**Copied from another product however my problem is the
same. No picture what so ever. even when shining a light into the screen. would
this be an inverter issue? **
Hi, Whenever I turn on my monitor it displays the computers
output briefly (~half a second) before going blank. I have tried the monitor on
two other computers with the same result so it is definetaly not a computer
problem. The power light on the front of the monitor stays green when the
screen goes blank. Whenever I turn the power off and back on again the exact
same thing happens.
**PLEASE NOTE - This solution applies to ALL LCD's
but NOT CRT's**
It's a very common problem with all LCD monitors
LCD's use four small Cold Compact Fluorescent bulbs to back light the display.
(thats what gives the LCD it's brightness allowing you to see it)
The inverter board runs these lights and when they go bad they will typically show
symptoms like you have or the monitor power light comes on and you have either
no display or a very dim display.
If you ever have one that has no display but the power light is on you can
check by shining a flashlight directly into the LCD from the front (right into
the screen) if you can see an image then it's either the inverter board (most
likely) or the CCFL bulbs have gone bad.

Re: wont stay on
IF there is no display even with a flashlight, the P/S board is malfunctioning. Bad capacitors or LCD driver board circuit. Mine did this and it was bad caps, 4 of 8 were bad and a burned out chip on the P/S board.

the monitor may be losing the back lite. take a flash light or bright light and shine it at the screen after it goes black. can you see a faint picture? if so the back lite has failed. usually the cost of replacement exceeds the cost of a new monitor but there are a couple of web sites that detail the replacement of the "ccfl" cold cathode flouresecent light.
mark587, Did you shine a very bright flashlight 1" from the screen to try and see the WIN-desktop ?? Even though the screen appears BLACK. Your words above said: JUST CAN'T SEE IT Did you really NOT see anything? Have you seen any of the longer video clips of "LCD Monitor Disassembly" on YOUTUBE? Some BLACK screen "symptom" lcd displays can be repaired for less than $10 in parts. Capacitors! Also check videos on lcd repair. Then get back here to fixya and I or any of the guys can help you decide what to do with your display whoose screen is now dark and lifeless. After doing the YOUTUBE thing you may even tell us what you will do!!! Hope this was helpful. Yes we do want to hear back from you. please rate this response on fixya. I'm louie12fix on fixya or lmistyrel @ aol.com. Bye for now.
From what you say there is probably not much you can do with it, the parts inside are SMD, to small to work on. If you could still see txt on the screen when you shine your torch, it could be fixed by replacing the back lighting PCB.
hi, there is some loose contact in the connection. Take out the cable end from the VGA socket and check the pins inside the socket for any bend inside the socket. Reconnect it, tight the connector with the socket bolts. If not solved, try for any loose solder or wire breake.
It is probably the ccfl inverter board that has gone out. It is what drives the fluorescent lighting that gives your monitor a picture. One way to test it is to shine a flashlight at an angle on the monitor while the computer is on and if you can see the picture very faintly, it is the backlighting not coming on. It could be the bulbs, but more times than not it is the inverter. You can usually find them on ebay along with instructions.
Hi you can inspect that what's wrong with your monitors. After you turned it on and the
screen went black, you have to check that 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. This is because of the lamps
inside screen. Some of them were broken and it is very easy to replace. 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. Hope this help!! If
anything I can help you with, feel free to let me know. Thank you,
When the picture disappears again take a flashlight and shine it in the bottom left hand corner where the Windows Start button is located. If you can see a faint image then your back light is failing. If that?s not the case the next step would be to attach another monitor to your computer to see if the problem disappears. If it does that points to the monitor, if it doesn?t then we need to take a look at the computer itself.
Let us know what you find out and please don?t forget to rate this posting.
If you have the pc on and the monitor light stays green, take a flashlight to the screen. If you can see the images while shining the flashlight into the screen, they will be hard to see but they will be viewable, then its most likely the back light. The vx900 takes 4 bulbs and they are about $12 US each. Anyone who knows how to solder should be able to replace them.
