Computer Monitor is dim

First of all do the flash light test. If you can see dim picture, your monitor's Backlight Inverter board is faulty.

change the inverter if it does not work ,you will have to change the backlight bulbs or you change the screen

Disconnect the lcd from the computer. Turn on the LCD and see if it still flickers fast. If it doesn't then go ahead reconnect the lcd back to the computer. If its still flickering, then go ahead and hook it up to another laptop or desktop. If it doesn't flicker on another computer then that means there is a problems with the video card on the original computer.
If it still flickers then that means the lcd is bad and would need to be replaced.

screen is going bad which is why its flickering and has the lines across the screen. Theres a board behind the lcd and when that doesn't process the voltage properly it can cause the screen to flicker. White lines across the screen means the screen is going bad. At this point unless your monitor is under warranty, go ahead and replace it.

sad to say your monitor has an electronic problem inside that need service, maybe the ccfl lamp went out already..

A couple of things to check. First make sure that all the connections are in place. That is, the one at the PC and the one on the back of the monitor. Second - Make sure that the video card is seated correctly in the PC. Third - Replace the monitor cable. Fourth - Check with another monitor, if possible.

Hello,

The problem can be caused by 1 of 2 things either your power supply is going out or the backlight bulbs are going out. The most likely cause is the power supply. If you are willing to do a little soldering you should be able to do the repair. If you go to our web site at: www.ccl-la.com/badcaps.htm We have a section on monitor repair. Look under the Samsung 930B it is the same as your monitor.
If you don't want to do it yourself we do offer a repair service, email me if you are in need of that.

I hope this helps.

It sounds like your monitor went bad. It happens. Call around. There are a lot of deals now. Good luck.

mzsouthpole9, Yes, this sounds exactly like a SWITCH-MODE-POWER-SUPPLY problem, and/or INVERTER circuit problem. I have lucked out and repaired 3 lcd/fpd monitors with very similar/same complaint. Now here is what you are dealing with. Have you seen the new energy saving 'curlie-Q' screw-in Compact-Fluorescent light bulbs? Your lcd monitor needs white light to light-up all the pretty colors in the LCD panel. You are lucky. The SMPS in your unit is at least for now, supplying voltage to the digital processor board in your monitor. That's y u see an image on the screen. Because your Cold-Cathode-Fluorescent tubes (2ea) are not lighting-up, you now see what you see. this most likely is a SMPS failing to source voltage to the Inverter circuit which takes 12-20v dc and changes it to 800-1500v ac to light the thin, straight, horizontal (left to right) CCF TUBES. Here are your options as a consumer. Call viewsonic, see if they have a swapout program. You send them your's+$50-$90, and they send you a refurbished same model in return. Or try to find local TV/Monitor repair shop that knows forwards and backwards everything about CCF tubes and SMPS/INVERTER repair. Last thing is try to repair it yourself. Whatever you decide to do, please drop an email to me. I'm louie12fix on fixya or lmistyrel@ aol.com. Hope this info was of some help. PS Put LCD/FPD in safe place to prevent damage to the most costly part. the LCD panel!!!!

That's better.
Yep, 95% chance it is the power inverter problem.
If you don't remember the screen having a pink tint or flickering for a while or being dark at the middle top or bottom before it went, then your bulbs should be okay.
It will need at least all the capacitors replaced.
I fix many of these types on ebay.
