Hi

The inverter board regulates the power to the LCD backlight, it doesn't affect the display, just the light.

From my experience I would say that either your LCD cable is damaged or maybe partially unplugged, or the LCD itself is damaged.

The first step would be to unplug the LCD ribbon cable and then plug it back in making sure that it is properly aligned and well seated. Does the LCD now work? If not, try getting another cable off... you know, that auction website (I don't give them free ads) and see if that works.

If it's not the cable then you can be pretty sure that it's the LCD as you have already said that it works on an external monitor so it's not the video card.

Hope this helps.

IH252 inc monitor bottom half darker than top.


Thin screen LCD monitor brightness controls operate several fluorescent lamps called "backlights" that are positioned behind the LCD display. Typically, they're located around the edges of the screen - sometimes just at the top and bottom, and other times at the left and right edges and others still at all 4 edges.

Fluorescent "backlight" lamp, inverter & connection wiring.

The lamps are miniature versions of those sold in stores. They require a support circuitry called an inverter that convert & boosts the level of DC to AC voltage performing the functions of a ballast in a traditional fluorescent fixture.

The reason a part of your screen remains dark is because one or more of the components in the picture above has failed and will not allow the lamp to shine. Replacement lamps and inverters aren't expensive - but requires patience and the ability to disassemble / assemble the monitor (which is usually harder to do than it appears) and solder. They are available various lengths and color temperatures (you must get a lamp that is identical or it will be noticed). If this is a new monitor - you ought to return it for replacement. If used, consider the cost of purchasing a replacement (new or used) vs. repair.

I hope this helps & good luck!

Could be a loose connection, but this model is notorious for bad capacitors. Replacing capacitors is a pretty easy task, but not for everyone (takes about an hour the first time, and parts cost is usually < $10)

LG Computer Half Light, Half dark?!?!!?


Install the forteManager software that comes with your LG LCD monitor. Go to the Options tab and choose Restore which will set it back to factory settings. For some reason some monitors come this way out of the box and this was the only way I was able to solve the problem with mine.

Right half of screen is Black with a White vertical stripe


Yeah, I have this exact same problem, except my mom slammed my laptop shut in frustration around half an hour ago, so that's why it's like this. The right half of my screen is black with two colorful stripes (mostly white), but the left half is visible. I've researched a bit and found out that this is because the LCD in your monitor has burnt out, and since you don't have a monitor to attach, the only thing you can do is to go to where you bought the laptop and either get it fixed for free or return it for a brand new one (if your warranty still stands). If not, you might as well get a new laptop. I think my warranty has expired, so I'll get a new laptop, hopefully.

Hope this helps!

MONITOR LIGHT STAYS BLUE, BUT NO PICTURE


Hi
If your picture wasn't pinkish or dark at the top or bottom when it was working, then it may be the inverter has gone bad. Inverters are like light bulbs and have life expectancies on the capacitors.
If your picture was pinkish or dark at the top or bottom when it was working then you may have 1 or more of the bulbs failing.

To get to the inverter:
Remove the stand.
Take the screws out of the bottom rear edge (these hold the front trim)
The the trim then unsnaps. {Be aware of the wire to the power button board on the bottom corner}
Start at the bottom and release the trim by lifting away from the glass of the screen from the center outwards to the corners, then work your way up each side bottom to top (a pocket knife or thin putty knife will help release the catches) These sides can be really tough to pop off especially the last top clip on each side.
Then unsnap the top edge (rocking it while lifting helps)
Disconnect the power button plug or unsrew the screws.
Once trim is off, remove the 4 corner screws that hold the screen in. Then the screen will lift up.
unplug the bulbs and wire to the screen (screen plug that goes into the metal case pulls out)
then the inverter is under the center area under the metal cover
Shout if you need more info.
If you email me a good picture of the inverter , I may be able to get a better idea if it is the inverter from a visual.
