Re: NO Signal to monitor

It sounds like a motherboard issue.
Six of our 270s have experienced this exact problem.
A replacement motherboard would correct the issue.

Re: NO Signal to monitor

Make sure your computer is off then: 1- keep press and release "F8" button on your keyboard while turning your computer on. 2- you should see a black screen with some text on it. choos "Safe Mode" If you still can't see anything you need to make sure all cables are connected and are not damaged. If still have problem you need to open your computer case and fasten all cables and cards because when your son pulled the cabel this could moved your computer case unsafely and loosen the cables inside. If you still have problem this means your hard drive has been damaged due to sudden movement while it was operating.(even if it's not operating sudden movement coulds damaged the hard drive). you need to buy a hard drive and install a fresh window on it but if you can not do it. Find your local computer repair shop (Yellow page- Thumson Local ...) Good Luck Please let me know of your progress and leave me a good feedback. Kind Regards

I have nothing to plug p3 and p4 into when all on no signal

Sometimes if a VGA cable is not screwed into to both your Tower and your Monitor, it can get loose and thus resulting in no signal.
Another cause of a Monitor Displaying the no signal message would be due to the Graphic Card failing, or possibly due to the Graphic Card not correctly being seated.

Other Thoughts
Usually P3 and P4 refers to a cable on your power supply that needs to be attach to your motherboard to supply extra power.

If your P4 cable is not plugged in before turning on your computer, this will also result in your Monitor displaying the no signal message.
Keep in mind though, if your computer has not been opened or is not a custom built PC, you should not have to worry about such issues as your P4 cable should in theory be connected. However I guess safely checking won't hurt anyone.

I have a dell studio 540 desktop, I need to restore to factory settings but my monitor will not stay open. It opens for a few seconds then immediately goes into power saver mode and turns off, how can

I see two things here, but need clarification;

1) Monitor goes to Power Saver Mode, then turns -> OFF?

Sure that monitor didn't go into Standby Mode?

2) Why are you performing a restore back to factory settings?
Pick up a virus?

The monitor receives a signal. A video signal. The video signal comes from the computer.

If the monitor is NOT receiving a video signal, then the monitor will state No Signal.
This is for older monitors.

New monitors do not state No Signal anymore.
It's Power Saver Mode, or Sleep Mode.

If the monitor is truly OFF, the Power On button will Not be lit up.
Or the Power On LED light on the monitor.

Monitor power on LED is lit, or Power On button is lit?

Monitor is not receiving a video signal;

Use a monitor cable from a KNOWN to be working monitor, for a temporary test.
Use a Known to be working monitor, and it's monitor cable.

Need to find out if monitor cable is good.

Monitor cable checks out good?

Then problem is computer.

The two leading issues with desktop computer failure, is;

1) Computer is dirty inside
2) Power Supply inside computer is bad.

Please post back in a Comment.

Well we had a power outage today and when the power came back the computer went back on but instead of starting up windows the blue power button flashes. but the fans and components inside the computer...

if there is no post sound (beeps) and the pc does have a speaker you can try this first.

remove the power cable
hold the power button in for 15 seconds to clear the residual power.
replace cord and power on

if you still have the same result, then you need to learn how to reset the bios/cmos on your system.

Wont start up

Check physical connections first, check monitor cable if securely plugged in and then check power light of monitor. If power light on monitor is amber or yellow it means that monitor is not getting a signal from cpu/ tower. Try to do a power drain on the computer, remove power cable at the back of the computer and then press and hold the power button for 10 secs, after that plug in power cable again and restart the computer.Check if there is any connection if not then try to use another monitor, a known good one. If you get a video from another monitor it means monitor is already defective.

Hi , i turned on my desktop & left it so after a while the screen saver started as usuall but withing secs the monitor went blank and blinking as if there is no signal so i checked the signal cable...

your pc probably freezed up for some reason, you can turn it off by keep pressing the power button. After a few seconds it should power down. reboot the computer, he wil probably start a checkdisk and afterwards your computer should be fine. backup your pc asap, and try to find the reason for the freeze (recently installed new drivers/software?)

No signal to TFT monitor and after switch on the CPU starts automatically. Ganesh

Have you tried a different monitor to see what happens? Does the monitor actually say "no signal"?
If it says no signal then make sure the cable is connected from the computer to the monitor securely.
And in worst case scenarios, one of the RAM sticks may be loose. Just pull them out, clean out any dust and push them back in until you hear the click of the RAM locks.

Abrupt loss of signal to monitor.

May be your Video card. Try a different monitor to see if it is working. If not you may need a new video card.
