizontal drive.

Display that appears looks bumpy.
If the view that emerged was bumpy, the most likely source is the power supply.
The solution, use a multimeter to check the output of each power supply to all components. If you've found the problem of electricity supply, improve electricity supply line to the place or for practical, just replace the power supply board it as a whole.

Appears to change color when heat monitors.
If the color appears to change when the monitor heat, most likely there is damage to the video amplifier circuit.
Should, monitor to bring the same color in both cold and hot conditions. Turn off the monitor and open the lid, then start check the video cable, particularly cable connecting the board with the inside of raster monitor. If the connection is too loose, tighten it. Also check the connection between the video amplifier board with raster board.

Figure narrowing the horizontal direction when the heat monitors.
When the images narrowing the horizontal direction when the monitor heat, the problem is one of the horizontal sweep control circuit is weak or change its value when the monitor heat.
The solution is turn off the monitor, check all capacitors laluy who beralokasi around the horizontal output transistor. Often, such problems are very difficult to detect, because it detects a damaged capacitor is very difficult. So start by checking the solder connections between the circuits and wires. If the problem is not resolved, needs to be done is to re-soldering of all components on board transistors and raster.

Figure wide horizontal direction when the heat monitors.
If the image is extended to a horizontal direction when the monitor heat, the problem with narrow horizontal image.
The solution is the same as narrowing the image problem. If you do not want to check one by one component of the problem, you can simply replace the board with the new Raster.

Figure detail in the high-resolution graphics blur.
If the image detail at high-resolution graphics blur, most likely the video amplifier circuit Soak or too weak. High-resolution images require high bandwidth, so its video amplifier that requires rapid response variations between pixels. If the video amplifier is weak, high-resolution images on going a little blurred. This problem will disappear when the monitor to work at low resolution.
Check the video amplifier solution that produces an electron beam. If there is damage, replace or repair such parts only. Temporary solution, do not set the monitor at a resolution too high.

Images that appear broken and unstable.
If the images appear broken and unstable, the voltage regulator circuit board raster or problematic.
The solution circuit and check all connections on the board. Remember that the main source of producing the three primary colors that give a picture presentation when not working perfectly as problematic. Re solder all the connections on the video amplifier board if necessary.
