There are several reasons why there's no picture. It could be the video card, monitor cable or it could be the monitor itself.

Try connecting the monitor into a known working computer to make isolate the problem. If the monitor works on another PC, then the problem could be your video card.

But if the same problem occur while on another computer, try replacing the monitor cable. If that did not help, then the panel could be shot. We cannot say that it's the power supply board because there's a power. So it could be the panel itself.

Good luck and have a good evening!

No picture on my Gateway monitor My Gateway FPD 22755W TFT LCD Monitor powers up but has no picture. The blue lights on the lower righthand side come on. It makes the little banjo strum, but absolutely no...


First of all disconnect the power & unplug the video cable from the back of the CPU & Monitor. Power-on the monitor & wait 10 secs. If the Monitor is functioning correctly, a 'No Signal' message appears & sometimes keeps bouncing around like a screen saver motion. This means your monitor is OK, if no signal message is not showing then either backlight or inverter(power) input has gone KAPUT. Replacing either or both may not turn out to be a cost effective soln. However if the damage is only in the cable then simply replace it or use the HDMI port..........................Sodeep63

How to take the cover off an LP2407


There are 3 screws along the bottom of the monitor, remove those along with any screws where the stand is attached. There are 2 slots on the bottom where the halves of the monitor come together; with a screw driver, you can use those for leverage. With another small screwdriver on the sides of the monitor where the front shiny cover, and the duller back case come together, pry the shiny piece away from the back cover and lift. It is a very tight snap fit, you have to go slow and coax it off.When you get the front cover started you can usually pull it off with your fingers by lifting up. Be very careful Of the front panel switch ribbon cable it is very easy to break. Hope this helps

I'm having trouble with my Gateway monitor coming on model # LP2407



Steve
there are so many things that can go wrong, the best thing is to take/send to a professional , or i can take a look at it.
many repairs are the standard capacitor replacement, but many others should be done by someone that has a bit of background in electronics to test all the circuits. For more help i can be contacted at Sprint6@zoominternet.net.
if you would like i can test the unit, at no cost to you, and give an estimate of repair cost once i have evaluated the condition of the unit.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
