I start my computer and the monitor says no signal and even after i shut down the computer the screen stays blue and says no signal. any solutions?

Monitors shut down when they are not receiving video signals ... to save power. Even if the computer was taking to long to initialize the video card, the monitor would simply come back on ... so your question probably should be why isn't your video card powering up. Many reasons for that, but bad mainboard, bad video card, bad power supply are probably the most common ... not necessarily in that order.

Close windows down. Wait 15 - 20 mins, then power monitor up but NOT windows. Screeen should say "NO SIGNAL in centre. If t does not, wait five mins If still no display shut down and wait another 5 mins. Then start monitor un ANDt windows.. All should be OK now, If not shut EVERYTHING down and disconnect from mains ovrernight. (PC riouter/modem,,,, EVERYTHING . 12 hours later, re-connetc in THIS order - 1.) MONITOR 2.) PC 3) ROUTER/MODEM Should be OK now.

Ok, another words, monitor powers up for few seconds and shuts down by itself. If green LED on the front panel turns off as well or stays on?
If stays on, then inverter turns into protection mode because of old backlight lamps.
If it turns off in same time with an image on the screen, then there are some bad electrolytic capacitors in the power supply.

You got a short circuit in one transistor located at the inverter area. The transistor is acting like a conductor and not shutting down the power to the back light inverter. If you are a technician and want to fix it, look for short circuits in transistors.

Good luck.

Replace the entire DAC board (board with power suplly going into it) for easiest solution.

If you are turning off your computer by pressing the front panel power button, it is probably just putting Windows to sleep but not shutting the computer off. If your computer has Windows Vista, the default is to hibernate and not shut down even if you shut down through Vista. The "power save" message you see is coming from the monitor, which is letting you know it isn't getting a signal from the computer anymore but the power is still on. Windows will start up again from sleep mode if someone or something moves the mouse or presses a key.

The solution is to make sure the computer is actually shut down. In Vista you can do this by clicking the arrow near the power icon on the Start menu. This gives you the option of shutting down instead of hibernating. In XP, shut the computer down using the start menu shutdown option instead of the computer power button. Then the power will shut down completely.

It sounds like your computer has been having some trouble for some time. My hunch is that there is nothing wrong with the monitor at all.

Usually, when you see this warning on the screen that there is no signal, the monitor is trying to tell you that it cannot talk to the computer. This means the computer either a.) will not boot or b.) your video card in the computer has stopped working.

Does your computer make all the usual noises when you start it up? Can you hear the hard drive clicking and the fans come on?

Have you reseated the video connection on the back of the tower?

My guess is that something was going out before and it is now gone. The first place I would look to diagnose this problem is the hard drive.

Hard drives fade to fail sometimes, and when they are fading, the entire computer becomes painfully slow.

Hope this helps
good luck

How old is this thing? Mine is about 4 or 5 years old... junk it!

I will assume the monitor is staying on during the boot process all the way until Windows loads.
If that is the case, then...

• Start the computer
• wait until the initial bios/logo screens for your motherboard go away.
• Press F8 to get the Windows recovery boot menu
• If you see the Windows Logo you would normally see then press rest and try again.
• In the recovery screen, select SAFE MODE
• Boot into Windows and uninstall your video card.
• Reboot the computer the normal way through the start menu.
• When your PC starts back up it should then reinstall the video card, and set itself automatically back to 60khz as default.

Let me know how you go =)

The problem is in the "soft switch" technology: On some of Sylvania's newer monitors they have incorporated what is called "soft switch" technology. This allows your ATX power supplied computer to turn your monitor on and off using it?s software controls. Therefore, your monitor?s light will always stay on blinking even when your computer is off. The monitor in normal operation consumes about 80W of power; in the "OFF" state it will be reduced below 8W. The "OFF" mode of the monitor can be controlled by the PC input signal or by pushing the soft-power button to disable the PC signal control for manually turning off the monitor screen. Thus, when the monitor is in soft-power "OFF" mode it still consumes a very small amount of power. For the purpose of making it noticeable to the user that the monitor is in soft-power "OFF" mode, we designed the power indicator to provide for a slow blinking signal (every 2 seconds). If you need to totally turn off the power, then the power cord would have to be unplugged. The same is true of the PC itself, but the PC does not provide for notification while in "OFF" mode.
