crt tv solutions damaged

Perhaps we often hear people say "oh TV broken jug." The question that arises then, is it true they were damaged tube TV. The answer may be yes can not.
Sometimes we look at our screen is not intact (depressed / or folding) so that there is a black section at the top or bottom, sometimes if the damage is severe there is only a horizontal line across our TV screens. People who do not know anyone diagnose the tv is broken jug. This is wrong. Our TV was not damaged but the jar is broken on the vertical synchronization.
Then there are also depressed the side of the screen left or right. It's also not because of damage to the tube. For this damage there is some possibility that corrupt: could the horizontal section, Fly back transformers, power supply, or perhaps only the electrical voltage in your house are too ngedrop.
Then the trapezoidal-shaped screen or a depressed left, right, top and bottom. Typically for this damage often occurs due to the deflection coil short / shorting because of peeling layers of this email. Damage if left unchecked will spread to the horizontal section and other parts or even worse will make us die tv total.
Subsequent damage is the dominant color tv looks a particular color or no color that is unusual or loss of a particular color. For this damage could be a tube television is truly broken. but it's good we simply diagnose own destruction if we understand a little electronics knowledge.
To damage this color, things to do is look at what the dominant color or colors are missing. (Red, green, blue) because it is technically a color tv is a merger of the three elements of color.
Once we know what color is missing, we can take that next step is to try to improve or to call a service person if we are not able to fix it.
The question may be how to find the damage or repair this damage?
Here I will try to write a little trouble shooting on this type of damage is simple:
after we open the casing, the rear of the tube there is a small PCB and attached to the rear tube. It is from the amplifier PCB color. usually damage often occur there. The first step you can do is clean the surface of the PCB with tiner, and then do the strengthening soldiran there by way of re-soldering the legs of the components that exist there. soldiran cracks that are not seen clearly by eye color can result in damage earlier. and sometimes with steps that can overcome the damage. Nb: for TV brands National / Panasonic usually with this step can not recover damages even though the initial damage is the release soldiran. steps to take is replace the transistor amplifier in the PCB color (red, green, blue) all three at once.
If after the re soldir but color is still not normal, is now our turn to check it true that our TV tubes are damaged or indeed any other damage. The way is simple.
Take our multi-meter cable, can be a black or a red. Then plug one end on the ground of our TV (chassis), then turn on the TV, then one end of the cable before we plug it into a cathode tube feet on the small PCB earlier. There are 3 cathode there, red, green, and blue. Usually written in the PCB cathode KR to red (red), KB to the blue cathode (blue) and KG for cathode green (green). Notice the screen changes when we do this step. The color screen will be the dominant red color when we'd plug in a red cathode, as well as for other colors.
If the colors on the screen does not change when we plug the cable into the cathode, are suspect damage to the tube (screen) from our tv. Although it could happen CRT socket of the pin loose.
When the diagnosis we express our TV tube is not damaged, we can make small repairs to replace a active / passive in the little PCB. Typically a transistor that is often damaged. If we can not or are afraid to do so, we can call a service person. with a light lunch we had our diagnosis can be denied if the technician / handyman service we declare tube / tv screen is broken.
