Question about LG Studioworks 440SI 14" CRT Monitor
What all compoments should be checked
What power supply do you mean Sir/Ma'am.
is it the AVR (automatic voltar regulator)?
if its the AVR, just switch it on and check the output voltage with a multimeter (AC range 250)
you should see the voltage output nearly equal to your SERVICE AC voltage

This is an indication of out-of-regulation in the power supply section. The very
common caused of this fault is the leaky
electrolytic capacitor in
that section. It will drop the supply from normal voltage and
will disable the unit.It needs a little warm-up to make itself stable but the symptom will get worst. Sometimes it has a bulged/dome at the top but not all, it is better
that you have a capacitor
checker/tester to determine
its condition. Your unit will back to normal again if the leaky capacitor is isolated.
If you don't have necessary tools
and test instruments, and can't do the job yourself, I would advice you to
look for a professional to troubleshoot the problem. Don't
attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored
electricity enough to hurt you with a little mistake only.
Also check if your unit is under warranty /extended warranty,
avail it because the manufacturer of your unit will fix it for free. Don't open
the back panel, this will void the warranty.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
