Question about Philips 230W5VS (Silver) 23" LCD Monitor
It's not powering on at all.. seems like dead... I tried to open it to check some basics but wasn't able to open. Any docs on how to open this monitor?
Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After that, you need to check if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

Here are some basic steps that will help you fixing the problem.
I'm assuming that your unit is dead set without an standby LED
light and your outlet is live.1.Power cord - check the cord it might be opened (no
continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse-
sometimes the fuse fail because of the power
surge, replacing with new one will cure the problem, If this is the case I
would advice you to use surge protector/AVR (Automatic Voltage Regulator).
However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the
linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and
still the unit didn't power up then you have an open parts on the power supply.
4.If you see that the fuse is intact , don't attempt to touch anything
because there some fatalcomponents
stored electricity enough to hurt you with a simple mistake only. I would
advice you to look for a
professional to troubleshoot
the power supply. If you want to repair it yourself make sure that you have
necessary tools and test
instrument. First check bad solder joints(re-solder all
cold solder), leaky
electrolytic capacitor(sometimes it has bulged at the top but not all, you better
have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat
sink), open fusible resistor (caused by shorted regulator
Transistor/IC), shorted zener
You may also replace the power supply board, try online like
ebay.com and shojimmy.com.
Also check if your unit is under warranty before opening the back
panel, it will void the warranty. Avail it because the manufacturer of your
unit will fix it for free or a little charge only.
Hope I helped you.
Have a nice day!
Thanks for using fixya.
