Question about HP Pavilion a1720n PC Desktop

1 Answer

When I turn on the pc I get no picture. The monitor stays in power save mode and if I turn of and then on the monitor it says no signal from pc. I got a pci express video card and pluged the monitor in to it but when I turn on the pc it still has no signal to the monitor. I am unsure how to get the bios to recognize the pci video card.

    I don't think it is the video card now. When I press the power button the keyboard lights flicker but none stay on, I hear the hard drive working but not long enough to start Windows. It is probably posting a message but I am unable to see it. I do have an onboard video card that I thought was the problem first and that is why I got a PCI Express card but it won't display either. I tried removing around and even replacing the RAM chips but I still get nothing.

Welcome to Fixya

No signal usually tells you that the video cable is not properly plug in at the back of the computer or the video card has gone bad. If your computer has a built video card, you can use that one to test the PCI video card if its malfunctioning. You might need to take out the PCI video card inorder fro you to use the onboard video card.

Please reply to this email for any update.

Thank you for using Fixya!

    you have two problems there. It might be power supply that is not supplying enough power to the motherboard. Wors scenario is, it might be the motherboard has the problem.

Hi. I have a FLATRON W1934S computer. Every time I switch it on it says "power saving Mode". How can I fix it?


Hello, I didn't understand the problem.
1.After switch on and it goes to power saving mode , which can be visibly seen by changing the color of power led from green9or blue) to yellow.

First thing to be done is when it goes to that state "power saving mode" remove the video VGA cabl , and if the unit gives video message "no video signal" which stays for a while and usually goes again to power saving mode , this is OK,
So if there is no video signal on input it should work like this. so you have to check you PC.
Another way is to use laptop or other PC to check the monitor itself.

Hope this helps a bit

Monitor goes into instant power saving mode and will not display a picture


I doubt the monitor is the problem. I think your pc is not booting up and sending a signal to the monitor and it goes into that mode because of no signal.
Try a different monitor if you can or take your monitor to a friends house to try it on a different pc.

Monitor stopped working...checked all connections...light won't stay on green. bought a new monitor to replace it and that monitor says "no signal". is this a problem with the dell computer and not the...


Your monitor is going into power saving mode. When it receives no video signal from the computer, it will stay powered for a few seconds before giving up and presuming the PC is off hence why it stays green for a while, then goes orange.

The problem is with your PC not the monitor(s)

In power save mode


The monitor is not receiving signal from the computer. Is the power light on on the computer? If so - press and hold power button on computer until the power light goes off, then press again to restart. If the computer starts and you still have no picture it is most likely a video card or motherboard problem.

Computer monitor comes on for 1 seconds, flashes "analog power save mode" and then goes black.


Most monitors will say "Power save mode" when they can tell through residual voltage that the signal lead is plugged into a machine, but there's no picture being transmitted. The four states of a monitor are:

* Off entirely.
* Switched on, plugged into a computer but no video signal being received - usually displays "analog power save mode" or "digital power save mode" for a few seconds, then blanks. Comes back to life the moment a video signal is received. This state is the default in full power saving mode.
* Switched on, not plugged into a computer. Some monitors don't display anything, some go into power saving mode, some fly "CHECK SIGNAL CABLE" or a similar message around the screen. Picture is restored when the signal cable is plugged back into the computer
* On fully, receiving an image, and displaying.

Hope this helps.

My desktop pc has gone into power save mode


Turn the whole pc off then back on. If the LCD stays in power save then I would try a diffrent monitor on the PC. If that fixes it the the monitor is probably stuck in power save. Check www.lcdrpair.us for parts and instructions.

No picture on the screen


Hi,

I have this Panasonic PanaSync SL70 17'' monitor, I don't use it often. It is still in very great shape. However, I tried to turn it on yesterday, I got a black screen. The power LED is on and I can hear the relay is clicking when signal received. I tried to remove the signal cable, I can see it turns to power saving mode. It seems that everything works fine except no picture. I am if the transformer is gone, but not sure. I am wondering if you can help?

Flatron LG monitor safe mode


Your monitor goes to Power Saving Mode when the signal it is receiving is not correct. In all probability this is not a problem of the monitor itself, rather you should check the connections and the computer the monitor it's connected to. For example you could try a different RGB cable and try it in a different computer.
