    Does the computer keep working when it happens, or it crashes?

I've just spent ages tracking this one down. In my case it is the protection circuit in the backlight invertor. The tubes are worn out (they are pink when they first come on) and need replacing :((.
If the picture disappears and the blue light in the ON switch stays on, you've probably got the same trouble.

Hi every one, yes had same problem with this monitor made by Proview (not Philips or Xerox) what crappy stuff pc-world/Xerox try to sell, this monitor that i am now using now came with the stock problem, 3 years old and back light switching off after 3 seconds but the LCD panel working, to check shine a torch into the display. I first checked the net no answer except check for blown capacitors, check the PSU board no visual signs of blown caps but noticed a 2 volt drop on the main supply (after 3 second approx.) that drives the inverters and the main PCB, i had a check of main components on the PCB all seemed ok using a digital multimeter. After checking the net again, a blog suggested to remove the CCFL lamps to check if they were turning pink, sign of the lamps needed changing and that the inverter protection was kicking in. After 20 minutes taking the panel apart (first time i have done this) and then removing the CCFL lamps and plugging them into the PSU board they were fine (bright white in colour) so i reassembled the panel and to my surprise the fault had cleared itself. The fault could have been a loose/badly fitting connector or the ends of the CCFL lamps arching/shorting high voltage to the metal surround or maybe the connector on the back of the panel that connects to the LCD drive PCB (two lumps of glue on each end of connector), when taking the monitor apart take note of the CCFL lamp connectors (little black dots) anyway I’m happy now as i was given it for free (freecycle uk) but i still prefer my ASUS vw19 from ebuyer.com there the best john.R UK

What is the best way to connect 2 computers to this monitor


If you have two separate computers for different purposes, such as personal and work use, you may find it convenient and necessary to connect both to a single monitor. Many monitors have dual inputs, making such a connection simple. However, you might need a keyboard, video and monitor switch to accomplish this task if the monitor lacks a second input. Dual Inputs
Step 1 Examine the back of your monitor for the presence of dual video inputs, such as a single VGA and DVI or HDMI output.
Step 2 Connect the VGA cable to one computer. Plug the other end of the cable to the matching input on the monitor. Rotate the retaining screws until tight at both ends of the cable.
Step 3 Plug the DVI or HDMI cable into the back of the second computer. Insert the other end into the monitor's digital video input. Screw down the retaining screws if you're using DVI.
Using a KVM Switch
Step 1 Ensure both computers are turned off. Place the KVM switch on your desk where it is within convenient reach.
Step 2 Locate the video output port on the back of the KVM switch. Plug a VGA cable into this port. Plug the other end of the VGA cable into the monitor.
Step 3 Plug the VGA monitor outputs from each computer into the inputs on the back of the KVM switch. Tighten the retaining screws down for each connected VGA cable on the computers and the KVM switch.
Step 4 Plug the keyboard and mouse cables into their respective outputs on the KVM switch. Plug each set of keyboard and mouse cables from their ports on each computer into the matching inputs on the KVM switch. Plug each cable in sequentially to avoid mixing them up between machines.
Step 5 Double-check that the mouse, keyboard and monitor cables leading from each computer all correspond to the right machine. Plug the KVM switch's power cord into a nearby AC outlet or power strip.
Step 6 Turn the computers and monitor on to verify the connections are correct.

Required Items

  • VGA cable
  • DVI or HDMI cable
  • KVM switch
  • Power strip (optional)

I have an asus v2225n that keeps blacking out after 5 seconds


Desktop or Laptop computer ?

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

http://www.kitchentablecomputers.com/static.php - rules


Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.


Test all power and data leads that attach to your hard drive IDE,SATA

the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty


If its a 40 pin flat ribbon type it will be the first to fail.


Even something as small as a faulty electrical fan and its lead can cause you problems

computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error.


Make sure your graphics card is securely seated with no dust built up or in the socket

if you remove your graphics check the socket to make sure its dust free.


Restart your computer then reinstall it this should activate found new hardware wizard


Check the VGA cable connection running from the computer to the monitor.

This cable must be completely inserted into both VGA connection ports, otherwise the video signal is not going to reach the display.


Disconnect the VGA cable from the computer and monitor, then look at the metal connectors on both ends.


If you are missing connection pins, the video signal is not going to transfer between hardware correctly.


Examine the power connection on the monitor.

If the monitor is not receiving power, it is not going to turn on.


Turn off the monitor for a few minutes, then power it back on.

Like other computer hardware, the monitor may not initially turn on correctly.


Move the mouse and press the "Enter" key on the computer keyboard.

If the computer is in sleep mode, the monitor is going to appear as if it does not have any display.



Hope this helps

Why does my monitor have a dull display?


not it isn't the card
go to control panel , display and personalization, click on the display , click on the monitor (1 or 2) and adjust the pixel size by sliding the knob to the desires screen size
click apply and ok
after a few minutes you may get a message saying are you happy with the setting --will revert back in 10 seconds ---you just press apply or ok and that saves the setting

My dell gx260 ligth come green if i turn it on but for a few mins time it turn orange why


Do you mean the monitor's power light starts green and then turns orange when you turn it on? Most monitors will go to a power saving mode when they do not get a signal from the computer.

The Dell GX260 has a green power light when on. When the computer is off, the light is off. If it is green and blinking, then the computer is in a power saving mode.

Diagnosis: start with the obvious: is the monitor cable plugged into both the computer and the monitor (if not permanently connected to the monitor)? Are you connected to the active port? (You can add a video graphics card in most desktops. The motherboard video port usually needs to be disabled to use the card ports. If you plug in the monitor cable to the disabled port, it won't work.) Is the monitor set to the correct input? (This applies if the monitor has several ports. In that case, there will be a Source or Input button on the monitor.) Is the computer on? The GX260 has the power button on the front. (Other computers have the power button on the top.) There is also the power supply switch on the back which needs to be on.

Next try a different data cable between the monitor and the computer (if you can). Try a different monitor. If a second monitor works, than the monitor has a damaged main board. If the second monitor doesn't work, then the video graphics adapter has probably failed. Replace the add-on card, if in use, then boot in the safe mode to remove the old graphics driver. Then install the correct driver for the graphics adapter.

Note: the computer and the monitor should both be off when you connect the cables. Then turn on the monitor first and set it to the correct source before turning on the computer.)

I hope this helps.

Monitor displays the PC screen but switches off within 10 second


Unfortunatley your monitor is going out. I just had that problem. My sceen would come on, but after about 10min. it would blink off and turn black. I would have to hit the off button on the monitor, then turn it back on. It would work fine for a few minutes then black out again. I got a new/used monitor where I no longer have that problem.

I did check to make sure my hybernate was not activated, it wasn't, I had it set to never turn off.

Good luck.
