If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed ACER monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

When monitor is turned on, it flickers 3 times and then goes blank


Does the computer stay on or switch off?
If the computer stays on and the monitor completely switches off then it's a monitor power problem.
Make sure all connections are securely connected.
If the computer also completely switches off then it's more likely to be a computer problem.
If it's a monitor problem then the monitor will have to go to a monitor repair shop.
If the box does switch off then let us know to continue to troubleshoot.

Monitor goes blank


Try restarting the computer in Safe Mode and then check. In case it flickers in Safe Mode too, then the LCD screen might be damaged and you might need to replace it.

Sumsung 930b goes dim,and flickers after about 3 min.


This sounds like the inverter has gone bad. If the bulb were bad only, you would see a faint image on the screen with a flashlight.

The problem is on this monitor, it will probably cost about $100 or so to take it to a shop to get it fixed, and that is nearing the cost of a new monitor.

If you are a little bit handy, and can disassemble the monitor, you can replace the inverter. The hardest thing about this, is getting the monitor faceplate open. Just use something firm and softer, such as a nylon spudger (this is something you can find online) or you can carefully use a thin scredriver. You just have to be careful, those cases are really tight.

Here is a good guide for general ideas on how it is done.

Problem with monitor


Hi.
Are you able to see a slight image on it at dusk and maybe with the help of a flashlight. since your blue light stays on the video board, may be okay.
It sounds like you have bad capacitors on your powerboard or possibly a burned out transistor on the inverter.

Only way to really tell is to open it up.
If you unplug the screen to video board ribbon, you may notice a different effect in the screen lighting.
There is a chance one of your bulbs is creating a problem
Should the screen happen to light up all white, then your power board and inverter are okay and the problem may be in the video board.
If it looks pinkish or dark or flickers then the bulbs or a bulb may be the issue.
If it flashes on then goes off, it's in the power or inverter board.

Flickers and goes black


No it is not a backlight it is the inverter board which sends power to the backlight most likely cause is bad capacitors on the inverter board. this wil require soldering to repair backlight is even worse it requires you to disassemble the lcd unit. if you are gong to ope up the lcd monitor look on all pcb boards for deformed (blown) capacitors replace those with identical ones from yur electronics shop9they must be exactly the same mfd (Microfaradays) and Voltages

The Monitor Goes on and stays steady Indicates that the Power cable to the Monitr is Just fine.
However,If the Monitor Display flickers or Goes Off and on often then it is a Problem with the VGA cable.(The Big blue Cable with 2 Screws holding it)
Unplug it and Make sure you connect it secure and tight the second time and you should Be fine.
