Myhistorytodays,Article How to Fix Damaged Monitor - Monitor is an important device in a computer device, because without our monitors will not be able to see the output or the work computer to be on the show. Just as a man without eyes or blind, the same as the monitor into an eye in the computer. this time I will discuss about how to fix a broken monitor. Here I will explain how to fix the monitor, so even though the school this explanation does not exist but I try searching on the internet, I finally get a powerful way to improve a monitor, a monitor is quite important in a computer because if there is no monitor to view a computer program we can not, at least if you have a projector to view the computer, just ok you can read the following methods on how to fix a monitorhow to fix a broken monitor
1.lid back of the monitor so that all components at visible and accessible workshop equipment such as multimeters, toolset, as well as other tools. Be careful to monitor the condition that this open, especially when the electricity came on the circuit, because there are extra high voltage of 16,000 volts to 30,000 volts that are harmful to the human body.
2.multimeter to measure the incoming AC voltage on the power supply circuit monitor, is normally measured 220 volts great. Continue to measure DC voltage which released the power supply to the circuit monitor seluruhnya.Tegangan DC on each monitor different brands and types of different magnitude in accordance with the design of each plant. Use the scheme in accordance with the type of monitor that is being improved, the scheme can be obtained on the packaging of the complete user guide when buying a monitor.
3.voltage power connector on the horizontal output transistor, generally by 90 Volt DC on kondisim normal. This voltage shows a high voltage generator working conditions which can turn the picture tube. If this voltage drops by half, can be sure there is damage on a series of horizontal, replace it with a new power transistor. To replace the new power transistor should use exactly the same type, but if not possible then it can be replaced with other transistors of the same nature and a higher voltage rating.
4.hanger light intensity (brigthness) on the front panel of the monitor until the maximum position. See reaction on the picture tube, if there is no change in check the circuit around the transformer tegangangan extra high (flay back) on your premises. extra high voltage to ignite the picture tube.
5. may occur on a charge of high voltage diodes rectify horizontal signals into DC voltage of 16,000 volts - 30,000 Volt. To test the use of high voltage diodes high voltage probe for multimeter special-purpose high-voltage testing. Compare Ac incoming voltage difference with DC voltage transformer issued diode, the DC voltage measured on the diode cathode to 16,000 Volt - 30,000 Volt. Be careful using this high voltage probe, a touch to the conductor of which one will cause sparks.
6.Can also check the capacitor that connects the high voltage transformer to the ground. Remove these capacitors and measure with a multimeter, if there is a leak replace it with a new capacitor. Capacitors are already dry will change the value of its capacity and the resulting changes in impedance in impedance rangkaian.Perubahan this will affect the extra high voltage transformer can not generate a voltage as needed, it will be visible on the screen were dingy, poorly lit or brightness regulator does not work.
7.Beside above disorders, monitor does not display an image caused by damage to the power transistors in the power supply, FUSE broken, horizontal output transistor, capacitor kompling output, high voltage diodes, deflection rolls dropped out (burned), RGB matrix input loss and so on. Use a monitor that shows a complete scheme of each section and check in sequence starting from the power supply up to the picture tube.
8. After all the components that were damaged in the new locker, turn on the computer to try to monitor the newly fixed by the diagnosis program. Diagnosis programs that run specifically on test menu displays can be made in the guidelines for repairing computer monitors, such as check-It, QAPlus, PC-Technician, JC-Bench etc.
Now that I am talking about are How to Overcome Life PC, Monitor Off and No Beep Beep.
In accordance with the experience I often experience life PC, monitor off, no beep and does not appear the BIOS boot, I'll tell briefly how to cope.
Immediately see how that is below
The first way:
- You try to unplug the monitor mounted on the VGA port on the back of the PC Casing (do not forget to turn off your PC in advance)
- Afterwards reattach the monitor cable to the VGA port, restart your PC
- See what there is a change on the screen, if the monitor is in conjunction with the PC it means to be successful, it means the problem is in ill-fitting cable attached to a VGA port
- Sometimes the problem is in the onboard VGA card and must be replaced with additional VGA card.
The second way:
- Unloading your PC (turn off the PC first)
- Unplug the memory RAM
- Clean the pins or plates such as copper yellow color with eraser slowly, if it replace the RAM memory in the same place (do not connect the first casing)
- Turn on your PC, if the PC and the monitor simultaneously means succeed, it means the problem is in the dirty RAM memory
- Sometimes the problem is in RAM memory is defective and must be replaced with new RAM memory.
The third way:
- If you are still living together (PC was still not closed its casing), trying to move its RAM memory to another slot (PC is turned off)
- Turn back, if the PC and the monitor simultaneously means to succeed, it means the problem is in RAM memory slot.
Caution!
- Do it repeatedly over how to succeed
- Try rest of your PC, if you have been using, your PC probably tired
