Before taking action to dismantle the monitor make sure the damage is coming from the monitor, rather than The computer, in general, because many people assume komputernyala but not showing the picture was immediately say if the monitor is problematic, if you have a problem trying to restart the computer and press the NumLock on the keyboard if lampunua life tap once again if the light off means the computer to normal life, please disassemble the monitor.

No Picture Nor Raster.
If there is no picture or raster, the problem is the monitor cable connection to the CPU and video card is not functioning properly, or damaged circuits in the monitor.
The solution is make sure first that the CPU and video card works fine. Horizontal transistor check, try turning the brightness and contrastnya. Start by checking the vertical and horizontal synchronization signals. If there is no signal, it will not appear raster. When the signal is there, most likely the problem lies in the high voltage regulator circuit or the drive does not work with horizontal handle it well. If one output of power supply problems, we can overcome them by checking the power supply circuit



Image Not Appear
If the image does not appear it indicates no signal detected on the image to be raised to the monitor. The solution is check the video signal contained in the CRT board video adapter, since this component might be damaged or burned.


Cable Heater On CRT Open.

Each time the CRT is turned on, the heater will work. When the CRT is turned off, the heater also picked up on so cold. Heat changes repeatedly and in a long time will make the heater to be open and the heat seeping out of these cables.
The solution for the heater cable is composed of three kinds (red, green, blue) we can see the damage on the color that will appear. However, this cable can not be replaced unless you replace the equal selaki cathode tubes. When the cable is damaged, you practically have to replace your monitor with a new one.


Cathode Connected With Grid Control.

The cathode is a material made of corrosion-resistant metal, making it possible to connect to the control grid. If this occurs, the control grid will lose efektivitaasnya, and will berakibatkan colors appear to be worn out faded alias. In general, these symptoms often appear.
The solution when it happens, nothing is impossible. It's best to prevent contact between the cathode and control grid, by providing a barrier between the control grid with all katoda.Satu or More Colors Looks Weak.
