How to test lcd monitor in easy way

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) May 14, 2010 -- A lot of possibility can be wrong with a fault LCD monitor. The faulty LCD monitor may suffer power loss, the display monitor may shutdown intermitent, there may be lcd dead pixels, ccfl inverter circuit or lcd ccfl inverter may break down or the screen display may not turn on or abnormal ccfl inverter voltage. There are many issues that can come about that can cause a headache.

But what do lcd monitor repairers make when they want to trouble-shoot LCD monitor? Do the lcd monitor repairers trouble-shoot yourself or do they choose a lcd monitor technician to solve on the problem for lcd monitor repairers?

The response is that lcd monitor repaires can choose either one. If new repairers are careful, they can attempt to fix the problem on themselves. If they are unsuccessful, they can then pick out an LCD monitors technician to fix it.

Troubleshooting LCD monitor

The first method in repairing an LCD monitor problem is to dissemble the lcd monitor cover. Lcd monitor repairers can then check for any loose connecters, bulge/ melted components, or a burnt board. They can measure a ccfl inverter 12v voltage by using a fluke multimeter. They can save backlights testing for last because the backlights are rarely defective.

One of the most general problems they can look for is an fault with the filtered condenser. If there is the capacitor issue with the open circuit or short circuit, this is one of the first components they can look. If they find that there is an issue coming from the voltage of the filter capacitor, then all they have to do is to replace the filtered condenser.

As long lcd monitor repairers distinguish the problem, they can apply the multimeter to test the starting circuit and the end of the circuit to ensure the voltage is not cut off. If the current is interrupted, then they know that there are component faults along that current flow making the problem.

They can also check at the small electrolytic capacitors on the power supply board and ccfl inverter board inside the lcd monitor. If capacitors are bulged out, then there is a electrolytic leakage problem. They may even see a small amount of burnt mark on the component/ board, which it is usually an indicator of several component failure. They can just exchange the affected components rather than purchasing a new lcd monitor. The parts can normally be found at a electronic component store that sells electronic components such as farnell, rs component etc. They can solve the display problems when replacing the leakage or dry out electrolytic capacitors.

Engaging a lcd monitor expert

If lcd monitor repairers would choose to have someone to repair the lcd monitor, they can have an LCD monitor expert. Most solutions are simple like dry joints, while others may be more extensive trouble-shooting and component replacement. It is better to ask for an quotation on the repair job so that they can decide whether or not they should buy a new lcd monitor instead. Now, new lcd monitors are inexpensive or just slightly than expert's repair services. If they pay more for your lcd monitor, then they may consider the second option.

Therefore, don't let the power circuit or the inverter board of lcd monitors to frighten new lcd monitor repairers away. It is manageable and rather easy to repair the LCD monitor themselves. Nonetheless, there is always the option of employing a technician if new lcd monitor repairers think that is the best option for them.
