My lcd display has just a black screen


If there is no nec logo, the problem is in the power supply/inverter board, one or two capacitors open leaving a small dome shape at the top, "most common" but if power comes on the problem is "inverter transformer or backlight issue"

The only button that works is the remote power button. None of the buttons on the side of the tv work. The volume bar is always visible. The picture works when I'm watching a dvd, but the volume bar is...


Hi check to see if the volume button on the side is pushed in or sticking as this will cause all the buttons to not work as the micro thinks you are trying to turn up the button and thinks this button is depressed.

Screen is black, green light is on. Disk light comes on for a second when power button is pushed, and fan comes on briefly. Otherwise, nothing. Same outcome on AC or Battery or Both. I tried the remove-AC,...


Hi,

There are approx 6 reasons why this might happen:

  1. The backlight has gone (Find a dark place and shine a torch into the screen and see if you can see an image in the background, if you see an image then the backlight has gone) - Needs a new backlight (Engineer to remove and fit) or have a new panel fitted.
  2. The panel has died - Need a new panel
  3. A cable has worked itself loose or is broken
  4. The inverter has gone - Need new inverter
  5. Long shot, the bios has got corrupted - Engineer could re-flash the bios
  6. Long shot, Mainboard onboard graphics has gone - Need new mainboard
My personal opinion is that the backlight or inverter has gone - Either way it needs to be opened up to repair it, consult a service centre and get a quote or repair it yourself if your up for it.

Thanks

I can't get any sound out of my monitor. when I push the select I get the speaker w/music, select that.My color on th volume is green. I get no sound. I try to push the 1-2 reset button and nothing changes...


First use a try testing another source of sound, (say an Ipod or cd player) instead of your computer.

If that works the try troubleshooting the mute and volume controls on your computer.

DiamondPoint V71LCD Not displaying image


The LCD screen may be burned out. There's whats called an invertor board and there is an electronic ribbon strip on the LCD itself. If you look very carefully you can probably see a faint image on the screen. The LCD screen will need replacing. Before doing anything with this monitor, try it on another computer first and if you can try another monitor on your computer. Other than that, there really is nothing you can do but replace the monitor.

NEC MobilePro 780 Screen


A couple of things spring to mind. Have a good hard look at the screen when it goes dark. Is there still an image there but it is really dark? If so, consider that it may be a faulty backlight. It may also be a faulty ribbon cable joining the screen to the main unit, or it may be that the brightness down button is stuck and causing it to lower the brightness. The fact that you are pressing the brighness (up button I am guessing) and it comes back on, may indicate the bright down button is stuck or by pure chance you are pressurising the board in that area causing a bad contact to work, such as power to the backlight or pressure on the ribbon cable. I dont have one of these MobilePro's but I am just going on things I have seen with notebook PC repairs. Hope this helps.
