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.
