My monitor model is dead no led blinking power cord ok
You need nto open it up and inspect it, here is the service manual; http://online.manualspace.com/computer-monitors-free-ebooks/lg-monitor-service-manual/4721/lg-studioworks-500e-500g-500n-color-monitor-service-manual-314.html
Hello, welcome to Fixya!
Your monitor is having a power fault
because it is not switching on. The monitor might have worked fine in
the past, but that's electronics for you. Power surge, irregular power
supply, excess power supply, etc can affect the unit thereby not making
it to power on.
First, remove the unit's power cord from the
wall, wait for about 30mins, then plug it back in. If it doesn't power
on, plug it into another outlet, to make sure there electric current
entering into the rmonitor.
If plugging into another power outlet doesn't power it on then it confirms that the receiver is having a power fault.
When
electric current comes from the power outlet into the monitor, it goes
straight into the power supply board which then circulates the current
into the unit. So if the monitor doesn't power on, the first thing is to
make sure there is power entering into the monitor.
So check the
power cord, if it is a 3-pin plug, it must have a fuse in it. check the
fuse if it is not blown. if fuse is intact, then power supply board
should be checked.
This unit must have a power supply board in it
where power enters from the mains. A capacitor, fuse, diode, etc may
have been defective on the power board and maybe that's why its not
making the unit turn on. There might also be some disconnection or
something, inside the unit which is not making it to power on.
To
actually find out what's wrong, you need to disassemble the unit with a
screw driver and check what's wrong. You will be needing a meter and
continuity tester in order to read the components on the power board.
Once you detect any bad component, you can make necessary replacement at
any electronics accessories store withing our vicinity. This is the
only way by which you can detect and solve the problem.
Of
course, testing the power board with a meter will require someone that
has the ability. So it you can't, then you might be needing the help of a
repairman or you can call a friend that has the ability to help you
out.
I wish you the best of luck.
Regards.
