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

My computer starts up but the screen sa ys no signal


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.


To fix this problem, you must obtain a new VGA cable (at any computer or electronics store) to send the video signal.


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.

Tip

Is your hard drive or monitor randomly switching off after a few minutes of...


This problem could be that your Power Options in the Control Panel have been switched to "switch off the component ever now and then to save power". To change this, do the following:

1) Navigate to the Control Panel by clicking Start and then Control Panel. Then double click on Power Options as shown below circled in red.
slasher_x_14.jpg
2) This will then display the Power Options window as shown below.
slasher_x_16.jpg
3) Once you have opened the Power Option Properties, under Power Schemes select the one that best suits your PC system.
slasher_x_15.jpg
4) Then you can select whether or not to switch off your monitor and/or hard drives after a period of time when it is not being used.

If you have your PC on most of the time then I suggest you select Never as the turn off option for both your hard drive and monitor. If you are using a laptop the turning off the hard drive and screen can however save on battery power when the laptop is not in use.

If your problem persists then it might just be as simple as a loose connection, make sure all hard drive connectors are firmly inserted and that your monitor display plug is correctly plugged into your display card or onboard display correctly.

If your hard drive persists with this problem then it may be a faulty dive. I suggest you take the drive to a PC technician and have them check if it's faulty or malfunctioning.

If you can faintly see your desktop background on the monitor that switches off then check my tip about LCD backlighting issues: http://www.fixya.com/support/r6836567-lcd_monitor_displays_background_fine

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.

My HP Pavilion 1903 monitor keeps going to sleep every time I turn it on


check in your monitor menu to ensure there is no energy save mode set. press the menu button on your monitor and check the settings. ensure that your pc also does not have an energy save setting set. e.g if the mouse or keyboard are not touched for a specific time e.g. 1 minute then switch off monitor to save power. make sure that such settings are not switched to on in your pc settings. if this is a new monitor and this was not a problem with your old monitor then suspect the monitor settings if the monitor and pc are both new. then suspect both settings. if possible test the monitor on a second pc or laptop to see if problem persists.

My pc does not give display ? Why


Time Required: Testing a monitor could take from a few minutes to much longer depending on the cause of the problem Here's How:
  1. Check to make sure your monitor is on! Some monitors have more than one power button or switch - check to make sure they're all switched on.
  2. Check for disconnected monitor power cable connections. Your monitor might be working fine and your only problem may be a loose or unplugged monitor power cable. Note: A disconnected monitor power cable could be the cause of your problem if your monitor's power light is completely off.
  3. Check for disconnected monitor data cable connections. Again, your monitor might be turning on without a problem but no information can get to it because the cable that connects your monitor to your computer is disconnected or loose.
    Note: A disconnected monitor data cable could be the cause of your problem if your monitor's power light is on but is amber or yellow instead of green.
  4. Turn the monitor's brightness and contrast settings completely up. Your monitor might be showing information but you just can't see it because these display settings are too dark.
    Note: Most monitors today have a single onscreen interface for all settings, including brightness and contrast. If it turns out that your monitor isn't working at all then you'll likely not have access to this interface. An older monitor might have manual knobs for adjusting these settings.
  5. Test that your computer is working correctly by connecting a different monitor that you are certain is working properly to your PC. Your monitor may be working fine but your computer might not be sending information to it.
    • If the new monitor you connected does not show anything either, proceed to Step 6.
    • If the new monitor you connected does show information from your computer, proceed to Step 7.
    Important: When testing with the new monitor, make sure you use the data cable that came with it and not the one from your original monitor.
  6. Determine why your computer isn't sending information to your monitor. Since neither monitor works, you now know that the computer is not sending information to the monitor. In other words, you've proven that your computer is the reason that nothing shows up on your monitor.
    Chances are your original monitor is working fine.
  7. Test your original monitor with a monitor data cable that you know is working. It's possible that the monitor itself is working properly but it can't receive information from the computer because the cable that connects the monitor to the PC is no longer working.
    Note: If possible, test using the data cable from the monitor that you successfully tested with in Step 5. If not, purchase a replacement monitor data cable to test with.
    Note: The data cable on some older monitors are permanently connected to the monitor and are not replaceable. In these cases, you'll have to skip this step and proceed to Step 8.
  8. Replace the monitor.
    WARNING: A computer monitor is not a user serviceable device. In other words - do not open the monitor and attempt to repair it yourself. If you would rather have your dead monitor serviced instead of replaced then please let a professional do it.

My monitor screen is ok for awhile but suddenly turns a dull yellow color. I just bought it a few months ago.


Hi,
you must adjust the display settings in the software program that was being used to change the display setting.
  • If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
  • Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
  • If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
  • follw the another steps-
  • Replace the monitor power cable.
    1. Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
    2. Replace the video cable. Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
    3. If the monitor does not work after replacing the cables, replace or service the monitor

    My computer is an Acer Aspire ASE-360-U-A3503 desktop computer and I still cannot get the power up button to shut off no matter how long i press on it. Then the monitor cable connector on the CPU is not...


    You seem to have two problems here: The power button and the video connection.
    It should take 4 seconds of continuously holding the power button in for the PC to shut off, unless the settings under Power Saving say that doing this action should have a different outcome. Check your settings. If all is correct and you still cannot turn the machine off, you may have a deffective toggle switch. This is something you can get at Radio Shack or other electronics store.

    Regarding the video connection: There's a set of buttons on most monitors where you can choose the input source. Your monitor has probably been set inadvertently to receive a DVI signal while it's connected via a VGA cable, or vice versa.
    Good luck!

    Dell OptiPlex GX260 PC Desktop keeps switching its self on, can any one help, i click start - go to turn off computer - then turn off, the pc then shuts down, then a couple of hours later i hear the fans...


    Have you gone into the BIOS to make sure there aren't any power managment features? Do you get the same thing happening if plugged into a different wall socket? Sometimes bad power surges can cause this problem. Other issues have been known to arise from motherboard problems. Or NIC power settings...strangely enough...a quick way to test if it's NIC related might be too unplug any cables from the NIC to see if it stays on or not? There are power settings on NICs in advanced settings. Let me know if any of that helps and remember to rate the solutions. Thanks!

    Monitor not coming on - Packard Bell Easynote R4650


    It's a dreadful way to start a day - you press the power button on your computer and nothing happens. Do not fear because all may not be lost! Follow these simple steps to determine why your computer won't turn on.

    Note: It is very important to troubleshoot any issue beginning with the most likely and easily testable problem so be sure to follow these steps in order.
    Difficulty: Average
    Time Required: Anywhere from 10 minutes to a few hours or more depending on why the computer won't turn on
    Here's How:

    As silly as it may sound, the number one reason why a computer won't turn on is because it wasn't turned on! Before starting a sometimes time consuming troubleshooting process, make sure you've turned on every power switch and power button associated with your computer:
    Power button/switch on the front of the computer's case.
    Power button/switch on the front and/or back of the monitor.
    Power switch on the power supply on the back of the computer.
    Power switch on the power strip or surge protector (if you have one).

    Verify that the power supply voltage switch is correctly set. If the input voltage for the power supply does not match the correct setting for your country, your computer may not power on.

    Check for loose computer and monitor power cable connections. A loose or unplugged power cable is one of the top reasons why a computer doesn't turn on.

    Perform a "lamp test" to verify power is being provided. Your computer isn't going to turn on if it's not getting power so you need to make sure that the power source is working properly.

    A damaged power supply could be preventing the computer from being properly powered.

    Do a quick test of the power supply by holding your hand behind the power supply fan located at the rear of the case. If the power supply is working, you should feel air from within the case blowing against your hand. If not, you may need to replace the power supply.

    Tip: Is the power light on the front of the computer's case on? If you've turned the power switch on but the light is off, this is another good indication that the power supply is the cause of this issue.

    Over time, internal components and the cables that connect them can wiggle loose which can often times result in a computer unable to power on. Try reseating the following and then try to power on the computer again:
    Reseat the internal cables
    Reseat the memory modules
    Reseat the video card
    Reseat other expansion cards

    Reseating the CPU may also be necessary but should only be attempted if the reseating of all other components is not successful. This is due to the fact that this process is a little more involved and can run a small risk of damage to the CPU. This isn't a big concern if you're careful, so don't worry!

    Check for causes of electrical shorts in the computer case. This is often the cause of the problem when the computer powers on for a second or two but then powers off completely.

    Most monitors have a small light next to the power button that can change between various colors. If the screen is blank, this light is your main source of information about the monitor.

    If this light is not on at all, double-check the power switch and connections (Steps 1, 2 and 3) and also make sure the monitor cable is securely plugged in to the video card port on the back of the computer case. If the light is still off, replace the monitor. If it comes back on, try starting your computer again - a loose or unplugged monitor cable may have been the issue all along.

    An amber or yellow power light simply means that the monitor is not receiving any information from the computer. In and of itself, this doesn't tell us much.

    On the other hand, if the light is amber or yellow, the computer power light is on, and the hard drive is active (making familiar sounds and the hard drive activity light on the computer case is blinking), the computer is probably starting normally but the video card is not sending information to the monitor. Replace the video card.

    Beep codes (see Step 11) usually sound when a video card has malfunctioned but this is not always the case.

    Is your computer making a beeping sound? Sometimes a computer will turn on just enough to play a series of beeps from the speakers.

    These beep codes play in particular sequences and represent a specific problem that your computer is having. Troubleshoot the beep code to figure out what it's saying and then service the computer as necessary.
    Tips:

    Still can't get your computer to turn on? Let a community of computer support enthusiasts help out! Post the details of your problem in the Focus on PC Support Forums.
