I have sam 51on lcd moniter with dim display problem


The screen displays is dark/ dim because there is no backlight.
There are two parts responsible for lighting the display. First is the CCFL (Cold Cathode Florecent Lamp), which is the back light and the second is the Inverter board, which provides high voltage to the CCFL. Either of the parts can be faulty or in some rare cases both.
In most of such cases that I received for repair, it was Invertor. Inspect the Invertor for any apparant physical damages (burnt coil or circuit components etc). Inverter can be checked by disconnecting the present CCFL and connecting a fresh/ working CCFL (Backlight) before actually removing the CCFL as it is difficult and unnecessary to take it out if its not the fault.

I SUGGEST THAT YOU SEEK PROFESSIONAL ASSISTANCE FROM AUTHORISED SERVICE/ REPAIR CENTER FOR REPLACEMENT OF CCFL OR INVERTER.

Hope it helps! Good Luck!

My monitor on my Dell laptop went completely black while I was on it. I have tried turning it off and back on, and the monitor is not working at all


You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight. It could be a faulty inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out; usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Screen is dim barely can see desktop in background


Usually this is a problem with the backlight, or inverter. Most of the time the inverter is the problem which is a pretty cheap fix. If its the backlight, then you will have to replace the lcd, which is much more expensive.

Normally this is caused by the power inverter for the lcd2.gif. It is a small circuit board right below the lcd, that powers the backlight. If you take off the front bezel of the laptop you should be able to see it, it will have a 2 wire power cord coming out the one end, and another plug in2.gif on the other end with several wires.

Check ebay for a replacment but make sure you get an identical model as the one you have, as they are very specific to each laptop. The inverter will have the part number written on it.

Dim display in samsung monitor


When the LCD monitor display is dim or flickers and or has a black screen then the fault is usually a faulty inverter or the CCFL lamp. When you look at the screen at a sharp angle and you see a dim image then it is a backlight problem and it is caused by a faulty inverter or a CCFL lamp.

Very Dim display


If you have tried all the usual adjustments (brightness etc), then the inverter board or the backlight itself is bad.

It's pretty hard to tell which one it could be, given as they are both related (the inverter board powers the backlight)

I had that happen to a few 192N's, and it was a bad inverter board in both cases.
