A lot of possibility can be wrong with your fault LCD monitor. The faulty LCD monitor may suffer power loss, the display monitor may shutdown intermitent, there may be lcd dead pixels, the ccfl/ backlight may break down or the screen display may not turn on. There are many issues that can come about that can cause you a headache.

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

The response is that you can choose either one. If you are careful, you can attempt to fix the problem on yourself. If you are unsuccessful, you can then pick out an LCD monitors technician to fix it.

Troubleshooting LCD monitor

The first method in repairing an LCD monitor problem yourself is to dissemble the lcd monitor cover. You can then check for

any loose connecters, bulge/ melted components, or a burnt board. You can measure a voltage by using a fluke multimeter. You can save backlights testing for last because the backlights are rarely defective.

One of the most general problems you 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 you can look. If you find that there is an issue coming from the voltage of the filter capacitor, then all you have to do is to replace the filtered condenser.

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

You can also check at the small electrolytic capacitors on the power / inverter boards inside the lcd monitor. If they are

bulged out, then there is a electrolytic leakage problem. You may even see a small amount of burnt mark on the component/

board, which it is usually an indicator of several component failure. You 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. You can solve the display problems when replacing the leakage or dry out

electrolytic capacitors.

Engaging a lcd monitor expert

If you would choose to have someone to repair the lcd monitor, you 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 you can decide whether or not you should buy a new lcd monitor instead. Now, new lcd monitors are inexpensive or just slightly than expert's repair services. If you pay more for your lcd monitor, then you may consider the second option.

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