Question about NEC Computers & Internet

1 Answer

I have a lcd 195vxm hooked up to a laptop because the laptop screen failed. It has been working fine for several months, but now it comes on and says "video signal 1 dsub no signal". That is the same message it has always said, but now it just goes back into standby mode (yellow light on power button) and won't stay in active mode. I have rebooted, unplugged for a few minutes, but it hasn't helped.

Go to safe mode and decrease the screen resolution,

if still doesn't help go to safe mode again then go to system restore under system tools, restore back to early good restor point

Cut laptop on and off several times. Now screen is black and will not come on. What can I do to make screen come on?


On a Dell laptop, you can run a screen check by holding "D" and pressing power. I dont know about other brands. However, you can tr hooking a screen up to the external video port. if It comes up, then you likely just have a bad LCD screen or perhaps even a bad cable connection. If not, it could be a more severe issue called "no post". A no post issue could be the result of a loose memory chip, or failed battery charger (resulting in dead laptop). If you know the ram is good, and the laptop is taking a charge, then the no post issue could be a bad system board or CPU, which sadly, is far more severe.

Laptop LCD/Display Problem, Green and Pink Tints???


Their are a couple things that could be causing this, My first thought is that the screen its self is damage. A LCD screen is composed of millions of tiny pixels so when some fails others will still work.
That other thought is that the GPU or video device on the laptop could be failing and creating video problems. Have you tried closing the laptop and opening it agian, this would help rule out a bad cable connection.

Check monitor is set to correct input (VGA, DVI, HDMI) if it goes to sleep instantly.


Otherwise screen resolution is set too high. Boot into safe mode by pressing F8 during boot. Login and lower screen resolution.

Hi there,

In your situation, you have the possibility of several different problems.

1. Your "Screen Inverter" is failing.
2. Your screen "LCD Panel" is failing
3. The "Video Controller Chip" soldered permanently to your motherboard is failing.

The first step in troubleshooting these problems would be to take your laptop to a friend's house who is using a desktop computer with a separate external monitor. Hook your laptop up to the external monitor and see if it displays normally on that monitor. If it does, you merely need to replace both the Screen Inverter and LCD Panel of your laptop and you'll be fine.

If, however, your laptop will not display on an exterior monitor, it means that your video controller on your motherboard has failed and you'll have to either get a new motherboard installed or consider replacing your laptop.

I'll be rooting for # 1 or 2.

Kind Regards,

Selk

This is due to loose connection which could happen after a period of time between the screen to the laptop.
Solution:
You can use another LCD screen as you secondary screen which you need to hook up to your laptop onto the blue connector (vga connection) or get the laptop screen replaced altogether

Try the "Display Swap" button (usually a Fn key). Some of these have several choices each time they are pressed, e.g. Laptop Display, External Monitor, Both, and NONE!). Hope this helps. Ian.

Sounds like the lcd screen has gone out . Hopefully you still havea warranty on it. But a good way to test if its the lcd screen or the graphics card is to hook it up to a external monitor and see if the pitcure comes up if it does then its the lcd if it doesnt then its the graphics or motherboard itself
