When i switch on the computer, the only thing that appears on the screen is "power save mode on". i have checked all the cables, i changed monitors, but no solution for the moment thanks for...


Im assuming the monitor worked OK until now. The two things I can think of is, First is the cable from the monitor to the computer is either not connected tight either on the monitor side or the computer. The second thing I can think of is a bad video card. I think the monitor is ok because your getting the power save mode on the screen.

I hope this helps you out, if it does please leave me some positive feedback.

My monitor, keeps saying it is going to sleep. VGA says no input signal, as well as DVI. And I know nothing about computers


If there is no output on the screen, check all you cables and connections and ensure they are snug and secure. If there is still a problem, it is possible your video card is to blame. As a diagnostic step, try hooking the monitor up to a different computer. Or hooking up another monitor to your computer. This will help eliminate bad cables and connections. If a different computer works on your monitor, then you most likely have a bad video card. If you monitor still will not work on any computer, then you most likely have a bad monitor.

Getting black horizontal lines across the screen. It started off as an intermittent problem, now occurring more often. I changed the video card and the power supply tests fine and I changed the refresh...


I would test the cable, use it on a different monitor or try a different cable. That is the only other thing to check, otherwise it definitely is the monitor.

New monitor flickers when hooked to computer


Hi!

There's a few usual culprits for this problem.

  1. Check the cable. Swap to a different cable if possible to rule that out.
  2. Check the refresh rate of your monitor. Most monitors have options for this via a Menu button on the screen itself.
    If you find it, change it to 60 hertz
  3. Check the refresh rate of the monitor from your operating system/video card's software.
    In Windows, right click on the desktop, click Properties, then the Settings tab, then Advanced. Change it to 60 hertz if it's anything different.
It could be faulty but hopefully not.

Couple of things there to try...let us know how you go

My packard bell lcd monitor shows orange then sometimes green light but has totally black screen. If power supply giving insufficient voltage would this cause above problem?


> insufficient voltage cause ?

Well, anything is possible, but other things are more likely:

1. loose connections of the "data" cable between the monitor and the computer's video-card;

2. an electrical "short" in the data-cable;

3. a "dying" video-card.

So, try the "free" stuff first:

Check the connections.
Try a different cable.
Try connecting the monitor to a different computer (laptop?).
Try connecting a different monitor to your computer's video-card.

Then, consider buying & installing a new video-card.

Monitor wont turn on, light flashing


A number of things can cause this. Incorrect BIOS settings, cable problems, a faulty monitor or problems with your video card.

1) If you can change the monitor cable - do so
If it worked, great else - carry on....
2) If you have two monitor inputs on your computer swap the connection to another input, only if it is on another card. If it worked great, else carry on.....
3) Try a different monitor to see if the same thing occurrs... if it does then it is either video card or BIOS
4) Reboot your computer and watch the screen - it will tell you to pres a key to enter BIOS or setup - do so.
Switch of cacheing of Video RAM
and Disable ACPI settings - all power and green energy settings. If that does not do the trick then it is most likely your video card - or your monitor... borrow a monitor and video card for ten minutes and you will find out which is the problem

Screen goes pink and green starting with a few pixels


Best thing to do, try a different known working monitor to hook up to the computer. If the screen works and doesn't change colors then you know its the original monitor that is bad.

If you hook up the known working monitor and the same problem happens then you know its the video card that is bad and the video card would have to be replaced.

Led flashing no picture


disconnect the signal cable from the computer. if it shows color bars, it means your monitor is ok and your video card is faulty. if it still does the same thing. you need to reseat the video card if its not integrated.

hope this helps.

Monitor turns on then shuts off in seconds.


check your video card connections. make sure that your monitor cable is attached firmly in place.Also make sure the video card is fully pushed into the slot on the motherboard. Sometimes because of heat the card can pop out of the slot. Sometime this is just enough to barely work and then stop.

Syncmaster 245B Monitor Shivering horizontal lines


Which type of video connector are you using? VGA or DVI?

If you are using VGA, the horizontal line could be due to interference, like from an electric motor (fan) near the video cable.

Other thing to try is to change the refresh rate. In Windows XP: Control panel --> Display Properties --> Settings tab --> Advanced button --> Monitor tab --> Screen refresh rate. The default ot 60Hz for LCD monitors. Bump it up to 75Hz. That could give a clue to the problem or maybe even fix it.
